I'm having the same issue
Did you guys find a fix for this? I’m having the same issue. When I call from one Vantage phone to another, I get “Escalation to Video Failed”. Audio calls work, but the video does not.
Vantage basic 2.0.0.0.0411
IP codec set: allow direct-IP multimedia? Y
Signaling group: IP Video? Y
