FAQ

Should I setup the White List first?

Yes. SENTRY 3 allows you to preload numbers to your White List at setup.

Don't like the warning messages?

SENTRY's warning voice is meant for spam callers. Your friends and family will not hear it after they are on your White List. So it is important to preload the "good" numbers to your White List at setup.

Can I receive calls from people not on the White List?

Yes. They will hear the SENTRY's voice and can press "0" to come in. By pressing "0" their number will be automatically saved to the White List.

Do I need to add “1” to phone numbers when creating the White List?

Please check the caller IDs showing on your home phone. If you see CID displaying as “1+10 digit” on your phone, then you need to add “1” to each phone number you put in the White List.

Do I need to reject a Spam call by pressing the REJECT button?

No. You don't need to reject any calls. SENTRY does it for you. Spam calls cannot get past SENTRY's defense.

How do I add a friend's number to White List?

How to delete a number from the Black or White List.

Can I block all calls that show no CID(Caller ID)?

Yes, on the home screen press and hold the “REJECT” button for 2 seconds, you will see BLOCK NO CID on the screen. To cancel, repeat the same procedure.

Do Black List callers hear the warning message?

No. These calls will be hung up automatically.

Do White List callers hear the warning message?

No. SENTRY will recognize their number and let them in directly.

Does the caller ID screen show caller names?

SENTRY displays caller numbers only. However, You can see CID with names on your home phone as before, if you connect SENTRY using option 2. Option 1 displays CIDs on most AT&T or VTech phones only.

Yes, but Black List (Basic) mode only. White List mode is not recommended for business since it stops and checks all unlisted callers. This may be annoying to your customers.

Just press DELETE/HOME once.

How to delete a number from caller ID list.

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.
