SIP Router Bootcamp, Berlin, Germany, Sep 1-4, 2009

2009-07-20T14:57:00.001+03:00

Next SIP Router Bootcamp will take place at the end of the summer, on September 1-4, 2009 in Berlin, Germany.

Teachers:

Daniel-Constantin Mierla - co-founder of OpenSER/Kamailio project in 2005, currently core-developer and member of project’s management board

Olle Johansson - Asterisk developer and member of the Digium Asterisk Advisory Board.

By end of 2008, Kamailio (OpenSER) and SIP Express Router (SER) started a joint collaboration under http://sip-router.org project, bringing together valuable developers and architects of SIP servers. Kamailio 3.0 and SER 3.0 (to be released soon) become compatible in terms of configuration file and extensions.

Learning to configure the SIP server is not easy, but is the key for a successful and secure VoIP business. The flexibility of SIP routing engine allows you to implement in no time innovative services, IP telephony, Instant Messaging, Presence and beyond. Asterisk comes to complete with rich media services and applications. Doing everything designed right and scalable saves time and money.

We create the opportunity for you, guided by experienced instructors, to learn how to build an Unified Communication platform from scratch using the SIP server engine and Asterisk.

2009-07-16T20:50:00.001+03:00

The roadmap to next major release of Kamailio (OpenSER), codenamed 3.0, was sketched during IRC meeting Jul 07, 2009, as:

- freezing in 1-1.5 months

- 1-1.5 months testing

- release by end of September/ beginning of October

Right now, current development state is:

- all but one module (seas) were updated to work with the new core

- several addons in kamailio core and tm still to be included in GIT master branch

- many new features developed: mecached, event_route, xml doc handling … see:

http://sip-router.org/wiki/features/new-in-devel

Kamailio (OpenSER) v1.5.2 Released

2009-07-15T20:49:00.000+03:00

A new release in 1.5 series is out. Kamailio (OpenSER) 1.5.2 is based on the latest version of branch 1.5, including many fixes in code and documentation, therefore those running 1.5.0 or 1.5.1 are advised to upgrade.

Source tarballs are available at:

http://www.kamailio.org/pub/kamailio/1.5.2/src/

Detailed changelog:

http://www.kamailio.org/pub/kamailio/1.5.2/ChangeLog

Download via SVN:

svn co https://openser.svn.sourceforge.net/svnroot/openser/branches/1.5 kamailio

Tag for this release can be browsed at:

http://openser.svn.sourceforge.net/viewvc/openser/tags/1.5.2/

Project site at SourceForge.net (still using old name):

http://sourceforge.net/projects/openser/

Binaries and packages will be uploaded at:

http://www.kamailio.org/pub/kamailio/1.5.2/

Modules' documentation:

http://www.kamailio.org/docs/modules/1.5.x/

What is new in 1.5.x release series is summarized in the announcement of v1.5.0:

http://www.kamailio.org/mos/view/Kamailio-OpenSER-v1.5.0-Release-Notes

Note: Kamailio is the new name of OpenSER project. First version under Kamailio name was 1.4.0. Older versions will continue to use OpenSER name. The source tree for current development version is hosted by SIP Router project, you can test it via:
http://sip-router.org/wiki/migration/kamailio-3.0-config

New module MI_RPC available

2009-07-14T14:04:00.001+03:00

Several days ago, a new module named mi_rpc was added to the source tree. The goal is to be able to execute MI commands using RPC interface from sip router core.

One big advantage of this is executing MI commands using the sercmd tool. sercmd is a command line interface, able to do auto completion for commands, used to change parameters, get insights of core and modules at runtime.

If you grabbed the source code (some guidelines at: http://sip-router.org/wiki/migration/kamailio-3.0-config ), then:

cd utils/sercmd

make

./sercmd

At the prompt: “mi ps”

See the readme of the module for more options:

http://sip-router.org/docbook/sip-router/branch/master/modules/mi_rpc/mi_rpc.html

You need to compile and load modules_s/ctl:

http://sip-router.org/docbook/sip-router/branch/master/modules_s/ctl/ctl.html

Two more modules updated

2009-07-11T21:35:00.000+03:00

Two of the last three modules that were not ported to use the new sip router core are ready now: nat_traversal and siptrace.

Particularly, siptrace was refurbished a lot. Before release, there are couple of new features that should get in trunk since sip route core offers support for such extensions:

- ability to filter the ACK for negative replies issued by sl module in the script

- ability to store stateless forwarded messages (now only stateful ones being stored)

Testing is very much appreciated, see guidelines at Kamailio 3.0 Config wiki page.

SIP Router Users Mailing List

2009-05-18T20:27:00.000+03:00

As the project entered the phase where it is usable with modules from both Kamailio (OpenSER) and SIP Express Router (SER) projects, a new mailing list has be created:

sr-users@lists.sip-router.org

You can subscribe to it at:

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

It is intended for community users, the early testers at this moment in time.

The other mailing lists available for the project are:

- sr-dev - for development related discussions
http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev

- sr-users-es - sip router Spanish community mailing list
http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users-es

SIP Router Ready for Testing

2009-05-15T20:25:00.000+03:00

The period of SIP Router integration phase is more and more approaching the end. Apart of 4 modules that are not integrated yet from Kamailio - seas, siptrace, uac_redirect and nat_traversal (work being undertaken) — the rest of 88 modules are ready for http://sip-router.org core.

There is now a page to collect guidelines for the default Kamailio configuration file used with sip-router. We invite all of you to test it, not only this one, but your private configs as well.
http://sip-router.org/wiki/migration/kamailio-3.0-config

Feel free to add to the wiki page or post questions about it to sr-users@lists.sip-router.org. This is a new list created for users of sip-router project, you can subscribe to it at:
http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users

At this stage, sip router can be used with modules from both Kamailio (OpenSER) and SER projects, mixed in same instance at the same time. Therefore you can choose the best ones that fit your needs. For Kamailio (OpenSER) users there is a page that tries to collect new features they got from SER side (still a lot to add there, hope ser developers will contribute what they find missing). Another page collects links for ser and kamailio users to find what the other project brings:
http://sip-router.org/wiki/migration/new-features-for-k-users
http://sip-router.org/wiki/features/inherited-features

It was not only integration work in the past months, sip router has quite a bunch of brand new feature. The wiki page to collect the summary is available at:
http://sip-router.org/wiki/features/new-in-devel

Jan just set online documentation portal, available for web browsing:
http://sip-router.org/docbook/sip-router/branch/master/

Common modules are located in directory ‘modules’ while kamailio and ser specific modules can be found under module_k and modules_s. Project’s wiki portal got also good content and it is under heavy work — note that everyone can contribute to wiki:
http://sip-router.org/wiki

Couple of core and tm features are not yet integrated or not exactly as they were in Kamailio. Please report the ones you are missing in your config at:
http://sip-router.org/wiki/devel/kamailio-integration#tm_and_core_extensions

It is the place that should set the priority rank for integration. I hope that in 1-2 months time frame to get into beta stage and prepare a stable release.

