Some people just require a louder ring to be able to hear that there is an incoming call and have no problems at all once they have picked up the phone, and are understandably reluctant to change the entire phone system. This is where the ToneCaller from BT comes in. It provides an additional audible alert that can be set with four different pitch settings. With an adaptor you can use the same socket as your current phone or if required locate the ToneCaller away from your phone on a separate phone socket.
Very simple to set up and saves changing the phone when all you need is a louder ring.
Fully compatible with BT phone lines.Main Features
