MGCP and H.323 on seperate FXO ports in same router?

I'm creating a testbed and need to configure H.323 and MGCP on different FXO ports within the same router. I've configured an H.323 gateway on one CCM and an MGCP gateway on another and can make calls VoIP->PSTN via both, but I get inconsistent results on which FXO port the call goes out. I've included my dial-peer config below ... is there something simple I'm overlooking? Perhaps something with the voip dial-peer?

dial-peer voice 2999 voip

description 10.41.5.30 is CCM_1

destination-pattern 2...

session target ipv4:10.41.5.30

dtmf-relay h245-signal

!

dial-peer voice 1 pots

description H.323 to CCM_1

destination-pattern 9T

no digit-strip

port 2/0/0

dial-peer voice 2 pots

description MGCP to CCM_2

service mgcpapp

destination-pattern 9T

no digit-strip

port 2/0/1

Re: MGCP and H.323 on seperate FXO ports in same router?

When using MGCP, CCM controls the dial plan, so the following commands are not necessary for the MGCP port and could be causing your inconsistencies.

destination-pattern 9T

no digit-strip

Please see the following quote from the link referenced below.

"Caution: Cisco CallManager controls all dial plan-related configuration elements. Do not configure these elements in the MGCP gateway for MGCP-managed endpoints (those with the application mgcpapp command in the dial peer statement). Do not configure any of these functions:

Under Dial Peers

destination-pattern

session target

Under Voice Ports

connection { plar | tie-line | trunk }"

If you are doing MGCP fallback, you need to configure the dialpeers with destination patterns and such.
