Block Malicious Calls (CCM4.1)

[johnson_cheng]

Does Callmanager have a feature to block malicious calls,based on the calling number? If the answer is yes, how can I do the settings?

[Aaron Dhiman]

If you want to block DNIS, it is easily done from the CallManager:

Create a Route Pattern that matches what DNIS you want to block, then set it to "Block this Pattern".

Yes, that I know. However I want to block an outbound call originating on the H.323 gateway....bypassing the call manager completely.

[Aaron Dhiman]

Yes, you can still do that. You just need to apply the "call-block" to the inbound dial-peer, not your outbound peer:

voice translation-rule 101

rule 1 reject /9xxxxxxxxxx/

voice translation-profile TEST-BLOCK

translate called 101

dial-peer voice 1000 voip

call-block translation-profile incoming TEST-BLOCK
