CUCM integration with CME via H323 gateway

Hello All,

I am working on integrating CUCM latest version to a router that has CME running on it. All the CSSs are setup on the CUCM, the gateway is listed and the DNA shows the routing working fine on the CUCM side, to the gateway.

The gateway is where I am having the problem. I can make calls from the gateway via any extension that is still on CME. Besides the fact that I am getting on way voice.

Its trying to get calls from CUCM to CME where the problem is. The calls get out from CUCM to the CME, as I can see from the logs:


6720311: Sep 22 10:56:26.410: h323chan_chn_accept: Local(0x0) accepts TCP conn from (IP OF CUCM)(0xC0A86306) port (56414); fd=2changing from LISTENING state to ACCEPTED state

Then that's it. I get a "Your call cannot be completed as dialed..."

I have also found via h323 gateway command:

Here is the dial plan on the CME:


dial-peer voice 3000 voip

destination-pattern 3000
session target ipv4:CUCM address
incoming called-number 7
voice-class h323 1
dtmf-relay h245-alphanumeric
codec g711ulaw
no vad

Currently I don't want all calls sent to CUCM since I am migrating over.

Thoughts?

Thanks!
