I cut our CCME environment over to a CCM 6.0 system today, and I am having a really hard time getting inbound DID working.
The CCM is connected to the PSTN with a PRI through a 2821 MGCP gateway. Outbound calls are working fine, even passing the correct CLID digits that I programmed in the External Phone Number Mask for each DN.
The problem is, I cannot get incoming calls working at all. Whenever I call one of my DID numbers, I get a canned "You have reached a non-working number" message which I think is coming from the CO after the CCM rejects the call.
I have been going through the CUCM6 System Guide and CUCM6 Admin Guide to no avail.
How do you configure incoming DID in this type of system? Unfortunately, our DID numbers do not match any digits with their extensions, so the external phone number masks are set to the DID number. This gets passed correctly as CLID on outbound calls.
Please let me know if I haven't provided enough information. :)