Many thanks for those that allocated resources to make things evolve to this stage and many thanks in advance for those that will start testing and help improving the sip router project.

New Module MemCached

2009-03-11T17:18:00.001+02:00

Courtesy of Henning Westerholt, a new module was added to the repository - 'memcached'. It allows to connect to a memcached server and supports following operations:

add key
get key
delete key
atomic operations

The operations can be done directly in the configuration file via pseudo-variables.

Further details can be found in the module documentation:

http://kamailio.org/docs/modules/devel/memcached.html

Memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic applications by alleviating database load.

SIREMIS Project Launched

2009-01-21T20:17:00.002+02:00

Asipto SRL has launched the SIREMIS Project, aiming to build web management interface for Kamailio (OpenSER). Later will follow also the sip-router.org project.

Under management of Elena-Ramona Modroiu, the project was developed so far by Asipto - http://www.asipto.com - using OpenBiz PHP framework — the target was to make it easier to extend for non-web developers. Soon, the project sources will be hosted on sourceforge.net SVN (project name: siremis).

Homepage of the project is:
- http://siremis.asipto.com

The first beta release is available for download and includes the features:

subscriber, database aliases and speed dial management
location table view
dispatcher, prefix-domain translation and least cost routing (lcr) management
access control lists (user groups) and permissions management
accounting records, missed calls and call data records view
hash table, dial plan table and user preferences table management
off-line message storage view
it was tested with MySQL but should support other sql-like DBs

Internal design:

developed on top of a framework: PHP/Web2.0/Ajax
XML Metadata driven extensions
Model-View-Controller (MVC) architecture

You can see some screenshots at:
- http://siremis.asipto.com/photos/siremis-screenshots/

For few days, a demo site can be accessed at:
- http://siremis.asipto.com/demo/
- username: admin and password: admin

Download and installation details:
- http://siremis.asipto.com/install/

We hope you will enjoy it and help to extend it. The plan is to release first stable version more or less at the same time with Kamailio (OpenSER) 1.5.0.

Send SIP Messages From Config File

2009-01-16T00:31:00.000+02:00

You can initiate SIP messages from Kamailio (OpenSER) configuration file ...

uac module provides a new function that allow sending sip requests from configuration file:

- uac_send_req()

http://kamailio.org/docs/modules/devel/uac.html#id2467912

It opens the door for a new bunch of things you can do now. I can think of now:

1) send IM alerts on special events

route { 
 $uac_req(method)="MESSAGE";
 $uac_req(ruri)= "sip:alert[at]kamailio.org";
 $uac_req(furi)="sip:server[at]kamailio.org";
 $uac_req(hdrs)="Content-Type: text/plain\r\n";
 $uac_req(body)="SIP request from:" + $si + ":" + $sp;
 uac_send_req();
}

2) turn lamps on for some sip phones on some events - e.g., snom:

http://wiki.snom.com/Features/LED_Remote_Control

3) talk server-to-server - here one example can be building a platform with a central server for accounting. Accounting is done at 200ok. So each routing server will build a csv list (time,callid, from tag, to tag, invite from uri, invite r-uri):

onreply_route[1] {

  if(status!="200")

    return;

  $uac_req(method)="ACCOUNTING";

  $uac_req(ruri)="sip:store[at]accounting.kamailio.org";

  $uac_req(furi)="sip:server[at]server1.kamailio.org";

  $uac_req(hdrs)="Content-Type: text/accounting-csv\r\n";

  pv_printf($uac_req(body), "$TS,$ci,$ft,$tt,$T_req($fu),$T_req($ru)");

  uac_send_req();

note that $T_req() is given by tm module, also with Kamailio trunk:

http://www.kamailio.org/dokuwiki/doku.php/pseudovariables:devel#tm_module_pseudo-variables

The accounting server:

route{

  # you should check the source IP also

  if(method=="ACCOUNTING" && $rU="store")

       sql_query("ca",

             "insert into accounting(timeval,callid,ftag,ttag,src,dst) values ('$(rb{s.select,0,,})','$(rb{s.select,1,,})', ...)",

             "ra");

      send_reply("200", "Stored");

... and you can put your imagination work ... there are plenty of new and cute features you can add on your service with this functionality ...

Approaching Kamailio (OpenSER) 1.5.0

2009-01-12T00:26:00.000+02:00

The preparations for releasing a new major version, 1.5.0, will start on Jan 26, 2009

The Kamailio (OpenSER) project approaches the time for a new stable version:

http://www.kamailio.org/dokuwiki/doku.php/development:release-policy

Proposed date to freeze the code is: Mon, Jan 26, 2009. It will follow about one month of testing and then the new version will be out.

There is a lot of new development since last major release 1.4.0, check a summary at:

http://www.kamailio.org/dokuwiki/doku.php/features:new-in-1.5.x

AFAIK, before release, 2-4 new more module are going to be introduced and couple of existing modules extended. This is a notification for all users and developers (existing or upcoming) to finish the work before the freezing date if they want to get their code in Kamailio (OpenSER) 1.5.0.

The 1.5.x series will be the last to use the current core. Next releases will be based on SIP Router project:

http://sip-router.org/

Merry Christmas and Happy New Year 2009!

