A new project was released to the public on the 29th of January, 2008. Adrian Georgescu of AG Projects announced the version 0.9.1 of MSRPRelay, an Open Source implementation of IETF standard RFC 4976. MSRP relay is an extension to the MSRP protocol (RFC 4975). Its main role is to help NAT traversal of Interactive Messaging and file transfer sessions for SIP/MSRP endpoints located behind NAT.
Out of the box, the software is designed to work in combinations with the
subscriber database used by OpenSER.

Fall Boston 2007 Follow Up
Another major VoIP event just ended. Time spent there was too short, or I was too busy in those few hours I could roam freely to get the real pulse of the show. The next day was full for me with the OpenSER Admin Training Session and BoF.
Those interested in the materials, follow next link and download the slides from the course of BoF session:
http://www.openser.org/events/2007-VoN-Fall-Boston/
Beside OpenSER-dedicated day on the 1st of November, I attended the "Asterisk & OpenSER: A balanced network strategy", part of the Digium Asterisk World, and I was pleased to see large interest in using the two applications together. It is clear to more and more people that the two are completing each other, not competing. The efforts to make the integration easier show now the results.
As usual, several active members from the community showed up, being nice to associate names with faces and chat a bit.

Berkely DB Support
Courtesy of William Quan, of CISCO Systems, a new DB module has been submitted to the trunk that incorporates the Berkeley DB into OpenSER. This module depends on Berkeley DB, which is a high-performance embedded DB kernel.
The Berkeley DB offers a couple of architectures:
1. Concurrent Data Store (CDS)
2. Transaction Data Store
This module uses the CDS model. One of the main differences between these architectures is DB recovery and robustness (Please refer to the Berkeley DB for full details). In a nutshell, the onus of recovery is on the application (e.g. openser). This modules contains a recovery program utils/db_berkeley/bdb_recover that can be used to recover DB files.
Like other DB modules, the DB must be created before OpenSER can be started. The standard openserdbctl script can be used to create the DB once the Berkeley DB is installed.
See the readme file for db_berkely module and the news at openser site.

Freezing in one week for 1.3 release
Time to prepare a new major release for OpenSER is approaching. In about one week the code will be frozen, as we plan to have next major release 1.3 out in November-December time frame.
It is the time to do the commits of the features you want in 1.3. To list what other important changes happened in this respect within last weeks:
- refurbishment of the pseudo-variables allowing to access AVPs and headers with a dynamic index
- "while" statement allowing to iterate through the AVPs/headers
- usage of special processes in nathelper to send keepalive NAT pings, improving a lot the scalability

OpenSER Admin Course and VoN Rome 2007
I hope it is general opinion that the OpenSER admin course at VoN Rome was successful. The room was full, about 35 attendees. Time was pretty short to get deeper in OpenSER configuration tricks, but should give the base of knowledge to build proper and well-designed VoIP platforms using OpenSER.
It started with introduction of configuration file architecture, going through common components of it, touching the very important aspects of a VoIP environment: NAT traversal, accounting, authentication and authorization, load balancing and high availability. The last topic of the tutorial was integration with Asterisk media server, towards a lot of good steps were done in the past for a straightforward solution.
The day ended with an open discussion, revealing hot questions about DNS balancing and black-listing, NAT traversal, present and future of the project.
VoN Rome itself was pretty well represented by the local market, with nice SIP-enabled video solutions for security and surveillance at Video on the Net section. Otherwise, usual debates SIP-P2PSIP-IMS, etc. Personally I have met for the first time a lot of people using OpenSER, also meeting old friends (e.g., Andreas of sipwise.com, Georgios, Federico, Adrian, ...) from the past events.

New enhacements during end of August - beginning of September
H350 is a new module that follows ITU H350 recommendation, contribution by University of North Carolina (module's readme). From 1&1 Germany came the carrierroute module, targeting large scale deployments, allowing all in one routing, balancing and blacklisting capabilities, from a config file or a database source (module's readme).
Still in scalability area, OpenSER allows to start timer processes on demand, improvement that will open the door to better performances in handling nat traversal at signaling layer, with a single OpenSER box.
Not the least, the launch of OpenXCAP contributes to complete the components required to implement a full SIP-based presence service.

SCTP and Config Benchmarking
Two of the newest additions in OpenSER development version got the attention in the last time.
First is about SCTP (Stream Control Transmission Protocol), a contribution of Connecticut College, completes the list with transport protocols supported by OpenSER. SCTP is mainly used for trunking, hopefully will gain more space in end-user side as well.
http://www.openser.org/mos/view/News/NewsItem/SCTP-Support/
Second is about benchmarking your configuration file. The new module benchmark brings the necessary tools so you can wrap a piece of configuration file and get the execution time. Elements that can have decisional impact in scalability and tunning.
