Hi, could you explain the exchange of sdp information in sip signalling? I got two UAs: UA #1 sends an INVITE to UA #2 without message body UA #2 replies attaching a SDP message body
Can UA #1 launch an instance of VLC (passing it the SDP file) and receive streaming media by RTP?
Is it correct as a media request scenario?
Hi,
if the INVITE doesn't include a SDP message in its body, then UA #2 replies
with a 200, attaching
a SDP with the full codecs list. This final response needs to be
acknowledged by UA #1
with an ACK request that includes a SDP message with the negotiated codec;
then you can
establish a RTP session.
