Re: [Sip-implementors] Query on SIP 488 response

It is understood that the terminating device does not support any of the codecs that the incoming INVITE has. this issue occurred when a landline called VoLTE device and the intermediate MSC/MGCF translated the SS7 message to SIP INVITE and put the codecs it supports. So since the terminating device does not support any of the listed codecs in SIP INVITE SDP offer, it responded with 488 response So my query is - is there a way the terminating device could indicate the list of codecs it supports in 488 response? RFC3261: 21.4.26 488 Not Acceptable Here The response has the same meaning as 606 (Not Acceptable), but only applies to the specific resource addressed by the Request-URI and the request may succeed elsewhere. A message body containing a description of media capabilities MAY be present in the response, which is formatted according to the Accept header field in the INVITE (or application/sdp if not present), the same as a message body in a 200 (OK) response to an OPTIONS request.

Isn't this what late offers are meant to accomplish? Empty (no SDP) INVITE --> <-- 200 OK with SDP offer end-to-end ACK with SDP answer --> -- Alex On Sat, Dec 14, 2019 at 11:31:50PM -0600, Ranjit Avasarala wrote: > Hi > I have a scenario where the terminating device responds with SIP 488 Not > Acceptable here response.
