I have a Callmanager 5 based VoIP deployment that is about 99% complete with about 15 locations. Each of these sites sits in a couple of local calling areas and utilize 4 PRI trunks for all inbound/outbound calls (all sites connected via Metro Ethernet LAN or private fiber network). Each site has a 2800 series router with FXO card and configured as a basic MGCP gateway for handling 911 calls out the local office so 911 service gets the correct physical address of that office. Other than that, I don't have much experience setting up voice gateways using FXO. I have this one remaining office which is on the MetroE LAN and can get to our PRI gateways, but their local calling area is outside of the other groups and uses a small-town Telco, so they can't route their local calls to our PRI gateways (and their local public number needs to remain the same and tied to that Telco). So, I put two 4-port FXO cards in their 2801 to handle their 6 POTs lines, and set it up as a MGCP gateway. Then I discovered inbound caller-ID doesn't work with MGCP gateways and FXO ports and that you need to setup as a H.323 gateway. I would love to see some sample configs on how to go about doing this.
The only outbound calls on these FXO ports will be the ones with a dial pattern 9846xxxx, which is their local prefix, and of course 9911 for 911 calls. Everything else should route out our PRI gateways. I have made the necessary route patterns in Call Manager and will point the 9846xxxx to the H323 gateway I setup in CM as well. I'm just not sure how to setup the H323 stuff in IOS on the router or create the appropriate dial peers for inbound calls coming to the POTs/FXO ports at the local site.
Any help greatly appreciated. This is the first time I believe I have posted (at least on this username, lost my username before and only posted once) but have used Tek-Tips many many times to gain lots of useful answers to other problems! thanks