2008-12-25T18:54:00.000+02:00

Day by day, we ended another year. 2008 was full of events, starting with one major release and six minor releases, participation to workshops and conferences wordlwide, adoption in new production environments and acknowledgement of running platforms with millions of users and billions of routed minutes/month using Kamailio (OpenSER), check the News archive at:

http://www.kamailio.org

There were sad events as well, including the hijacking of the old domain name after the rename in Kamailio, still the SourceForge project goes on, with same name, proving the genuine openser project:

https://sourceforge.net/projects/openser/

We maintained release 1.3.x series, last being 1.3.4, which still keeps the old name and is available at:

http://www.openser-project.org/mos/view/News/NewsItem/OpenSER-v1.3.4-Released/

Life is going on, from the the latest major release, version 1.4.0, the project boosted in new features, a summary of what is new since then is available here:

http://www.kamailio.org/dokuwiki/doku.php/features:new-in-1.5.x

An important share of effort was directed to clean the code and improve the stability and performance, a proof of maturity and the need to make the maintenance of the project easier and open for new comers. Lot of documentation was added in doxygen format inside the source code, Devel Guide was published, new developers can start new easier to enhance the application.

Reference moment for the future was the launch of SIP Router project in November - a concentration of many people with great SIP and VoIP expertise, backed up by huge programming experience in this field. This came to strengthen the development workforce, to ensure the reliability, to remove the doubts of what projects is better now or is going to develop better in the future.

http://sip-router.org

So, 2009 is an year that announces already great achievements to be done in its first half:

1st Quarter - release of Kamailio (OpenSER) 1.5.0
minor releases for 1.4x and 1.5.x
2nd Quarter - release of SIP Router project as stable version
dedicated meeting to celebrate the first operational SIP Router and draw future directions

With the release of SIP Router project, everyone gets access to the features provided by Kamailio (OpenSER), SIP Express Router and OpenIMSCore projects:

http://sip-router.org/benefits/

Looking forward to a fruitful 2009!

Truphone - Call With Your iPod Touch

2008-12-10T16:41:00.002+02:00

On 4th of December, 2008, Truphone increased its target market, making available their smart VoIP client available for iPod Touch:
http://truphone.blogspot.com/2008/12/turn-your-ipod-touch-into-phone-with.html

... charming and handy to use. Still loyal to my Nokia phone, but the latest developments from Truphone for iPhone and i'Touch are really tempting ...

Request/Reply Attributes Access From TM

2008-12-09T19:50:00.001+02:00

Latest developments provide access to the attributes of reply while processing the request and vice-versa.

The TM module introduces two new features:

access to SIP request attributes while processing a reply belonging to same transaction
access to SIP reply attributes while processing a request belonging to same transaction

Functionalities come as pseudo-variables, $T_req(pv) and $T_rpl(pv) - where pv can be any pseudo-variable, check documents at:

http://www.kamailio.org/dokuwiki/doku.php/pseudovariables:devel#tm_module_pseudo-variables

The new pseudo-variables can be used:

in failure_route to get the attributes of the reply causing the failure route. You can take decisions what to do with the request based on reply details
in onreply_route to get the attributes of the request. you can take decision what to do with the reply based on request attributes.
in acc to store data from reply
in C code (modules)

Note that couple of PV are disabled for these cases (PV will return null) - these are the PV that alter/depend on the context of the processed message, like $Ts, $Tf (but you can use $TS and $TF), $time, destination set attributes. The $avp(...) will be current avps, as they are stored in a global list. Also, in case there is a timeout or other reply generated by kamailio itself, $T_rpl(pv) will return null as there is no real reply structure behind.

Example, print the source ip of the reply in failure route:

failure_route[1] {

    xlog("reply received from: $T_rpl($si)\n");

SQLOPS Module

2008-12-08T15:47:00.000+02:00

sqlops module focuses to offer fast and easy access to SQL backends directly from the configuration file. Among its features:

many DB connections - the module can connect to many databases on different servers using different DB driver modules (mysql, postgres, ...) at the same time.
many DB results - the module can store many results of different SQL queries in separate structures at the same time. Thus is possible to work in parallel with several DB results.
access via pseudo-variables - the content of SQL query result is accessible via pseudo-variables.
array indexes - fast access to result values via array possition: [row,column].
persistence in process space - a result can be used many times in same worker process. Query once, use many times.

Here is an example of fetching and printing the content of a table:

...

modparam("sqlops","sqlcon","ca=>mysql://openser:abc@localhost/openser")

...

sql_query("ca", "select * from domain", "ra");

xlog("rows: $dbr(ra=>rows) cols: $dbr(ra=>cols)\n");

if($dbr(ra=>rows)>0)

    $var(i) = 0;

    while($var(i)<$dbr(ra=>cols))

        xlog("--- SCRIPT: column[$var(i)] = $dbr(ra=>colname[$var(i)])\n");

        $var(i) = $var(i) + 1;

    $var(i) = 0;

    while($var(i)<$dbr(ra=>rows))

        $var(j) = 0;

        while($var(j)<$dbr(ra=>cols))

            xlog("[$var(i),$var(j)] = $dbr(ra=>[$var(i),$var(j)])\n");

            $var(j) = $var(j) + 1;

        $var(i) = $var(i) + 1;

sql_result_free("ra");

...

Other advantages than the ones listed above against old avp_db_query() function:

- does not mess up fields position if the value in db is null

- use private memory, no locking

- does not iterate through linked (avp) list to get each field, direct

reference to each data structure in result array, thus much faster.

PV and Transformation API Updates

2008-12-07T00:51:00.004+02:00

Pseudo-variables and transformations implemented in core for Kamailio (OpenSER) versions <= 1.4.x are now moved in pv module.

This is part of cleaning up the core, in order to keep it slimmer and less exposed to bugs. There are modules and use cases that need no PVs, therefore no need of keeping the implementation of about 100 pseudo-variables and over 30 transformations in core.

Now the core includes only an API that allows to:
- register pseudo-variables
- parse name, evaluate and set value of pseudo-variable
- register transformations
- parse name and evaluate transformations in config file

$shv(...) - shared variables, and $time(...) - broken down time, were moved from cfgutils module to pv module ($shv(...) depends on $var(...)).

To summarise, for devel version (upcoming v1.5.0 release), if you need $ru, $avp(...), $var(...), a.s.o. in your config file you have to load pv module.

