short description is not available

Major upgrades to SENTRY 1 & 2. The only thing you need to do is to create a White List, and let SENTRY3 do the rest. Now you can easily and quickly create White List using the new number pad. You can also create your own custom OGM in any fashion or language. All other call blockers rely solely on Black List to block, they can't block unknown calls that are not on Black List. SENTRY’s unique Active Screening can block all junk calls regardless of known or unknown. All you need to do is to set up a White List that contains the good contacts who call your home phone. White List callers will bypass SENTRY to ring your phone. Unrecognized calls will be screened by SENTRY which broadcasts a voice message to the caller that turns away the spammers and ushers in the good callers. Effectively eliminates phone frauds targeting seniors.
