1) You can block based on Calling Number on CUCM or ON Voice Gateway
Refer below for CUCM

I would suggest using the Voice translation rule for minimum impact

Hi,

Yes, you can block it on Cisco Voice Gateway. In all the Cisco routers you need to apply the translation rule, profile and apply to incoming dial-peer pots / voip. Pots in case of PRI and VOIP in case you have SIP trunk.

STEP-1

voice translation-rule 1234
rule 1 reject /^1234567888/

rule 2 reject /^1234567999/

rule 3 reject /^1234567000/

STEP-2

voice translation-profile blockincalls
translate calling 1234

STEP-3.

dial-peer voice 444 pots
description Incoming call from PSTN
call-block translation-profile incoming blockincalls

If in case of SIP TRUNK,

dial-peer voice 4444 voip

description Incoming call from PSTN
call-block translation-profile incoming blockincalls

Wish I answered your query.
