Hello,
I thought it is an useful information to announce here that the SIP Communicator SIP softphone was renamed to Jitsi. There are several pages mentioning Kamailio and SIP Communicator out there, among them our participation to Google Summer of Code 2010 as well as the full SIP SIMPLE Presence configuration with XCAP: * http://asipto.com/u/sp
To fetch the latest version of this sip softphone you just go to: * http://www.jitsi.org
Btw, Kamailio is participating again in GSoC, the 2011 edition, together with Jitsi project -- I will make another message regarding this subject.
Cheers, Daniel
