Re: Configure Cisco ISR 4321 to block specific incoming phone numbers

Circle · ‎03-20-2024

Greetings,

I am looking for information on blocking incoming phone numbers within our CUCM voice gateway Cisco ISR 4321.

Any examples or documentation would be greatly appreciated.

Thank you!

The internet is abundant with resources on this subject. The link provided by @b.winter includes a detailed session on Call Blocking Configuration Examples

Daniel Bosch · ‎03-21-2024

Here's a specific example I pulled from my journal to block inbound calls on POTS lines. In my case, I translated any matching number I wanted to block to '0' since there would be no matching outbound peer. You could use any pattern that doesn't match any outbound peer and get the desired result. This might work on ISDN PRI too but might the translation-profile might be applied to something different.

!

voice-port 0/1/2

trunk-group POTS

connection plar 13180184800

bearer-cap Speech

caller-id enable

!

voice translation-rule 9999

rule 1 /.*/ /0/ <-- 0 does not match any outbound peer.

voice translation-profile CallBLOCK

translate called 9999

!

dial-peer voice 9990 pots

description ### Block inbound from 512.465.1883 ###

translation-profile incoming CallBLOCK

translation-profile outgoing CallBLOCK <-- Probably not required but doesn't hurt

huntstop <-- Probably not required either but doesn't hurt

answer-address 5124651883 <-- Matches calling number you want to block

What your doing in your example here is not really what the documentation for blocking calls says. Your example is for sure not letting the call to go through, but it's doing so by no route for the called number after the translation. To do call blocking as outlined in the referenced documentation you would do this.

voice translation-rule 1
 rule 1 reject /5124651883/ ! The calling number you wand to block
!
voice translation-profile call_block
 translate calling 1
!
dial-peer voice 100 pots ! Incoming dial-peer, can be pots or voip, it doesn't matter
 call-block translation-profile incoming call_block
 call-block disconnect-cause incoming call-reject

Daniel Bosch · ‎03-21-2024

Thanks, Roger.

If I recall correctly, I wasn't having luck with what I found in documentation at the time. I may have been doing something wrong or was encountering a bug and didn't know it. I deposited your solution in my journal too, along with my 'workaround' solution. If I ever have to do this again, I'll try it the right way first.

Daniel Bosch · ‎03-21-2024

And here's an example I used with a SIP carrier. Hope this is helpful.
