Actually we did send INVITE to UA specifying both G729A and G729B. UA did not reject the Call. We configure the UA's codec to G729A and G729B separately and they worked. However, some UA may not like it.
Here is a sample SDP that specify G729A and G729B. v=0 o=root 743184990 743184990 IN IP4 10.50.10.146 s=call c=IN IP4 10.50.10.146 t=0 0 m=audio 10014 RTP/AVP 18 18 101 a=fmtp:18 annexb=no a=fmtp:18 annexb=yes a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 a=ptime:20 a=sendrecv I think G729B is G729A + VAD. Correct me if I am wrong. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Sanjay Sinha (sanjsinh) Sent: Wednesday, November 15, 2006 2:58 PM To: sudhagar NAGARAJAN; [email protected] Subject: Re: [Sip-implementors] Required SDP content for G729A, G729AB, G729B I do not think it is possible to indicate support for G729A & G729B in same offer.
