No, the Tonecaller is a universal device as it does not require connection to a telephone. It connects directly to your telephone line.
The Tonecaller must be plugged directly into your telephone line, however your telephone will also have to remain connected. Unless you already own it, or have multiple devices connected to your telephone line, you will require a standard BT 2 way adaptor – please click here to buy.
Please ensure there is no more than 4 devices connected to your telephone line. A standard telephone line can power a maximum of 4 devices (REN 4). If more devices are connected some may function incorrectly or stop working altogether.
