Symptom Solution
Forgotten Voicemail Password / Passcode Please call technical support at 1.800.239.4430. An agent will be happy to reset the voicemail passcode for you.
Calls Go Straight to Voicemail Log in to your Frontier account and see if any of the following features are enabled:
  • Call Forwarding to the voicemail access number
  • Do Not Disturb is set to send callers to voicemail
If you still have problems, please call 1.800.239.4430.
Deactivate Voicemail If you have your own home answering machine, you can turn off voicemail so they won't interfere with each other. Please contact technical support at 1.800.239.4430.

Phone Doesn't Ring Check your phone to make sure that the ringer is set to a level that you will hear easily. Make sure Call Forwarding and Do Not Disturb are not enabled by going to the “Call Manager” section of um.frontier.com. If you still have problems, please call technical support at 1.800.239.4430.
No Dial Tone
  • Make sure your telephone is plugged into the wall jack.
  • If your phone needs electricity (e.g., cordless phone), make sure it is plugged into a working power outlet.
  • If your phone runs on battery power, make sure the battery is charged.
If you still have problems, please call technical support at 1.800.239.4430.
Fast Busy Signal A fast busy signal may mean you have a balance due. Please call technical support at 1.800.921.8101 to see if there is a problem with your account.

Power Outage Your Frontier Digital Voice service needs electricity to function. In case of a power outage, the Battery Backup Unit (BBU) will power your basic Frontier Digital Voice services—including 911 dialing—for a minimum of 8 hours. Be sure you have a fully-charged battery inserted in the Unit. Note:
  • 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 Frontier 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 purchasing and/or replacing the battery in the BBU.
Out-of-Service Back-up Phone Number If there is an area-wide outage or you've lost power and do not have battery back-up, Frontier Digital Voice lets you choose a number where your calls can be forwarded. Once your phone service has been restored, the forwarding will stop automatically.



Unavailable Call forwarding can be set up on um.frontier.com under Setting. Once you are in the Setting page, go to the Calls tab.



Note: If you have enabled Selective Call Forwarding or Call Forwarding, the numbers you have set for Call Forwarding will override the Unavailable Call Forwarding 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 Unavailable Call Forwarding.
