Do you want to block it based on calling or called information ? Is this calls Coming from a gateway or another CUCM through trunks ?

Jaime, tu respuesta no ayuda en nada. A veces debemos ponernos en el lugar del otro y solo ayudar.

Hello Roger,

Thanks.

I wrote the following if you are trying to match a specific number.
This is for ISDN configuration.
You can apply the call block treatment to a broader peer if you want too, to prevent any number from being reached.
There is administrative overhead to this, caution since you're changing the configuration of your voice gateway, and, as always when this discussion comes up, you're playing a game of whack-a-mole that you probably cannot win trying to block a caller from reaching you.
dial-peer voice 201 pots trunkgroup 1234 description Special Treatment Screening Number translation-profile incoming PSTN-Inbound call-block translation-profile incoming CallBlock_Peer_201 call-block disconnect-cause incoming user-busy incoming called-number NXXXXXX direct-inward-dial forward-digits all
The incoming called-number represents the number as it would be presented to the gateway. Noting that translations are applied after match of the peer, here we match 7 digit subscriber as presented to us for a DID.
The call-block translation-profile incoming CallBlock_Peer_201 refers to a voice translation-profile specifically for this peer. You should create your own for your own peer, if needed.
voice translation-profile CallBlock_Peer_201 translate calling 600
The above profile, named in the dial peer, tells us that we are "translating" calling numbers using voice translation-rule 600. Called party number is not relevant here.
voice translation-rule 600 rule 1 reject /NPANXXXXXX/
The above translation rule, which can contain up to 100 rules, matches a calling party number in whatever format given (number, TON, etc) and marks that call for reject.
