Blacklist (Call Blocking)

In order to block anonymous / private callers, you need to add a simple rule to your phone system's Global Blacklist. Instructions below:

1. Log into the PBX Admin portal
2. Go to Call Control > Blacklist
3. Click "Blacklist a Number"
4. Set Telephone # to 0000000000 (exactly 10 zeros)
5. Set Notes to "Block anonymous calls"
6. Submit

From now on, anyone who attempts to call in anonymously will be treated with a busy signal.
