Hi Nitin, For reINVITE for fax, is far-end converting "m=audio" line to "m=image" ?
Can you share the SDP in both reINVITE's. Thanks, Puneet -----Original Message----- From: sip-implementors-boun...@lists.cs.columbia.edu [mailto:sip-implementors-boun...@lists.cs.columbia.edu] On Behalf Of NK Sent: Friday, July 31, 2015 11:32 AM To: sip-implementors@lists.cs.columbia.edu Subject: [Sip-implementors] SIP Reinvite after T38 Negotitaion Dear All, It is legal to send re-invite after sending T.38 when negotiation is already done. Below is the scenario. UA ---------> INVITE UA <------100 Trying UA <------- 180 w/SDP UA <------- 200 OK UA ----------> (Re-invite for fax with T.38) UA <------100 Trying UA <-----------200 OK *UA <---------- RE-INVITE wSDP G.729* *UA ---------> 488* Now after this another re-invite is coming (in green) with G.729 Codec and i am rejecting this with SIP 488. Anyone observed this kind of scenario earlier? Can you please advise and help on this. Thank you in advance.