Two new pseudo-variables were introduced with this occasion, $TS and $TF, see more:
- http://www.kamailio.org/dokuwiki/doku.php/pseudovariables:devel#string_formatted_time_-_current
- http://www.kamailio.org/dokuwiki/doku.php/pseudovariables:devel#unix_time_stamp_-_current

Code restructuring for Kamailio 1.5.0

2008-12-05T00:44:00.000+02:00

The efforts to consolidate the core of Kamailio (OpenSER) and reduce duplicates of code are going on. Several modules with related functionalities were merged in others for a better and easier maintenance.
No functionality was removed, it can be now just found
in a different place.

1. gflags module
The functionality of this module was integrated into the cfgutils module. The internal functionality, function names and MI commands are the same, the parameter “initial” was renamed to “initial_gflags”.

2. options module
The functionality of this module was integrated into the siputils module. The function name was not changed, all parameters were prefixed with the "options_” string.

3. uri module
The functionality of this module was integrated into the siputils module. The function names were not changed, internal functionality is the same.

So starting from the release 1.5 you'll need to fix your "loadmodule" statements and some parameter prefixes in your config if you use one of the mentioned modules. Documentation for the functions can be found in the usual place:

First Kamailio (OpenSER) Module Ran On SIP-Router

2008-11-21T23:19:00.002+02:00

Yesterday evening first Kamailio (OpenSER) module ran on the common layer core+tm provided by sip-router project. That was siputils (new module in Kamailio devel version).

Soon after:
- xlog module was ready too, with just an extra define in Makefile, marking the inclusion of pseudo-variable and transformation API in sip-router — one can do color printing via xlog. Note that all pseudo-variables and transformations will be moved in PV module as discussed some time ago on Kamailio devel mailing list.
- DB API of Kamailio and SER were included as library and other modules become compilable with sip-router

For reference:
http://lists.sip-router.org/pipermail/sr-dev/2008-November/000071.html
http://lists.sip-router.org/pipermail/sr-dev/2008-November/000077.html

http://lists.sip-router.org/pipermail/sr-dev/2008-November/000082.html

Once MI and statistics APIs will become libraries as well, then many other Kamailio (OpenSER) modules shall work more or less out of the box (some statistics done in core and 1-2 mi commands will miss in the first phase). Then it comes the second big step, after module integration, config language update — after that point we are kind of 70% ready.

All these happened in just few days since source code repository (GIT) was up … it looks like we will get most of the features from Kamailio (OpenSER) and SIP Express Router (SER) together sooner than expected … let’s see …

Karlsruhe Meeting Photos

Karlsruhe Meeting Minutes

2008-11-21T22:57:00.002+02:00

SIP Router Project - Kick Start Meeting minutes:

* development side: move forward, sip-router.org source repository should be up next week
* end of January we should have a runable core+tm with support for the most used features from both Kamailio (OpenSER) and SIP Express Router (SER) (100% support might be a little delayed as some features may become obsolete)
* Kamailo next-next release (probably after spring next year) will be based on sip-router core+tm
* next or next-next SER release will be based on sip-router (SER might make another 2.1 release from the current CVS, since the code is ready - to be discussed)
* future releases will most likely be common and will unify all or most of the modules (depending on everything up to that point working ok)
* copyright: patches that are not accompanied by (c) claims will not add to the (c). We should put this on a web page and when in doubt we can ask the patch author for confirmation. While it’s likely this has no or very limited legalvalue (especially in Europe), it will server at least as a gentleman agreement. We need this because:

1. we need the agreement of all (c) holders for the GPL code to add licensing exemptions (e.g. we need to add an openssl linking exemption) and it’s easy if we have a known “small” set of (c) holders
2. people might not like having multiple (c) notices on files they created, just because someone did send a trivial or not so significant patch (note: “trivial” and “significant” are very relative). On problems, probably the board will decide, if nobody gives up the claim we’ll fork the module (worst case, to be avoided as hard as possible).

* forking modules: highly discouraged, but allowed
* unmaintained and rarely used modules: removed after a grace period
* board: for now we continue to have 2 boards, SER and Kamailo at least until we have something runable. In the meantime we should think/discuss how the common board will look like: how it will be elected and for how long, “composition” (how many devels, how many from the user community, testers a.s.o)
* testing: very important, Jerome proposed having beta-tester groups and stressed out the importance of dynamic tested. Everybody seems to agree, but there are doubts about finding beta-testers volunteers.
* release management: we need a release manager for each release
* documentation: Kamailio uses a wiki for core, and docbook .xml for modules, SER use NEWS (txt file) for core and docbook for modules, but it’s in the process of migrating to a more man page friendly format (still .xml). More discussion is needed, between the main doc writers from both sided.

sip-router.org:

* GIT repository should be up next week
* sr-dev mailing list should be used for technical dicussions related to merging the cores
* new features mails should be cc’ed to sr-dev too (very important especially when core or tm is involved).
* todo: find easy to remember short name

Related projects:

* some modules may be on separate repositories for a while (e.g., openimscore), maintained by their devs for using them out of the box with sip-router
* stand-alone application servers (Voztelecom/WeSIP, Iptego/SASI) may merge the communication interface specs in the future.
* it is a need for a place where to collect basic info about related projects

Further steps:

* new meeting, to be organized somewhere end of winter/beginning of spring 2009 (topics: celebrate first integrated working version, discuss further development of sip-router)
* setup of adjacent tools that help developing code and documentation (e.g., wiki, tracker)

General opinions:

* there are x-ser platforms running milions of users, sip-router must provide a rock-solid SIP server, esure trust and project reliability
* while having a strong focus on above item, innovation shall not be stopped, new features to be added as module to avoid effects to core and main modules
* very important modules (e.g., usrloc, registrar, …) should be protected as much as possible, patches and new features to be carefully reviewed not to affect stability and interoperability
* improvements to most important parts to be discussed on sr-dev mailing list

Carrierroute Extensions In Kamailio 1.5

2008-11-20T22:42:00.000+02:00

Courtesy of Henning Westerholt and 1&1, carrierroute module got a bunch of new features that makes the module more flexible than ever and also fixed a few annoyances in the module usage:

1. Improved routing data loading

The module supports now the partioned loading of routing data during startup and reloads. In the past when one want to load big route set it was necessary to increase the private memory pool size, as the data was stored temporarily there. Now this is not necessary anymore, its possible to load route sets with e.g. 400.000 rules in the standard (private memory) configuration.

