My original setup had the remote location coming over the wan and using our PRI's to make outbound calls. THis is a seperate company and they installed two POTS lines into their router.
I configured the router to use the FXP ports as MGCP
I configured route patterns in the CCM to do the following
1) using both POTS at the remote loaction. If they are full to roll out our PRI
This works fines, I am running into an issue where:
1) if someone makes a outbound call and goes over the pots. It connects and works. If that person were to transfer the called party to voice mail or to an IP phone at the main location. It rings, the remote location ansers and the call is sent. But no one hears anything. Its dead silence.
2) if someone calls in on the POTS lines, the remote office can answer it and talk. If the recp left her desk and it goes to voicemail (At the main location) it connects but dead silence.
I think its a codec issue but the call doesnt drop. It connects fine and stays connected.
As anyone seen this? Does it sound like a firewall issue?
I seen that, but there is audio when the local IP Phones (Local to the router with the POTS) answers. They can hear and talk fine. The problem is when that call gets sent over the wan to the vmail. Or if they attempt to transfer a call to another department (to the main site)

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
