As per your call flow B supports g729 not g711. So, even B2BUA can try ot make call to C (INVITE without SDP ), C could offer g711, but B may not answer with g711 as it supports g729

Do you mean that B2BUA is doing the transcoding from g711 to g729 and vice versa? If B2BUA doing the transcoding, then it can send call to C with g711. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of ABHISHEK GUPTA Sent: Friday, October 03, 2008 4:33 AM To: [email protected] Subject: [Sip-implementors] help hi, in a call scenario where B2BUA is involved, A call B.