2. Efficient matching of domains and carriers

In the old implementation a simple linear list was used, this was replaced with a fast binary search function. The module can now look up carrier and domains in most cases with O(log n), which makes it more scalable when a big number of carriers and/ or domains are involved. Only when a dynamic string is used in the config script a full list search is needed.

3. Support for non-numerical prefix matching

Carrierroute now supports also the prefix matching with non-numerical characters. Its possible to use the entire standard ascii charset for route matching. This is configurable with a module parameter, the default implementation is still the know digit matching method. Please keep in mind that memory demands will increase somewhat when the extended matching is used. This additonal flexibility will probably bring a small overhead with it, as some additional logic is involved during the routing deciscion. But this will not be noticable on today standard servers.

4. Extensive refactoring and cleanups

Restructured and refactored the code in most areas, to make the module implementation and structure more understandable, maintainable and extensible. Replaced the usage of custom datatypes and fixup functions with the standard core implementation, switched to the autogenerated DB interface and use now standard glibc functions e.g. for the list search. Changed certain structures to not store the full name of carriers and domains in memory to save space and got finally rid of this mismatch between internal and external carrier ID.

More details about the new implementation can be found in the documentation at:

http://www.kamailio.org/docs/modules/devel/carrierroute.html

SIP Router Project - The Meeting In Karlsruhe

2008-11-12T11:11:00.002+02:00

Because of taking several days off, a complete report might show up a bit later, now a (short) summary...

First, many thanks to 1&1 for hosting the event and everyone that participated in such short notice. There were representatives from 10 companies:
- 1&1
- FhG Fokus
- Telio
- Asipto
- iptelorg/Tekelec
- Voztelecom
- Iptego
- Itsyscom
- Longphone
- Basis AudioNet
Some pictures should be published in the near future.

After going in short introduction and presentation of the goals from the point of view of each project (SIP Express Router (SER) and Kamailio (OpenSER)), we focused on:
- identification of potential points of conflicts and how to get to a resolution in such case
- code integration for common layer of the first phase
- future development and proposals of new features
- management of the larger eco-system that includes related projects and business entities

I will do several posts detailing what was discussed and proposed there for SIP Router project in few days. meanwhile, the outlines:
- it is hard to avoid conflicts just by some clear and strict rules, so the common sense should lead the collaboration and discussions
- GIT repository should be up in several days so the work can start, with a time line of 2-3 months from now to get core and tm in a very good shape of integration
- another meeting shall be set in about 3 months time, to allow enough time for people to be able to attend, adjust the development and look more deep at the future. While a lot of focus in the next months will be on integration, development of new features won't stop -- for example, steps to a partial asynchronous processing are undertaking, couple of new modules are planned for release, several other modules to bring new functionalities
- we should encourage and promote the development of related applications, like web interfaces, management tools, applications servers -- they add value for community and business

IRC Devel Meeting Summary - Nov 06, 2008

2008-11-11T11:03:00.003+02:00

I am trying to summarize the outcome of the IRC devel meeting from last Thursday, Nov 06, 2008. The log is available here...

Regarding the 1.3.x series, we set the 20th of November as the date for 1.3.4 release. There are several fixes and this branch is still used in many production environments, so it worths investing time in it. There are some updates in 1.4.x to be ported and some issues to be investigated.

For a new 1.4.x release (the 1.4.3) we look for the beginning of December as the time frame for setting the date of the release.

The 1.5.x rises in the first phase the question of a shorter time release, as we have lot of new features already implemented, see:
http://www.kamailio.org/dokuwiki/doku.php/features:new-in-1.5.x
http://www.kamailio.org/dokuwiki/doku.php/roadmap:1.5.x

Unfortunately some of the new features are not completed yet (e.g., htable, carrierroute updates, PV migration) so we will stick to 6-8 months release cycle. The next major one that will use the common layer (core and tm) from sip-router could be done in a shorter time than
usual. So, beginning to mid of January should be the time to freeze the code for a release date somewhere in end of January or February.

An important aspect approached during the discussions was the release management and testing management. Perhaps we need to appoint a person to manage releasing process in order to have a better synchronization of the developers. As everyone agrees, testing is very important and we try to improve it. There is a testing suite included in the source tree right now, used for static testing.

The idea of a dynamic testing and testing community was introduced and hopefully we can attract people and build a group of beta testers. There is a proposal of how to implement and what to take care of, probably this one has to continue on devel and users mailing lists for a proper
organizational structure.

GIT became as a subject of migrating from SVN, because of its features for a distributed development environment. However, sourceforge.net does not have such offerings, so it is not possible now anyhow. However the sip-router.org will use it.

Regarding the sip-router.org project, we focused on short term goals, acknowledging that we have several modules offering same functionality but relying on different underlaying data structures, this have to co-exists for a longer time. For the first phase, core + tm the overlapping is rather small, the two projects insisting in the past to improve different aspects of them.

Unfortunately I forgot to bring up some punctual topics proposed, mainly related to tm failure route calling in case of sending error and reply handling/dropping in onreply_routes.

The SIP Router Project

2008-11-04T10:35:00.003+02:00

The SIP Router Project started aiming to build a solid open source SIP routing platform, based on collaboration of the SIP Express Router (SER) and Kamailio (OpenSER) teams.

Developers of these two projects believe that an united and non-conflicting environment will bring many benefits, to them, community members and companies.

- bring together the developers and user communities of both projects
- reduce maintenance overhead
- avoid duplicated efforts in development
- develop a core framework that is flexible, extensible and scalable
- promote and build a solid open source SIP server project
- ensure business credibility
- make future forking undesirable, this harms everybody, affects credibility and business

You are welcome to join! Visit:

http://www.sip-router.org

Mailing list:

http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-dev

There will be a meeting for concluding the collaboration and kick start the integration. Everybody is welcome to join. See more details:

Simple Web UI

2008-10-29T11:21:00.002+02:00

Graham Wooden posted on Kamailio (OpenSER) users mailing list the news about a simple web UI.

After seeing that CDRTool was a little too complex and complicated for that matter, he decided to take the CDR gathering and add a "simple" web UI to it, allowing to maintain SIP users and various settings (some are not shown in this version right now).

