Dial Peer Matches but Outgoing Calls to PSTN through FXO fail on voice gateway
I have an issue with a voice gateway config
We have a SIP Trunk configured from CUCM to a 2811 Gateway with 2 FXO Ports.
Incoming calls on the on the PSTN are routing correctly to CUCM
Outgoing calls from CUCM to the PSTN are failing, when attempting the call the phone give as a fast busy tone.
From doing a "debug voip dialpeer all" I can see that the calls are coming over the sip trunk and matching the dial peer on the GW. I am using 1471 (which is a routable pstn number in the UK) to test this specific gateway
I have attached the running config of the gateway and a copy of the debug
