How to block spoofed calls on Expressway E

carl_townshend · ‎12-23-2021

Hi All

We keep getting spoofed calls coming through on our expressway E and they are calling telephones on our CUCM. They appear to be using our domain name in the source number for example 100@mydomain.com.

I have added search rules at the top to block things coming from our domain e.g (.*)(@mydomain.com) and 100@mydomain.com then setting it to reject.

Is this correct, or is there something else I need to do?

cheers

This pops its head up repeatedly over the years - have a look back through the forums with the search tool and you'll find many occurrences and threads to help solve the issue.

There's some good options in some of the older threads like this one: Unwanted Automatic Call hitting on my Expressway E
