"Some" international calls failing...

phoeneous

Scenario: Two international calls are being placed, one works and the other doesnt.


Telco is pointing fingers at me (as usual) but I don't think I'm at fault. They're saying that the call that fails is because I'm sending the 011 prefix AND the international bit. wtf is the international bit???


Both numbers are being placed from the same phone and both numbers are matching the same route pattern in cucm. Then at the h.323 gateway, both numbers are matching the same dial-peer which is:

dial-peer voice 24 pots
 description ***Intl***
 destination-pattern 011T
 prefix 011




sh dial-peer voice 24

Any thoughts?

can you run debug isdn q931 when you try those test calls, just to be sure that you know the digits you're sending to the telco?

if you are sending the international TON the call will fail. Most carriers do not accept the international TON unless its been worked out with them before hand.

Put this command on your PRI

That command worked, thank you.
