that is available if you're using an H323 GW, it's not possible with MGCP.
Call Blocking Configuration Examples
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:
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.
