Digitone ProSeries 3 Call Blocker for Landline Phones

The Digitone ProSeries 3 Call Blocker effectively blocks unwanted SPAM calls automatically, ensuring that only preferred calls ring through with Caller ID displayed. Phones connected to the TEL port will not ring on blocked calls. Users can create a whitelist of allowed callers and employ dual block buttons to stop specific names or numbers easily. The device can also remotely block calls using the telephone handset. This patented call blocker handles various types of unwanted calls, such as unidentified numbers, private numbers, and services like ROBO calls, allowing users to feel confident as it has already blocked millions of known unwanted numbers. No changes to existing phones or services are needed, as it is compatible with any analog corded or cordless phone or fax system. The device features a large backlit display for easy viewing. It works seamlessly with all USA phone companies, including AT&T, Cox, Spectrum, and various VoIP services, as well as across multiple countries with North American standardized phone lines. Users can also allow any blocked caller to ring through by pressing the Green Invite Button and can double-tap this button to add VIP callers from Call History to their whitelist.
