Routing call to PSTN via CUCM7

Eric.Biggie · ‎06-06-2010

Hello all,

Can someone please help me get outbound calls routed out to my PSTN. I've tried using MGCP and now H.323 and it still doesn't work. I've been able to route an inbound call to one of my IP phones but I had to use "connecton plar 7001" to even get that far. When that's not in my running config, then an inbound call won't even route to call manager? All of my internal IP phones work fine. I can dial internally with no problems. The gateway (currently H.323) is communicating with cucm7. The route pattern is configured for 9.! with pre-dot selected and then the route list and group tunnels down to my H.323 gateway device. I don't what I'm missing? My Call manager is 172.30.100.14, and my gateway is 172.30.100.51. I have 4fxo ports 1/1/0 to 1/1/3. here's my gateway running-config:

Any help is much appreciated. I just want to get outbound calls working.

Thanks,

Eric

If your CUCM config is correct then do a debug ISDN Q931 and debug voip ccapi inout to further troubleshoot this in the GW.

Couple of things:

1. CUCM may be waiting for you to enter more digits before sending the call to the gateway since the last criteria you are matching in your route pattern is "!". I think your route pattern would match all numbers in the range 90 through 9999999999999999999999. If you want to test this theory then put a pound sign (#) at the end of your route pattern. Then on your route pattern discard pre-dot and trailing #. Then dial your PSTN number followed by the pound key.

2. If you are stripping your external access code 9 (pre-dot) then you are not sending the "9" to the gateway (unless you are prefixing a 9 on your route pattern). Your POTS dial-peer is matching 9T. If you are not sending the 9 it won't match your POTS dial-peer.

Also, since you have more than one active IP Interface you may want to force h323 to be bound to the address you have configured for the gateway in CUCM:
h323-gateway voip interface
h323-gateway voip bind srcaddr 172.30.100.51

The debug voip ccapi inou should be helpful once the call gets to the gateway.

Joel,

Thanks for your reply, and sorry I'm replying so late. My day job keeps me really busy.

I eventually got it to work to where I can make outbound calls and receive inbound calls. I had to config the ports for PLAR on the gateway to get the inbound routed, and strangely I have to dial a "99" to make an outbound call. So far I only have one route pattern identified and its "9.!", so I don't know why I have to dial "99" to get an outside line.... but at least it works!

However, my directives have recently changed. Now I need an outside line direct to each IP phone and I need to use a prefix to only dial dn's inside the network. Each IP phone needs to act like it's just a normal phone with it's own PSTN line. I've done a little research so far when I've had time, and this looks possible.....

Thank you for your helpful reply!

Best,

Eric

PS: and Thank you, java, for your reply as well!

If you are willing to do a test, I think if you change your route pattern so that you are not stripping the pre-dot you should be able to just dial one 9 for outbound calls.
