[cisco-voip] Inbound call on FXO uses dial-peer for PRI port - MGCP

[Erick Bergquist]

Having issue with 12.3(11)T7 on 1760
MGCP w/CCM 4.02a

On inbound calls to analog FXO lines, the call rings
once and then fast busy. The calls work fine as long
as we don't have dial-peer in router for PRI port
which is for fallback mode.

This is what is 'show call hist voice brief':

1328 : 278 10488200ms.244 +-1 +10260 pid:1109 Answer
1234567890
dur 00:00:00 tx:0/0 rx:0/0 2C (no requested circuit
(44))
Telephony 3/0 (278) [3/0] tx:0/0/0ms None noise:0dBm
acom:0dBm

Notice the pid is of dial-peer with pri port which has
direct-inward-dial.. so it should not be hitting this
at all. If the dial-peer is removed it works fine,
call completes. If it is put back with same id or
different id the same problem occurs. on the peer for
3/0, tried it also with the incoming called-number and
without - same thing. I have not seen this dial-peer
behavior before on inbound calls where they terminate
on a dial peer that is for another port. Have other
sites with same cfg working fine. Have rebooted router
also and no changes.

CONFIG for involved dial-peers:

dial-peer voice 999130 pots
application mgcpapp
incoming called-number .
port 3/0

dial-peer voice 1109 pots
destination-pattern 9[2-9]......
direct-inward-dial
port 1/0:23
forward-digits 7
