Centralized CUCM 7.1.3
Remote Site 2951 Voice Gateway
2 x PRI MGCP Controlled
23 x FXS Ports MGCP Controlled
Configured with CME as SRST
All FXS Ports are registered with CUCM properly and can accept inbound calls from the PSTN or from IP Phones.
However, dialing out from the FXS Ports fail becauase they are matching dial-peers that are configured on the router for SRST only. Both attempting to call an IP Phone or PSTN outbound both fail.
PSTN calls fail because it matches a dial-peer with destination-pattern 9 but the PRI port is not failover mode so the D channel is backhauled to CUCM.
IP Phone Calls fail because it is matching an ephone-dn telephony-service dial-peer configured for whatever extension I am trying to dial.
Why is an MGCP controlled FXS Port matching H323 Dial Peers when dialing out?
I will attach my configuration.
And I re-read this post:
I added service mgcpapp to all dial-peers that have a destination pattern that start with 9 and unfortunately it is still matching on PSTN calls for some reason and getting a busy as a resulte.
You want to add 'service mgcapp' to *all* POTS dial-peers, not just the ones with destination pattern starting with 9. Destination-pattern is irrelevant for inbound dial-peer matching since you have 'incoming called-number .', so it's never going to look at dest-patt off ANI for a inbound match.
If that doesn't fix it, you're hitting dial-peer 0, but I doubt that since you have 'incoming called-number .' which will match anything.
