You can check for SDP version of re-Invite, if its same as previous one then its usually intended for session refresh. Thanks, -kashif On Tue, 24 Sep 2019, 02:30 Sundbaum Per-Johan (Telenor Sverige AB), < per-johan.sundb...@telenor.se> wrote: > Hi ! > Can anybody help me find relevant RFC/other

RFC 4028 describes Session Timers in SIP. RFC 3264, 4317, 4566, 6337 describe SDP as well as SDP offer/answer model. RFC 6141 describes Re-INVITE and Target-Refresh Request Handling in the Session Initiation Protocol (SIP). Hope this helps ___

2008-01-16 Thread Brett Tate
Now my question is, since UAC has clearly set the MinSE(900) andSE(900) values in the Session-Refresh request and chosen UAS as the refresher in the process, is UAS allowed the latitude to INCREASE the value of Session Expires header to 1800 in the response to Session-Refresh request?
