Core Issue

The calling party is video enabled (IP phone with Cisco VT Advantage [CVTA]). The calling party and gateway are in different regions, between which the Video Call Bandwidth is set to None.

Resolution

For a workaround, issue the bearer-cap speech command on the voice port.

Note: This command forces the calls to use audio only, which allows the calls to work. This bypasses the bearer capabilities mismatch.
