Your Home Phone Unlimited service uses electrical power to function. If you lose power a battery backup unit (BBU) will provide power to your phone and keep it connected to make phone calls, including emergency 911 calls.

To be sure you are protected with this function, we've partnered with International Resources to bring you the equipment you need for your voice over IP telephone service. Shop the link below to order battery backup units, battery pack extenders and stay connected even if the power goes out.

Installing a battery backup unit is optional for your Home Phone Unlimited service. Please note that battery backup units only provide access to your telephone service during a power outage. It will not work for your Ziply Fiber internet and/or video services.
