I feel like B2BUA should offer g729 as it's ( as B supports g729) preferred codec anlong with any other codec B support, then let C decide which one to answer.

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 ________________________________ From: ABHISHEK GUPTA [mailto:[EMAIL PROTECTED] Sent: Friday, October 03, 2008 11:51 AM To: Sarkar, Uttam Cc: [email protected] Subject: Re: [Sip-implementors] help yes u r rite that B2BUA will do transcoding , but my scenario is As call Bs, As Refers Cs; A-B is G711U-G729 and B-C is pass through (G711U) so is the above given scenario is possible. 2008/10/3 Sarkar, Uttam <[EMAIL PROTECTED]> In your call flow I see A sents call to B2BUA with g711, B2BUA sends the call to B using 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.
