Two lists with PREMIER TELEPHONE ACCESSORIES Version 3, Lists are Whitelist & Blacklist
Each new call to your phone (connect with PREMIER TELEPHONE ACCESSORIES) will get a warning from Sentry. And visitor needs to press “0”, and then they will be added to white once-over unendingly unless you remove it. Or you can add numbers and letters to white once-over physically.
Keypad: adding numbers and letters to white list is much simpler.
Blacklist: adding undesirable numbers to blacklist, then PREMIER TELEPHONE ACCESSORIES will block them.
