Alex Balashov of Evariste Systems, active community member and contributor of Kamailio (OpenSER), running a VoIP consultancy business in USA, leads a VoIP User Conference about Kamailio, the role of Asterisk, SER and media gateways, etc.
Among topics: relationship of Kamailio to OpenSER project history, what is Kamailio (OpenSER), SIP server (for certain purposes, such as registrar, presence user agent, etc.), common uses of Kamailio, service delivery platform engineering and Asterisk scaling using Kamailio, some discussion of sip-router.org initiative.
Almost 2 hours of recording, going from overview to deep technical concepts, I can even say, a great tutorial about Kamailio in some aspects.
Evariste Systems comes with a big bag of expertise about SIP and SIP Proxy, Kamailio (OpenSER) in particular, being one of the nominations for Kamailio (OpenSER) 2008 Awards and good candidate for 2009.
