Answered Question

We have CCM V4.2 and Cisco voice gateways-Cat6k version 12.4

Is it possible to block incoming calls by caller ID on voice gateways or CCMs?

I have this problem too.

As an addendum to this post (good post Rob), it should be noted that this is also valid with SIP. I think some of these were written before SIP really hit it's prime so it was not included.
