If you would like to proceed, tap Restart device. Restarting your modem should take about five minutes.
The My Account app will send a restart signal to your modem.
Once the restart signal has been sent, please wait about five minutes for the modem to light up again. Then, check if you can hear a dial tone on your Xfinity Voice line. If this fixed your issue, tap Yes.
To exit Troubleshooting, tap Done. Then - you're all set!
Offline Troubleshooting
If your Xfinity Voice modem is detected to be offline, please try powercycling the device to bring it back online by following these steps:
Unplug your modem from the power cord and coax cable. If there is a battery present, please remove it.
Wait at least 15 seconds.
Plug your device back in to power it on and reconnect the coax cables. If you removed the battery, place it back in. Then, tap OK, I've completed these steps.
Home Wiring Troubleshooting
If you already powercycled and/or restarted your Xfinity Voice modem, and the original issue still persists, please note that home wiring can affect your ability to make calls. Make sure all phones are on the hook and that any cordless phone batteries are charged.
If you are using home wiring, tap Yes.
Try plugging your phone line directly into your Xfinity Voice modem. Find the port behind the device and plug your phone line directly into Tel 1, as pictured below. If this fixed your issue, tap Yes.
Then, check if you can hear a dial tone on your Xfinity Voice line, which would indicate home wiring issues. If so, tap Yes again.

Still Having Issues?
Please follow the suggestions below to try and restore service:
Try to plug a working corded phone into different jacks to find out if the issue is isolated to one phone or jack.
Plug the phone directly into your Xfinity Voice modem to determine if the issue may be related to the wiring inside your home.
If you have two phone numbers with Xfinity Voice service, and only one is working, please contact us.
Check the lights on your digital voice modem (see below). Depending on the light sequence displaying, you may need to reset your modem.
What the Lights on Your Xfinity Voice Modem Mean
An Xfinity Voice modem combines your cable modem and analog telephone adapter. The lights on the modem indicate different functions; this explains what they mean. Note: Here is a typical modem diagram:
Below are descriptions of these lights.
Telephone 1 or Telephone 2
A solid light indicates the phone(s) are on the hook.
A flashing light indicates a phone is off the hook.
If the light is off, you'll need to reset the Xfinity Voice modem. See reset your modem for Xfinity Internet or Xfinity Voice for instructions.
If the light is flashing very slowly, please chat with us.
Battery 1 or Battery 2
If your Xfinity Voice modem is equipped with two battery slots, only one battery is needed in order to receive up to 24 hours of backup power.
One of the battery lights should be solid if the battery is good and connected properly. Your connection should not be affected by the status of the battery lights as long as you have power to the modem*.
If the battery light is off and you have a backup battery inserted into the modem or connected to your modem (depends on modem model), make sure the battery is securely connected to the modem. If you do not have a backup battery installed, this light will remain off.
If the light is flashing, your battery is depleted and may not provide backup power in the event of an outage.
A backup battery can be installed in your Xfinity Voice modem to provide additional hours of service during a power outage. If your battery is missing or depleted and you would like to purchase a new one, find out more information on purchasing a battery.
Xfinity Voice Service Interruption
*If Xfinity Voice service is interrupted as a result of downed cables connecting to your home or cuts to other portions of our network (as can happen in cases of severe storms), the service will not function until those facilities are restored. Depending on the specific facilities impacted, traditional phone providers may be affected.
