How to block calls by calling ID using MGCP Gateway?

[angelsor@cisco]

Hello!

How Can I block incoming call for specific calling ID in Call Manager 12.5? I am using MGCP gateway.

William Bell of the Chesapeake NetCraftsmen wrote up a wonderful how-to for this a bunch of years ago. He is using CUCM 8.6 as an example (which was current when he wrote it) but the technique holds just as true for current versions of CUCM. There used to be a doc written by him on Cisco's website as well (with the same technique) but I can't find that.

Hello Maren!

Thanks for your answer! 

I tried that procedure but the version CUCM 12.5 doesn't have the option Route Next Hop by Calling Party Number.

CUCM 12.5 absolutely does have the Route Next Hop checkbox on Translation Patterns. Here is a screenshot of a 12.5 system in my lab:

This document by @dakeller outlines how to achieve what is asked about and from what I know is what others possibly have based their posts from.

Blocking Calls Based on Calling Party ID

Hi,

You can do this using translation patterns on CUCM or translation profile
on MGCP gateway.

Here is a doc for CUCM

Here is how to do on voice gateway.

I prefer CUCM to keep single point of control of call routing.

The last option, aka on the voice gateway, does not work with MGCP. The gateway needs to be either controlled by SIP or H.323 for this to work.

It does if the rule is applied to voice port which I would do but not on
dial peers for mgcp. Good catch

Thanks for sharing @Mohammed al Baqari

Did not know that it would work if put on the voice port(s).
