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
- From the Callflows app, go to Blacklist.
- Enter a name for the blacklist.
- Enable Block Anonymous, if you want to block any calls coming from an anonymous number.
- Add the phone numbers that you want to include in the blacklist.
Save your changes.
NOTE: You can activate the blacklist in Account Settings.
