Hello,
this Friday, March 19, late afternoon, the weekly VoIP User Conference is hosting a session about SIP Router project. My goals are to present the achievements so far within SIP Router projects, what is new in Kamailio 3.0 release and plans for the future.
More details can be found at: http://www.kamailio.org/w/vuc-the-sip-router-project/
You can join the audio conference via sip, skype, pstn line or other several options presented on http://vuc.me site. There is a irc channel available for it: #vuc on irc.freenode.net.
Cheers, Daniel
