Power outages
Your Fiber Digital Voice service requires electrical power to function. In case of a power outage, the battery backup unit will power your basic Fiber Digital Voice services — including 911 dialing — for a minimum of 8 hours. Be sure you have a fully-charged battery inserted in the nit.
Note:
Out-of-service back-up phone number
Fiber 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 Frontier Digital Voice Web Portal:
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.
