Hi everybody, I am implementing SIP, SDP and RTP as a course project. I would like to know if there are any *free* SIP implementations so that I can test my implementation. I tried couple of implementations listed on columbia.cs SIP web site, but they donot do media transfer once the call is established (they just have SIP and SDP). For my project, I will be using microphone and PC speaker as input and output for audio and platform is Solaris. It would be great if somebody can help me. Thanks, Sarat.
