I have Call Manager 4.3, Cisco camera II, IP Phone 7911, Cisco Unified Video Advantage and Gateway 2811 with PRI ISDN.
When I call inside my company all is OK - audio and video call is successfully.
When I call outside from my IP phone 7911(outside my company) I get a bysy signal.
If is not running Cisco Unified Video Advantage outside call is successfully.
What is solution for this trouble?
