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.
