As we have already seen it before , if the voice gateway is unable to match an inbound leg for the call , your call will take the properties of the PVID0 .
Don’t forget that you can’t update any properties if the PVID0 is hitted .
Let’s review then the specificities of this default dial-peer:
For POTS dial-peer
- No IVR applications possible
For VOIP dial-peer
- Any codec
- fax-rate voice
- ip precedence 0
- No Resource Reservation Protocol ( RSVP)
- VAD enabled

During WAN failure , we can observe that H323 will not preserve absolutely the call when the failover occurs as there is no more any signal from the CUCM.
An unofficial workaround is to use the command h225 timeout to suppress the keepalive between the Call Manager and the gateway.

no h225 timeout keepalive
