Daniel-Constantin Mierla will give a presentation about using Kamailio and FreeSWITCH together to build large unified communication platforms at ClueCon 2010. While the primary communication channel these days is voice, instant messaging and presence gain more users day by day.

ClueCon is an annual 3-Day Telephony User and Developer Conference bringing together the entire spectrum of Telephony from TDM circuits to VoIP and everything in between. The event takes place in Chicago, IL, USA, during August 3-5, 2010.

Henning Westerholt will talk about Geographical Redundant VoIP Sytems with Kamailio, on Wednesday, June 9, 2010, 11:20am, at LinuxTag 2010, in Berlin, Germany.

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.
