Use two incoming dial peers with

With answer-address command

First dial peer set the answer address to match the range you have then send it to cucm over VoIP dial peer

Create another dial peer that match any other number using the command answer-address .

And use a translation rule to reject the call

Good answer! But if we wanted to NOT discard the call coming from the invalid Calling Party Number, but instead translate it to the main trunk number?

You you match the source with a specific dial peer then you translate it to whatever number you like or reject it

To do this create tow inbound dial peers first one with answer address command that match you range without changing anything to the calling number

The second inbound dial peer has the answer address with the dot to match anything else

Answer-address .

And here apply a translation  Rule to change any calling number to the number you like

For example

Voice translation-rule 1

Rule 1 /^.*/ /12345678/ this to replace any number with 12345678

Voice translation-profile p1

Translate calling 1

Dial-peer voice x

Answer-address .

Voice translation-profile incoming p1
