The Digitone Call Blocker Pro is designed for those who want an automatic way using Caller ID service (or no CID service) to block unwanted calls yet allow all others to ring their phones. It is preset to allow all callers with a valid phone number to ring through and then screen calls based on a Blocked Caller List the user prepares. The Digitone Call Blocker Pro has a 160 number memory for blocking unwanted calls including individuals or whole area codes and a 30 number VIP Caller List for preferred callers like family, friends and business associates. The Pro model can work with or without caller ID to capture blocked callers or for those Invited callers who enter an access code to ring through.
It can be used worldwide by all countries using FSK/DTMF Caller ID including all of the USA, Canada, Mexico, South Africa, Argentina, Singapore, and Germany, to name a few. Digitone has been the standard for call blocking for many years, which is why the FTC should consider this consumer premise equipment as an absolute fixture for every landline and/or cell phone that is rung up at the same time.
