I had an authorized CPC support contacted me. I sent them a debug log, and phone configuration. It appeared my dialplan, and phone configuration are correct. Here was their reply:


It looks like the Samsung PBX does not support video so it is rejecting the call instead of just leaving video codecs out of the caps exchange.

Fortunately, there is a way around this. We can disable video on line 2 so the phone will not send video codecs in the caps exchange. The parameter for this is reg.2.video.enabled="0"


I'll get my customer to make some test calls, and I'll keep you guys post it.
