Blocking Inbound Numbers

What is the best pay to block inbound numbers on CCM 4.1(3)SR1. For example, we have this one particuler number that is probably a computer generated number that keeps calling. When we pickup no one is there.

Where can this be filtered? Thanks!

Re: Blocking Inbound Numbers

If your PSTN provider can block it there are some advantages. First you don't have to do it, second even though you can, it does tie up a channel coming into your gateway for the time it takes to reach CallManager and reject it. If it is a computer generated call, it could be making several at a time and could result in a sort of DOS on the gateway. Other than that, you could route it to non-existant phone or I think use a route filter. I would also setup reporting on it to verify the block is working.

If you have H.323 GW you can make translation rules:

Re: Blocking Inbound Numbers

It is actually a MGCP gateway not a H323 gateway.

Re: Blocking Inbound Numbers

Then you won't be able to do this per incoming number basis.