As a preface - this is very plain, not stylized, no CSS, no fancy layouts, etc.

Link: https://www.leasedminds.com/ui/

I hope people see value with this as Graham too, and will start contributing to develop it to a nice and robust web UI for Kamailio (OpenSER).

Analysis of a VoIP Attack

2008-10-23T17:49:00.002+02:00

Klaus Darilion, developer and member of management team of Kamailio (OpenSER) project, published a deep analysis of a recent VoIP attack.

Several IT news websites reported VoIP attacks against home users containing lots of myths and incorrect statements. Unfortunately, they also give wrong security advices.

Klaus decided to write an article about this attack and give some advices for protection. The document is available for download at:

http://www.ipcom.at/index.php?id=565

LCR Module Enhancements

2008-10-17T11:28:00.002+02:00

Juha Heinanen just committed to Kamailio (OpenSER) trunk an enhanced version of lcr module, including new features and increasing performance:

* New high-performance implementation that keeps lcr information in in-memory hash table, whose size can be given in a new module parameter 'lcr_hash_size'. See lcr/README for lcr functions' execution time.
* New 'weight' field in 'gw' table that can be used to assign a gateway a weight among gateways of its group.
* Support for prefix_mode=1 has been dropped.
* lcr_dump MI function has been split into lcr_gw_dump and lcr_lcr_dump functions.
* lcr_reload function is now executed under a lock thus minimizing race conditions.
* Regular expressions are now Perl 5.x, instead of POSIX, compatible due to use of PCRE regular expression library. This allow pre-compile in shared memory at load time, avoiding checks and regexp compilation at runtime.

Asynchronous syslogging

2008-10-16T16:16:00.002+02:00

Courtesy of Henning Westerholt, Kamailio (OpenSER) development version has now support for non-blocking logging. This was implemented using the syslog-async functionality from the dnsmasq server [1] from Simon Kelley.

The standard Unix syslog() library routine can block waiting for the syslog daemon. On some systems, using a datagram socket for /dev/log avoids endless waits, but on Linux, even this does not work. Try typing:

killall -SIGSTOP $pid_of_syslog

into a root terminal on a non-critical machine. Then generate traffic to get some logs, eventually, the server will stop. This blocking of the syslog daemon can happens because of bugs, or if the daemon waits for external events, like DNS lookups.

Instead of blocking, log-lines are buffered in memory. The buffer size is limited and if the buffer overflows log lines are lost. When lines are lost this fact is logged with a message.

This functionality can be enabled with setting the define SYSLOG_ASYNC in the Makefile.defs file. The default is the normal log functionality from the system library, nothing changed if the define is not set.

You can get the code from the svn repository:

svn co https://openser.svn.sourceforge.net/svnroot/openser/trunk kamailio

Debian packages for several debian releases are available at: devel.kamailio.org.

sip:wise - launch of new products

2008-10-14T10:08:00.005+02:00

SIPWISE, the creator of Kamailio/OpenSER Web Configuration Wizard launched two new products:

- sip:carrier - a secure and scalable Class5 SIP platform for ISPs, ITSPs, Telcos, Mobile Operators and Carriers, packed in highly available, high-performance hardware.
- sip:provider - a turnkey platform enabling small and medium size operators to launch professional VoIP services within a couple of days.

It is just wonderful to see new products that uses Kamailio/OpenSER on the market, especially coming from those being tight involved in the project, this time is the case of Andreas Granig, long time developer of Kamailio/OpenSER.

Just few time ago, I wrote about Oigaa Virtual PBX Service, coming from Voztelecom and Jesus Rodriguez, another long time developer and supporter of Kamailio/OpenSER.

Registrar Enhancements

2008-10-06T18:26:00.003+02:00

In the last time several enhancements were added to registrar module to help in dealing with user location records. This correlated with the new modue pv shall give lot of control over the destination set for calls.

To get the latest Kamailio (OpenSER) devel version, check out the latest svn:


svn co https://openser.svn.sourceforge.net/svnroot/openser/trunk kamailio

The news in registrar module are:

- ability to unregister all contacts for a SIP addres - there is a new function: unregister(table, uri)
- ability to store and maintain single contact per user - the save() function accepts a new value for flags parameter (0x04) to restrict to one single record in location table
- ability to access the attributes of all contacts for a user - there are two new functions: reg_fetch_contacts(table, uri, profile) and reg_free_contacts(profile) to make available/release the contacts for a SIP uri. After fetching the contacts, the attributes can be accessed via pseudo variable $ulc(profile=>attr).

For more details see the README:

http://www.kamailio.org/docs/modules/devel/registrar.html

Here are couple of use cases:

1) only one contact per user


save("location", "0x04");

Note that if you have couple of phones registering for same user, the one that sent last REGISTER message will be the only ringing.

2) check if a user is calling from a registered device and if not, deny the call


if(!reg_fetch_contacts("location", "$fu", "caller"))
{
   sl_send_reply("403", "Please register first");
   exit;
}
$var(i) = 0;
$var(found) = 0;
$var(contact) = $(ct{nameaddr.uri});
while($var(found) == 0 && $var(i) < $(ulc(caller=>count)))
{
   $if($var(contact)==$(ulc(caller=>addr)[$var(i)]))
     $var(found) = 1;
   else
     $var(i) = $var(i) + 1;
}
if($var(found) == 0)
{
   sl_send_reply("403", "Please register first");
   exit;
}

For the future:
- unregister() to get a $ulc(...) variable as parameter to unregister a specific contact
- drop a branch via pv module

Towards Kamailio v1.5.0

2008-10-01T19:22:00.002+02:00

Recently we just released 1.4.1 in the latest stable branch, so it is time to give updates on the development version of the project to be released as v1.5.0. In less that two months since 1.4.x release series was branched, lot of new things happened - new modules and features, code refactoring and fixes.

The outline of the new additions:

Benchmark: RTPProxy v1.0 with OpenSER 1.3

2008-09-29T17:43:00.006+02:00

Transnexus has done an interesting analysis of using RTPProxy 1.0 with OpenSER 1.3, of course specific with their use case.

