Travelling, so email responses may be slow!
Sorry, wrong info sent out. The OLCRej was for the OLC extended video from Opal and was rejected due to insufficient bandwidth.For the OLC extended video from Polycom with Session ID 0, now OPAL sends out OLCAck with Session ID 4.
Earlier it was an OLCAck and Session ID was set to 1.
So this will prevent the Gatekeeper to associate the Session 1 audio details with the extended video.
