#1747 closed defect (fixed)

Bad SDP negotiator state after receiving 200/UPDATE with SDP to an UPDATE without SDP

Reported that when session timer refreshes session by sending UPDATE without SDP and then receiving 200 response with SDP, the SDP negotiator will be in a bad state (WAIT_NEGO), so that any next incoming re-offer will be rejected and any attempt to send re-offer will fail.

Original report can be found here.

Thanks Poquillon Bernard for the report.

In 4791:

Fix #1747: Don't process message body in the incoming 200/UPDATE if we don't send offer in the UPDATE. Note this also fixes another issue: session timer should always inspect 200/UPDATE response (for session refresh) regardless availability of message body.
