Blog by MiConDa

As of today, this blog will get only sporadic updates. The most of the blogging activity will take place at:

http://by-miconda.blogspot.com

OpenSER renamed to Kamailio one year ago, therefore the name is pretty obsolete now. Moreover, it is a lot to blog about SIP-Router.org project and other SIP/VoIP related things.

Update your bookmarks and rss feeds! See you at the new address:

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

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.

New module MI_RPC available

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:

Two more modules updated

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.

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

SIP Router Ready for Testing

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.

Amoocon 2009 Presentation

Slides presented at Amoocon 2009, Rostock, Germany, are now available at:

http://sip-router.org/pub/events/2009-05-Amoocon/2009-amoocon-sip-router.org.pdf

The two day event, although Asterisk centric, brought many people from different projects and technologies around SIP and VoIP. Very interesting talks about integration with web and social networking, SS7 or database clustering.
