Hi,
I am newcomer in SIP and Kamailio Wold an have a question.
I have two IP Telefones and would like to realize with Kamailio an IP Communication. The Problem:
a. The UA 1 calls UA 2 b. UA 2 start recording the video form UA 1, before a SIP call is established (early media)
early media is the other way round, from UA 2 to UA 1. UA 1 starts sending media (audio, video, whatever) when it receives 200 OK with SDP answer from UA1 - before it could not possibly know where to send media to, what codec etc.
183 reply usually has the sdp of callee, therefore the caller can send rtp. Or am I missing something?
can, but does usually not do.
It also does not make sense to not setup the session, if you do want to have the session.
