Block specific incoming calls on H.323 gateway

[master001]

Hi all,

I tried to block some specific incoming calls (based on calling party number) on H.323 gateway.

Currently 2 dial peers on the H.323 gateway:   dial-peer voice 10 pots & dial-peer voice 80 voip,

dial-peer 10 is translating incoming calls to 5 digit extension number,

dial-peer 80 is forwarding the calls to CUCM. 

What is the best practice configuration to block some specific incoming calls (based on calling party number)  on the gateway?

Blocking on dial-peer 10? or 80? Thank you.

You can use reject translation rules on the GW:

Hi,

Create a translation rule to match the calling number and to reject the call. Assign the translation profile to the incoming dialpeer (dialpeer 10)

voice translation-rule 200
 rule 1 reject /123456/
 !
voice translation-profile REJECT-CALLS
 translate calling 200

Thank you all.   I applied the new translation rule to dial peer 10, and it works as expected. 

If I want to block a specific incoming fax on this same H323 gateway,  any configuration to be added?

Thanks again.

it always recommended to apply rule at the beginning, you can apply the same calls hitting on first dial-peer its hitting .

Reject Calls

Use the reject keyword to reject calls that match. This example rejects all calls that start with "234".

rule 1 reject /^234/

You can test the same and verify it.

router#test voice translation-rule 10 1234
1234 Didn't match with any of rules

router#test voice translation-rule 10 2345
 blocked on rule 1
