Two former telemarketers have come up with a device that could put their former colleagues out of a job. Called TrueCall, it’s a buffer between the landline and calls, and can be taught to distinguish between calls that are welcome and those that aren’t.
If the number calling is on a welcome list, the call is put through, the BBC reports. Those on a zap list it receives an automated message and your phone never rings. With unrecognized numbers or ones with no number given, TrueCall asks their name, puts them on hold and rings through to your phone.
