CUCM intercept treatment catchall

[mcgeehonjp]

Is there a way in CUCM to catch un-routeable or invalid dialed numbers and either send them to an operator/DN or to play an announcement?  At the moment these types of calls just get a fast-busy.

For example, in Avaya there is an intercept treatment field that can be set to play an announcement for all invalid extensions dialed within or into the system such as re-order tone.  Similarly, when I dial a dial a 7 digit extension and should have dialed a 10 digit I can intercept this independently and relay the user to an announcement about how to dial correctly.

Does CUCM have the ability to do anything like this? I cannot figure out how to intercept incorrectly or rogue dialed numbers and route then somewhere or play an announcement.

Thanks in advance

No, there's no catch all config built into CUCM, you would need to create DN/pattern (s) based on your dial plan and dialing habits to do that.

IE if your dialing plan is 4 digits, a XXXX to catch anything that does not match anything else.

This would also require careful planning to avoid routing issues.
