            Power outages and out-of-service back-up phone number

            Power outages

            Your Unlimited Digital Voice service requires electrical power to function. In case of a power outage, the battery backup unit will power your basic Unlimited Digital Voice services — including 911 dialing — for a minimum of 8 hours. Be sure you have a fully-charged battery inserted in the unit.


            • If the battery is drained or there is no battery present, the Service will not function for any purpose.
            • If your home security system is currently using a jack in your house, those same jacks can be used for Unlimited Digital Voice without impacting security services. In the event of a power outage, the power limitations apply to your alarm system.
            • The BBU will not power your internet services, television services, or computer. You are responsible for buying and/or replacing the battery in the BBU.

            Out-of-service back-up phone number

            Unlimited Digital Voice lets you choose a back-up number where your calls can be forwarded. This is important if you have a power outage and don't have battery back-up. Once your phone service has been restored, the forwarding is stopped automatically.

            Back-up numbers can be set up using your Unlimited Digital Voice Web Portal:

            1. Sign in to um.frontier.com
            2. Click Setting
            3. Click the Calls tab
            4. Set up unavailable call forwarding

            Note: If you have enabled either Selective Call Forwarding or Call Forwarding, the phone numbers you have set will override the Back-Up Number. If you have Voicemail activated to take your calls or have Simultaneous Ring or Locate Me enabled, your call will go to your specified Back-Up Number.

            Battery backup for Unlimited Digital Voice

            Unlimited Digital Voice service needs your home’s electricity to work. If you lose power, a battery backup unit can power your phone so you can make phone calls, including emergency 911 calls.
