[SIPForum-discussion] Regarding 183 Session Progress with SDP

Fri Nov 8 12:34:37 UTC 2013

Hi Team,

I've a scenario where UAC is not acknowledging the SDP in 183 Session Progress  sent by UAS (200 OK followed by 183 progress does not have any SDP). I noticed that the 183 Session Progress does not have any session header as specified by draft RFC http://tools.ietf.org/id/draft-ietf-sip-183-00.txt.

Who is wrong here UAC or UAS?

Thanks,
Keshav