It has very interesting results, you can check here:

http://www.transnexus.com/White Papers/OpenSER_RTPproxy_test.htm

There was a lot of discussing regarding space for improvements and tunings to get better performances on the mailing lists, but still it is a good reference to be used. The page includes details about everything you need to do the test by yourself.

Transnexus is the developer of OSP module in Kamailio/OpenSER.

Ekiga 3.0

2008-09-25T20:04:00.004+02:00

Ekiga, the open source SIP softphone, announced yesterday the release of Ekiga 3.0.

There are many new features, including SIP SIMPLE presence. Check the release news at:

http://blog.ekiga.net/?p=97

Congratulations to the team, it looks very promising and I am just waiting for the Debian packages to try it out.

Skype Channel In Asterisk

2008-09-25T19:07:00.000+02:00

Last day of AstriCon brought out a very surprising news: official Skype channel in Asterisk from Digium, as there is a press release from both sides.

Link to official press release.

It looks like the cost will be per channel and licenses are available from Digium via Asterisk market place.

This means a lot in bringing Skype users connected to SIP world.

Generic Data Container

2008-09-24T20:00:00.000+02:00

A new feature that allows to store and share arbitrary data across Kamailio (OpenSER) configuration file is available

Elena-Ramona Modroiu has just introduced a generic hash table container for usage in configuration file. The hash table is in shared memory, therefore the values are global over all kamailio processes.

The items in hash table can be accessed via $sht(name). The name can include pseudo-variables that will be evaluated at runtime. In this way, the hash table can be used to store data per user or other key and can offer functionality of dealing with array of values.

An example of how to protect against dictionary attacks is in the README:

http://www.kamailio.org/docs/modules/devel/htable.html

As a roadmap for the new module, planned for addition:
- MI commands to get/set items in hash table
- ability to save/load in/from database
- ability to init items at startup
- auto-expire time for items

This completes global variables space along with shared variables $shv(name)) which are single value and allow only static name, but they are faster to access (see cfgutils readme file for more details on $shv(name)).

Cisco Buys Jabber.com

2008-09-23T10:11:00.004+02:00

Two weeks after end of SIP-XMPP Workshop in Paris, an important move has been announced on the Instant Messaging and Presence market: Cisco, network device and telco vendor, to acquire Jabber Inc.

http://newsroom.cisco.com/dlls/2008/corp_091908.html

Jabber leverages open standard eXtensible Messaging and Presence Protocol (XMPP) to provide enterprise class unified communication platforms. Yet another big company invests in XMPP after Google selecting XMPP for their GTalk service.

Kamailio (OpenSER) includes its SIP/SIMPLE-XMPP gateway for a while now, although still in beta stage. With a speed up of IM&P growing market, the interoperability between SIP and XMPP becomes an important fact that can lead to successful communication service.

Oigaa Virtual PBX Service

2008-09-22T17:22:00.003+02:00

Jesus Rodriguez, Kamailio/OpenSER developer and FreeBSD packager, announced today on his blog the launch of new products and services under name Oigaa:

http://www.voztele.com/esp/productos_servicios_voip/centralita_virtual_oigaa.htm

Voztelecom is one of the major supporters of Kamailio/OpenSER project, developing the WeSIP Java SIP Servlet Application Server and seas module. Many of their products and services run on top of several Open Source applications, among them Kamailio/OpenSER and Asterisk.

Good to see such news that underline the power and flexibility of Open Source!

Networking groups on Facebook and Linkedin

2008-09-22T13:04:00.002+02:00

For a while now there, you can find groups named "OpenSER" and "Kamailio" on both Facebook and Linkedin Social Networking portals.

If you want to meet people and make connections in Kamailio/OpenSER eco-system and you are member of one of those portals, then join the groups. Access is granted to everyone that applies to join, immediately on Facebook, after group manager approval on Linkedin (portal policy).

Kamailio (OpenSER) Presence Server: Dialog Info Support

2008-09-19T19:50:00.002+02:00

Developed by Klaus Darilion and sponsored by Silver Server (www.sil.at), Kamailio (OpenSER) introduced support for Dialog Info presence states - RFC4235 - INVITE-Initiated Dialog Event Package.

There are two new modules introduced:

* pua_dialoginfo: gets dialog states from dialog module and sends PUBLISH with the dialog state in RFC 4235 conform XML documents
* presence_dialoginfo: extends presence module to handle PUBLISH with dialog-info. Allows aggregation of multiple XML documents into one document.

With these modules you can have BLF without the need for an PBX (Asterisk). It is know to work with SNOM and Linksys phones. Linksys requires some tweaking with module parameters.

For more see the readme files:

A1 InnovationDays Remarks

2008-09-16T11:19:00.004+02:00

Returning from about two weeks of journey, I am catching up with work now. However, it worth to mention here some events I attended during past weeks.

The A1 InnovationDays Sprint was really challenging.
http://www.a1innovations.at/en/static/a1innovationdays

While participating to other coding sessions in the past, this one had the premises to make it great:

- nice location, one hour drive from Vienna, Austria, at Monastery Und in Krems. An old site turned into a convention place

- competition - five teams ran head to head to win. Finally the project "Spontaneous live comment as A1 sports reporter" got the prize, but I could say all the projects have big potential and the results after two days of coding were impressive: "Thunderbird plug-in for Unified Communications", "SIP Website Widget", "Automated Audio/Video Greeting Service" and "SIP extension for Disko framework". I will try to detail each one in separate posts

- vast knowledge base - it would be hard to get again in same room technical people from various domains working together: Web 2.0, graphic design, SIP, voice and video processing, embedded systems, GUI, GSM/Mobile technology, IMS

The only barrier seemed to be the weather, very nice, warm and sunny, trying to attract out attention away from coding.

However, the most important aspect of the event was the implication of the A1 - Mobilkom Austria in such event. It is the first mobile operator I have seen encouraging Open Source initiatives. Worth congratulations and let's hope they will be followed by other similar companies.

Kamailio updates

2008-09-16T10:14:00.003+02:00

Some updates concerning two main topics discussed on the mailing lists. First, the project name, many expressed the concern that a rename in short time will create more confusion. As we are not in front of a new major release, I think it is better to postpone this process for a while and focus on the second topic, the organization for the project.

