Sentry 3 FAQ

Should I setup the Accept List first?
Yes. SENTRY 3 allows you to preload phone numbers, with or without names, to your Accept List at setup.

Don't like the warning messages?
SENTRY's warning voice is meant for spam callers. The Sentry 3 allows you to record a custom outgoing message or use the factory default greeting. Your friends and family will not hear it after they are on your Accept List. So it is important to preload the "good" numbers to your Accept List at setup.

Can I receive calls from people not on the Accept 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 Accept List and ring the Sentry unit.

Do I need to add “1” to phone numbers when creating the Accept List?
Please check the caller IDs showing on the Sentry's display. If you see CID displaying as “1+10 digit”, then you need to add “1” to each phone number you put in the Accept 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 Accept List?
To create an Accept List without names, enter the phone number using the key pad. Press ACCEPT button to save onto the Accept List.

How to delete a number from the Reject or Accept List?
From the home screen, go to the call log, Acceptor or Reject List pressing the UP/DOWN button, ACCEPT or REJECT. Find the number you want to erase, press the “DEL/EXIT” button twice to delete.

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 until ALLOW/BLOCK NO CID appears on the screen. Then use UP/DOWN buttons to toggle between ALLOW and BLOCK. Press DEL/EXIT when done.

Do Reject List callers hear the warning message?
No. These calls will be hung up automatically.

Do Accept 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 3.1 does display the caller's name and phone number.

Can I use SENTRY for my business?
Yes, but we recommend running the Sentry on basic mode(OFF). This mode allows all calls to come through except the numbers on the Rejecy List. Having the Sentry ON may annoy your callers unless you record a custom breeting with specific message.

How do I get to Home Screen?
Just press DEL/EXIT once.

How to delete a number from caller ID list?
From home screen, press up/down arrow to find the number, then press “DEL/EXIT” twice

Does the sentry 2 or 3 work with internet voip? 
The Sentry 3 does work with VoIP. Each and every house hold are configured differently, please contact our customer support at (714)361-4615 (M-F 9am-1pm Pacific) to check if the unit will work with your communication set up.

Does this work with Ooma?
The Sentry does work with the older Ooma TELO. We do not recommend using it with the new TELO. Please contact our customer support at (714)361-4615 to check if the unit will work with your communication set up.

With the ability to press "0" to be added to the Accept list I assume any scammer who calls can just press "0" to bypass the block?
Yes, there is a possibility that a persistent caller will press “0” to get their call through. When they do, you can add their phone number to the Black List.

How many Accept-listed phone numbers can the unit store?
The Sentry 3 can hold up to 1500 numbers on both the Black and Accept lists.

Does it work with a wireless system?
This question requires some additional information. Please contact our customer support at (714)361-4615 (M-F 9am-1pm Pacific).

Does this also block Skype type calls and international calls?
The Sentry will screen and block all calls with caller id or no caller id.

Does the Sentry 3 run of mains power, or a transformer, or the phone line, or is it battery powered?
The Sentry 3 requires both 3 AAA batteries and the telephone line’s power for it to operate.

Will the caller ID show on my phone and ring, if the device is plugged in serially?
The Sentry 3 allows most phones to connect in series without any caller id issues and without the phones emitting a single ring. Make sure to enable ALLOW 0 RING (press and hold the */RINGER button) for Panasonic and Uniden phones. These phones process the CID data between the first and second ring.

Does this device allow you to input the calls you want to answer?
The Sentry 3 allows users to manually enter phone numbers for both Accept (calls you want) and Black (calls you to reject) lists with the new alpha numeric key pad.

Does sentry 3 work on a DSL line?
Yes, the Sentry 3 does work with a DSL line

Can you edit a Accept list phone number which has name error without deleting it?
The Sentry 3 does not have the edit function. The phone number will have to be deleted and re-entered in order to add a name.

When does the unit record messages from incoming callers?
If the call is not answered by the Sentry’s ninth ring after the unlisted caller presses “0”, a quick voice message can be left after the beep.
