SENTRY vs. Others

What is BASIC MODE

This is the conventional way of call blocking. In this Mode, SENTRY blocks calls that are on Black List. Just put the unwanted caller number to the Black List, it will be blocked. SENTRY’s Black List capacity is 9999.

What is ADVANCED MODE

In this mode, SENTRY's "Stop and Check” system screens all incoming calls . It is acting like a true sentry that stands guard your telephone 24/7. It recognizes your ‘Good’ callers (on White List), and let them pass through. It recognizes those on the Black List and hangs up on them directly. For a caller not on either list, SENTRY will stop it and perform the checking (the Voice). All ‘BAD’ callers will be turned away by the Voice, and ‘Good’ callers can press 0 to ring SENTRY box, and you can answer the call. A caller not on White List yet will not be able to access the voicemail. And this may be a problem in the beginning and that’s why we advise you to use BASIC MODE first.

FAQ

Should I setup the White List first?

No. You cannot setup White List upfront. Sentry 2 allows you to preload White List upfront.

For people not on White List yet, can I receive their calls?

Yes. They will hear the SENTRY's voice, and they can press "0" to come in.

Do White List callers hear the warning message?

No. Those calls will ring on your phone as usual.

Do Black List callers hear the warning message?

No. These calls will be hung up automatically

Does SENTRY's caller ID show caller names?

SENTRY can only show caller numbers. However, your home phone will show caller ID as usual.

How SENTRY works

  • SENTRY is a ‘check point’ to screen all incoming calls.
  • SENTRY's 'check point' has two lines of defense. First is a voice warning message, that tells solicitors to leave, and tell legitimate callers to come in by pressing 0.
  • At this point, 100% robo calls will be stopped, 99% of solicitor callers will leave.
  • The second line of defense is SENTRY's Black List function. You can put any number on SENTRY's caller id list to the Black List.
  • In reality, the first line of defense is so effective, you rarely need to add a number to the Black List.
  • For the legitimate callers, SENTRY lets you create a White List. Callers on White List will be allowed in without hearing the warning message.
  • If the caller is on White List, SENTRY allows the caller to come in without asking.
  • If the caller is not on White List, SENTRY will ask all telemarketers/solicitors to hang up, and will tell ‘legitimate’ callers to press 0 to come in.
  • Put a caller to White List is easy. Just find the number on caller id list and press ACCEPT.
  • The first line of defense is so effective that you rarely have to use Black List to block off persistent offenders, if any. No robo calls can penetrate SENTRY.

Tips to best use SENTRY

  • Create White List. Your loved ones will pass through SENTRY without ‘checks’.
  • When used as a junk fax blocker, it blocks all faxes that are not on White List. Set SENTRY to ‘OFF’ (press VOICE button) when you anticipate a fax that is not on White List. Put that number to the White List after receiving the fax.
