Hello. I've searched for an answer to this question, but haven't found much written for UCCE surprisingly. Perhaps I'm searching for the wrong terms. This is a very common problem I've run into before with other voice systems, so I'm sure someone has a solution or two. I'm trying to find the best solution for UCCE 11.5. We have a large organization with 50K telephone numbers. 1-2% of these phone numbers are routed by an SBC via SIP to a UCCE ingress ASR gateway which directs the call to CVP using dial-peers. When the telephone number is appropriately configured in the UCCE Dialed Number / Script Selector List, everything works as designed. The calls are sent to the appropriate script and answered by CVP.
Surprisingly for such a large organization, occasionally the SBC will become configured to route a telephone number to UCCE as described above, but the telephone number is not configured in the UCCE Dialed Number / Script Selector List. This can be for a variety of reasons:
- Typically a new number is requested and the SBC programming completed before the UCCE Dialed Number is added.
- Or, an an existing number isremoved from UCCE Dialed Number / Script Selector List before the SBC programming is removed.
Either way, a SIP INVITE method for the telephone call is sent to the ingress gateway and offered to CVP. Router is unable to find a match for the dialed number, and the route request ultimately fails, which is appropriate but generates several errors in ICM & systems upstream. At this point, what is the best way to default route such calls to unassigned Dialed Numbers to an ICM script which would say, "You have reached a non-working number at UCCE..." ? We would keep an eye on this call type to understand when the default routing occurs.
This would be simple to do on CUCM and Unity Connection, but please assume we do not have CUCM and Unity to use for this example. Is this what the Default Routing tab on the PG Explorer can be used for? I'm trying that solution in a lab environment, but I'm curious if that is the traditional solution for the experts.
Thank you!
Tony
