blocking a number from being dialled outbound on H323 gateway and CUCM

[carl_townshend]

Hi all

I need to block a numberfrom being dialled from our cucm to the outside, for example the number is

112233445566

How would I do this on the cucm and h323 pstn gateway?

we use 9@ on cucm for outside calls

on the gateway we have some translation rules as below
!
voice translation-rule 101
 rule 1 /^4\(...\)$/ /594\1/
 rule 2 /^3\(...\)$/ /593\1/
 rule 3 /^6\(...\)$/ /506\1/
!
!
voice translation-profile PSTN-OUT-1-0
 translate calling 101

!

voice-port 0/0/0:15
 translation-profile outgoing PSTN-OUT-1-0

Just put a specific route pattern in CUCM for the numbers and block there.
9112233445566
Under Route Option chose Block this Pattern

On CUCM, either a TP or a RP can be used for a call block. On the IOS, you can create a translation as follows -

voice translation-rule 1
rule 1 reject /112233445566/

voice translation-profile CALL-BLOCK
translated called 1

dial-peer voice X voip
call-block incoming translation-profile CALL-BLOCK

You will always have to apply the call block on an incoming dial-peer. You might need to do a "debug voip cc inout" to see the incoming dial-peer for these calls. Alternatively you can use a "show voice call status" to get the dial-peers.
