Dear All, I am facing the issue with my SBC, where my source is sending me the complete list of RTP payload and my SBC is returning back 488 Not Acceptable here. v=0 o=BroadWorks 148094714 1 IN IP4 209.58.101.249 s=- c=IN IP4 195.189.150.38 t=0 0 m=audio 6300 RTP/AVP 18 0 8 35 36 2 38 39 40 41 42 43 44 45 46 47 4 80 3 56 118 101 a=rtpmap:118 G729B/8000/1 a=fmtp:118 annexb=yes [US] Isn't payload type 18 specifies that g729. Why payload type 118 is doing the same. a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=rtpmap:120 no-op/8000 [US] I don't see any reference of 120 in the m line. Your SBC should choose the codec from the list and answer the call with that codec. Now when i checked the IANA RTP payload list, and observed that most of them are still unassigned. Could anyone please check the above SDP and payload...and please help me whether it is correct to send 488 to source...or not. And also if anything wrong in above, so please pinpoint it. I also feel that because of this CODEC packet size is increasing and causing the issue.
