I am having a problem that I can't get my head around. I'm pretty new to CUCM so forgive me if this sounds a bit basic.
I have 3 PRI circuits 1 with BT, 1 COLT and 1 C&W.
I need to prefix any dialed number that goes over the BT circuit with the 1840 number for billing purposes. The other circuits do not need this number.
We use short code dialing at our offices when we want to dial a US number its 5 and the rest of the world is 8.
The route of the problem is as follows:
I have many route patterns take the following:
I discard the digits pre dot and add the following number 001416874 to the Prefix Digits (Outgoing Calls) section. I point this to a route list called TEST. TEST points to 3 route groups with each provider defined in an individual route group. At the route group details level for the BT circiut I need to prefix the 1840, however this overwrites the 001416874 I defined earlier. How do i implement this is number 1 to get the 1840 only for the BT circuit and 2 adhering to best practices.
