In Blacklist, you can create a list of numbers that should be blocked. If a caller is trying to call anyone in your PBX account from a blacklisted number, the call will fail.

Setting up a blacklist

  1. Go to Callflows > Blacklist.
  2. Enter a name for the blacklist.
  3. Enable Block Anonymous, if you want to block any calls coming from an anonymous number.
  4. Add the phone numbers that you want to include in the blacklist.
  5. Save your changes.


  6. Activate the blacklist in Account Settings.
