The Digitone Call Blocker Plus was designed for those who want an automatic way using Caller ID service to block unwanted calls yet allow all others to ring their phones. It comes from the factory preset to allow all callers with a valid phone number to ring through and then screens your calls based on a Blocked Caller List you prepare.  The Digitone Call Blocker Plus has a 140 number memory for blocking unwanted calls including individuals or area codes and a 50 number VIP Caller List for preferred callers in After Hours mode.   Each memory slot can be used for whole area codes (10 Million numbers), exchanges (10,000 numbers) or individual numbers.  30 Day Money Back Guaranteed*.

How the DCB Plus works

The Digitone Call Blocker Plus comes from the factory preset to allow all callers with a valid phone number displayed to ring through just like normal. Block unwanted calls are Unknown, Unavailable, Out of Area, Anonymous, Private or any name without a phone number and will be hung up on.  Also, the phones throughout your home or office will continue to ring on Invited calls until the ninth ring, when the call blocker will answer the call and hang up to prevent a caller from tying up the line.  Alternatively, if you miss your Invited caller, your combo phone/answer machine or your phone company's voice mail service will take a message for you.  

The Digitone Call Blocker Plus has added and updated features to the previous version DCB10:

1)  More memory for blocking - 140 individual numbers or whole area codes
2)  Block up to 20 Names besides Numbers
3)  Five Operating Modes including: Standard, Business, Select , After Hours and Standby
4)  PBX extension numbers 1-6 digits pass through for business systems
5)  Instant Hang-up of an incoming call you want blocked and added to the Blocked List using the Block Button
6)  Increased Invited and VIP number lists to 50 numbers each, area codes & wildcard strings 

With First Ring Suppression (tm) none of your phones connected to the TEL port of the DCB Plus will ring.  Blocked unwanted calls will be answered immediately and then hung-up on. They only hear the first ring tone on their side, silence and then a hang-up.  Blocked numbers can be pre-programmed in using your telephone or added as you go by simply using the front panel controls.  Simply scroll up or down using the View Call History buttons and then press the Block button twice to block that caller.

In Business Mode, you can still allow any caller, including Out of Area, Private, Unknown, etc. to ring through to your phones/answer machine as needed for business while blocking unwanted calls with displayed numbers.  

If you do not want to invite everyone, you can invite just specific callers and block unwanted calls using the Program button and the instructions in the manual for installing Blocked and Invited or VIP numbers.

Telemarketers 800, 855, 866, 877, 888
