I have following Session Timer related question: >From the following excerpts from section 10 of draft-ietf-sip-session-timer-09, it seems session timer continues to run even if a 422 is received. "Note that only a 2xx response to a session refresh request extends the session expiration. This means that a UA could attempt a refresh, and receive a 422 response with a Min-SE header field that contains a value much larger than the current session interval. The UA will still need to send an session refresh request before the session expiration (which has not changed), even though this request will contain a value of the Session-Expires that is much larger than the current session interval."
Scenario: Received non 2xx response to re-invite How is the Session Timer managed when a non 2xx response to a refresher re-invite is received/sent that does not terminate the call? In this case the the non 2xx response(e.g 488) does not terminate the call, the call/session should continue. Only a 2xx response extends the session timer, then should a non-2xx response terminate the session timer and re-negotiate it again. What should be the actual behaviour? Thanks.
