That's a global Call Blocking for all incoming calls from the PSTN, but it's possible to made this on the CCM?

I mean, that in a single IP Phone or in a group of them, I can block or let pass calls an incoming call considering the caller number.

decisions made on the calling number can only be made on the GW using H323, the CUCM does not have this capability



if this helps, please rate

ok, but with other products like Personal Communicator and Unified Presence, it is possible to implement black/whitelists?

I've not found that those product provides this feature, only a test documents that mention this:

Case Title

White list/Blacklist Creation by Unified Presence Server End User


Verify that a whitelist and a blacklist can be created by a Unified Presence Server end


Call Component Flow

Unified Personal Communicator->

Unified CM->Unified Presence->

Unified Video Advantage

But that doesn't appears on data sheets or presentations for these products.