For this one, I have to thank personally to many people from the list that wrote us, giving suggestions and helping finding solutions. As a result, we are working to create the draft of statute for organization, but we are also investigating the option to join an existing
organization, dedicated to hosting of open source projects.

Meanwhile, the svn repository got couple of new features as well as refactoring of some modules. 1.4.1 will be released soon as we got a bunch of important fixes in the 1.4 branch. Most probably another release in 1.3 branch will follow.

Check the website for updates:

OPENSER renamed to KAMAILIO

2008-07-28T23:47:00.002+03:00

Here is the announcement of project rename:

"OpenSER project and the community around it have grown considerably in the past three years. Because of its extensive development and high adoption rate, conflicting interests related to the OpenSER name and similar trademarks emerged.

Consequently, we have been forced to find a new name for the project that stands on itself and represent the project in its future expression.

Starting with version 1.4, OpenSER is called Kamailio. Existing OpenSER users can keep on enjoying the benefits of the best open source SIP server available on the market under this new name.

All project infrastructure like the website and mailing list will be in the future accessible under the kamailio.org domain, but we will keep the old one functional for a transition period to make the switch as easy as possible for you.

Kamailio is a hawaiian word. Kama'ilio means talk, to converse. It was chosen for its special flavour. It is hopefully easy to remember and the meaning fits well with the project purpose. We hope you like it too!"

RTP Proxy in Erlang

2008-07-24T10:21:00.001+03:00

Just found this project:
http://code.google.com/p/erlrtpproxy/

erlrtpproxy seems to be a RTP relay for OPENSER written in Erlang, an alternative to RTPProxy and Meidia Proxy. I didn't dig for more details, but I guess it is working together with the nathelper module in OPENSER.

Hope that Erlang fans will enjoy it.

Updates of NAT Traversal Solutions for OPENSER

2008-06-24T11:25:00.000+03:00

There were lot of development efforts in the two options available for NAT traversal with OPENSER.

Mediaproxy relesed next generation version: v2.0. More details at:

http://ag-projects.com/MediaProxy.html

Rtpproxy brings lately lot of new stuff, information is available at the dedicated site:

Approaching OPENSER v1.4

2008-06-12T10:39:00.003+03:00

The time for a new major release is approaching. Last minute discussions about some lately introduced code keeps the situation a bit unclear for the moment regarding the release day.

However, this post tries to underline the new features and important aspects that happened during last development cycle.

There are six new modules:
- db_oracle - database driver to connect directly to Oracle servers
- dialplan - regular expression based dialplan management
- nat_traversal - helper for nat traversal
- peering - RADIUS based peering
- ratelimit - call rate control module
- userblacklist - user based blacklisting

Lot of other new features and refurbishing in existing modules such as carrierroute, dispatcher, dialog, mediaproxy, msilo, cfgutils, pdt, textops.

Review of the DB API, fixup functions, new transformations and pseudo-variables are some of the core updates.

Related to this cycle, worth to mention the first OPENSER Devel Guide, a free, electronic book available at:

http://www.asipto.com/pub/openser-devel-guide/

and first printed book about OPENSER:

Building Telephony Systems With OPENSER.

I encourage everyone to start testing the upcoming OPENSER 1.4. Will be a big step forward.

OPENSER Dinner, Berlin - remarks

2008-06-06T10:11:00.001+03:00

What can I say first, great beer! Although, since I have been there last time, the place has changed the name, still nice and good quality.

The talks focused a bit on the two events taking place in Berlin, the AsteriskTag and the LinuxTag. Part ot SUN/OpenSolaris team joined us -- some one there worked hard in the past to make OPENSER compiling on OpenSolaris with the native compiler. Thanks.

As the VoN show in Amsterdam was canceled, this was the last social event in this cycle. I returned to work at ASIPTO, preparing for a new major release.

AsteriskTag and LinuxTag 2008 - week in Berlin

2008-06-05T15:10:00.000+03:00

I covered a bit about AsteriskTag2008 and LinuxTag2008 at:

http://www.asipto.com/index.php/2008/06/04/remarks-asterisktag-and-linuxtag-2008/

There you can find links to some photos and the slides I presented in the first day of AsteriskTag.

I had no photos from the OPENSER dinner in Berlin, on the 28th, but I will post about soon.

OPENSER Dinner, Vienna - remarks

2008-05-25T16:27:00.004+03:00

Very good restaurant - delicious food and local made beer - credits for selection goes to Andreas Granig. Located in the old part, in the city center, the place was somehow protected by the tourists crowd, offering a quite atmosphere.

As we got two visitors from Bratislava, Slovakia, the discussions went global wise. A hot topic (I guess not only there) was the cancellation of VoN show in Amsterdam. What will be the meeting place from now on for the VoIP guys as the VoN disappeared? Who knows, lot and lot of discussions and opinions here and there on the web forums and mailing lists...

Personally I got an update regarding WiMAX, deploying phase started in some countries. Although I know there are still many issues, the pressure of production environments will give more confidence and attract investors and creation of new or better products and solutions for this technology.

And of course, answering many times, again and again, it is VoIP in that dark castle in Transilvania, only SIP, SIP, SIP (I think is actually lower case :-) )...

Interview: Mysql and Openser

2008-05-24T15:36:00.000+03:00

I have found an interesting interview by MySQL with Juha Heinanen, developer and management board member of OPENSER Project. Targeting the carrier grade deployments, the key components approached are the MySQL cluster and OPENSER, to leverage reliable and distributed storage system for routing large volume of VoIP calls.

See the interview here.

OpenSER Social Networking - ROSDEV2008

2008-04-17T21:14:00.003+02:00

The fist OpenSER social networking event took place in Bucharest, Romania, Apr 12, 2008. It was together with the folks at ROSDEV2008. From the OpenSER mailing lists, you may recognize in pictures people like: Dan Bogos, Elena-Ramona Modroiu and Daniel-Constantin Mierla (that's myself).

There were other people at the event using OpenSER -- see the presentation about VoIP in the University Campus -- and we were able to conduct constructive discussions about VoIP in general. Apart of that, it was quite a hot spring day (over 25 Celsius), so the rest was about beer and good food in a typical Romanian restaurant. Here are links to photo albums and videos from ROSDEV2008 and the diner afterwards.
