The one and a half day presence in Chicago was surprising good for Kamailio and SER – people started to get the real value of the project and catch up with latest features.

Moreover, the first day had a lot of presentation with Kamailio and SER (see agenda at: http://www.cluecon.com/schedule):

• Phillip Zimmermann – did his demo with iptel.org sip service
• Mahesh Paolini-Subramanya – a clould based system for telephony
• Scott Burkett – back-end platform for web telephony
• Robin Rodrigues – several nice examples using upcoming 3.1 addition: embedded http server
• Irv Shapiro – ifbyphone platform – programmable telephony applications
• I (Daniel-Constantin Mierla) ended the list (the link above), no much left for me to say , but I enjoyed chatting before a lot with folks in the breaks

Hopefully these presentations will be soon on event’s site. We will try to publish more about each one, they were interesting use cases.

Being hosted and maintained by members of our development team, the repositories are updated frequently, giving instant access to latest stable snapshots. Enjoy!

The presentation is about designing and implementation of geographical redundant Voice over IP systems with the Kamailio SIP router. It goes through an overview about the 1&1 voice over IP backend, some performance requirements for carrier grade VoIP networks and real-world measurements.

Then are some key concepts for building a geographical redundant system are presented. This are for example partitioning of the user base and network load with different means like anycast IP and means of maintaining a shared database state for subscriber data and registration information. Finally some common problems in building bigger VoIP clusters and solutions approaches are discussed.

• VoIPToday Kamailio Interview

• Goals of Kamailio, how it differentiates from FreeSWITCH and why using them together creates a very powerful framework to build large VoIP systems.
• Kamailio for sip routing and FreeSWITCH as media server (conferencing, voicemail, IVR, announcements)
• FreeSWITCH as a B2BUA for Kamailio (topology hiding, transcoding, call interrupt detection)
• FreeSWITCH as prepaid engine for Kamailio
• Load balancing FreeSWITCH servers with Kamailio
• Q & A Session

Daniel-Constantin Mierla has two presentation about Kamailio – SIP Router project:

• The SIP Router Project – Asynchronous SIP Routing
• Do your SIP routing in Lua!

First talk focuses on asynchronous processing capabilities of this SIP server and what is new in latest version:

• asynchronous TCP
• asynchronous SIP message processing
• asynchronous message queues
• asynchronous TLS
• new features in 3.0.x and devel versions

The second talk goes through LUA API exported by this SIP server, which allow building new fancy SIP applications without messing with C coding or configuration file language.

More about what is new in upcoming 3.1.0 and LUA API:

Note: Kamailio is the new name of OpenSER project, name changed on July 28, 2008, due to trademark issues. First version under Kamailio name was 1.4.0. Source code for releases 3.0.0+ is hosted on GIT repository at http://sip-router.org. Older versions will continue to use OpenSER name. Project site and SVN repository on SourceForge.net still use the old name OpenSER.
