Dear All, I have one call scenario where my termination is sending the SDP in 183 as well as in 200 OK also. As far as i know if we are getting SDP in 183 session progress then my UAC can ignore the SDP in 200 OK. Also most of the time SDP is same.
But here i noticed the slight difference of "Session Version". Here when my termination is sending 188 Session Progress with SDP is sending the SDP as below. I can see that my Termination is incrementing "*Session Version*" for SDP in 183 & 200 OK in same dialog.. *183 with SDP* S_OWNER : o=TLPMSXP2 22660 *22660* IN IP4 69.90.230.210 S_NAME : s=sip call S_CONNECT : c=IN IP4 69.90.230.217 TIME : t=0 0 M_NAME : m=audio 59072 RTP/AVP 18 4 8 98 200 OK with SDP: S_OWNER : o=TLPMSXP2 22660 *22661* IN IP4 69.90.230.210 S_NAME : s=sip call S_CONNECT : c=IN IP4 69.90.230.217 TIME : t=0 0 Could anyone please let me know if that is okay to increment the session version and if any supported document is there?
