Blocking inbound calls based on ANI

Unanswered Question
Oct 23rd, 2007

I understand that I can't block a specific number from calling in to our office if I'm using MGCP on my gateway.

I called my telco and the guy in their service department said they can't block calls based on ANI on PRI's or associated DID's He said they could only do it on regular analog business lines. ie: "FL1"

I find this hard to believe. Is the tech out to lunch?


I have this problem too.

One can't assume, the switching equipment they are using may have their limitations or per company policy certain configurations are not done.

Can't you route the unwanted callers to extension that are never answered ?

Hi Paolo,

When you say "route the unwanted callers to extensions that are never answered" do you mean via the manual intervention of our receptionist?

I'm not sure I can automate this process because again it would require Call Manager to make a routing decision based on inbound ANI which it can't seem to do.

Thanks again

I forgot the CM can't route by calling number.

I guess I'm too used to the router that can.

Why can't you use H.323or SIP on the GW ?

I suppose I could. I was just hoping the telco could save me the trouble. Thanks for the help anyway. Cheers

Unfortunately they are correct, there is no way to do this using MGCP and as you already know CCM can't route calls per calling party number, only per called party. So the only way will be using H.323
