Help with H.323 setup


I'm trying to put to work a small voip setup compossed of CCM 5.0 server and a 2821 with a VIC2-2BRI card as TE (user side) and IOS 12.4(10) but its's not working when it comes to call or receive calls from the PSTN/PBX. It seems that the Route Pattern configured in Call Manager doesn't find the gateway and

viceversa. Furthermore I'm not sure whether dial peers are working. Im' using H.323 although previously I tried MGCP also.

When I call from the IP phone no call arrives to the gateway and when I call from the pbx the call does reach the gateway but not the ip phone. The gateway looks unregister in Call manager but i think this is normal in H.323, not sure.

I attach the diagram of my setup. This is the relevan part of my configuration.

Dial-peer voice 1 pots

incoming called-number 6....


dial-peer voice 2 voip

destination-pattern 6...

session target ipv4:

dial-peer voice 3 pots

Re: Help with H.323 setup

You need to provide the gateway address in the Callmanager gateway configuration. Make sure that gateway is configured correctly.
