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

I have seen the similar issue with a Polycom video phones. By the time Polycom fixed it, we were just ignoring the duplicate payload number to have a+v call. Thanks, -kashif *"All you need is ignorance and confidence and success is sure."* -Mark Twain On Tue, Sep 18, 2012 at 10:39 AM, Gaurav K

[Sip-implementors] 405 response for UPDATE

2012-03-21 Thread Kashif Husain
Hello SIP implementors, I have a far-end entity which sends UPDATE in Allow header but when I send UPDATE for session refresh I get 405 Method Not Allowed. Is this a valid behavior? Is it allowed to send 405 in this scenario? If yes then I would like know the reason behind it. Thank you very muc
