We are trying to convert our phone setup from MGCP to H.323 gateways in order to get our caller ID on incoming FXO ports to work. (We know this isn't supported under MGCP yet.) I am trying to locate documents to help us reconfigure but I'm running out of ideas. The docs on CCO show us how to add all the dial-peers and how to add the gateway to CallManager. However, when I do, the CallManager shows the gateway as "Unregistered." Having never seen one of these in operation, I don't know if it should be doing that or not.
On the plus side, I can make outbound calls from our IP phones out through the FXO ports. No calls are coming back in, however, and none of the FXS phones on the same gateway can call into the IP phone system.
Can anyone direct me to more helpful documents to figure out how CCM and the H.323 gateways are supposed to play together?
The CM will always show unregistered for H.323 gateways. This is because H.323 does not have a conecept of registration.
It sounds like you are pretty close. Do you have a dial-peer voip?
This is the dial-peer that sends calls from your fxo ports to CM. Since each FXO port is a particular number, the destination pattern should match the DN of the IP phone the calls should be sent to (or autoattendant).
The other thing you need is connection plar on the voice-port. "connection plar opx " The number should match the destination pattern in the voip dial-peer you configured.
Thanks much for the info about the "unregistered" comment! It's nice to know whether something you're looking at is a problem or not.
I do have dial peers. Here's what I have on the router now. (I've only included the 1 interface and the voice info:)

There are 2 analog phones on the FXS ports 1/1/0 and 1/1/1, ext. 2001 and 2002 respectively. From those phones, I can call out of the FXO port on 1/0/1 and to each other. I can't call in to any of the IP phones. (Extensions 1xxx.) The IP phones can call out through the FXO port, but can't call either of the analog phones on the FXS port. I've tried adding those 2 phones in as H.323 clients but I can't see where to add in the IP of the gateway to direct the traffic.
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
answer. Be sure to read the whole thing or e...
