Block the specific number about external incoming call for specific Directory Number

[wilsonsant]

Hi Guys,

The Customer have the solution with CUCM 11.x and H323 Gateway. He would like to block the external incoming call (PSTN specific number)  for a one specific directory number.

Example:

External Number YY112166xxxx

Directory Number 7xxx

The Customer need that only the directory number 7xxx reject call of number YY112166xxx. Is it possible? 

Thanks,

Wilson

Yes, this is possible. How are calls being routed to 7xxx? Direct dial to an external number or through an operator. If direct dial, use a voice translation rule on the gateway to block the call. Apply the translation profile to an inbound dial peer specific to the DID for this extension.

Hi Brandon,

Thanks lot for Your contact and sorry by delay in answer. I read the procedure, is clear for me who to configure for all Directory Number reject the specific external number call, but, I don´t understand who to do for specific directory number. Do You have any models for pass to me, please.

Thanks,

Wilson

Here's an example:

voice translation-rule 1
rule 1 reject /1121161234/

voice translation-profile call_block
translate calling 1

dial-peer voice 1 pots
call-block translation-profile incoming call_block
call-block disconnect-cause incoming call-reject
incoming called-number 7000

This assumes your carrier is sending 4 digits for called number
