MGCP with FXO Problems

I have configured MGCP to access an FXO port used for our paging systems.

When I dial the access code, I get the Intercom Tone briefly then the audio goes away and I am showing connected. The voice port status even shows the interface as being up. When I hang up it shows idle.

Any Ideas?

We are running 12.2(15)T on the router. 2651

Re: MGCP with FXO Problems

After alot of debugging, I found the problem, but it doesn't make sense. I had to change the route pattern to remove the digits predot.

Example *5.

It was sending the *5 to the Intercom.

Can anyone enlighten me to the below the command?

mgcp dtmf-relay voip codec all mode out-of-band

I thought this command on the router removed the digits sent to an MGCP Gateway?

If I am wrong, please explain. Any explaination would help me.

Hi Jason - we are trying to

Hi Jason - we are trying to interface with a Dukane MCS350T.    Are you still using this configuration with MGCP and FXO?  We are having similar troubles and would be interested in a config if you have something functioning.
