You can buy our battery back-up unit (BBU) which will keep your phone line connected for up to an hour if there’s a power cut.

You must get agreement from the provider of your service (i.e. health care, burglar alarm) before connecting it to Digital Voice.

You can connect your Telecare alarm to the phone socket on your home hub. You must talk to your Telecare provider and check that they’re happy for you to do this.

You’ll need to talk to your alarm company to check whether their equipment will work alongside Digital Voice.

17.   Your call history (i.e. the last 10 numbers dialled), is stored in your hub. We recommend that you delete this information before getting rid of it. You can do this by pressing the reset button on the back of your hub for 10 seconds. Alternatively, you can return your hub to us and we’ll dispose of it securely.
