Blacklist Module allows you to blacklist certain numbers in your PBX. If a user calls from one of those numbers using the blacklisted DID number as CID, the call will still work with this exact CID. They will be sent to a destination you choose. If you do not choose a destination, they will hear the message "The number you have dialed is not in service. Please check the number and try again."

To blacklist a number:

  1. Log in to your PBX.

  2. Go to ADMIN > Blacklist .

  3. Click + Blacklist Number.
