CUCM Call Routing Based on Calling Number

Good day,

Today's post will focus on the subject, which have been increasingly interested in by my students and blog readers. We will talk about how to route the call in CUCM depending on the calling number. This problem arises, typically, in situations where you want to block incoming calls from certain numbers, or, vise versa, to allow incoming calls only from certain numbers and all other call must be denied. Consider, for example, that the second task, ie, let's deny all incoming calls, except calls from certain numbers.
