Troubleshooting Cox Voice
Having issues? We’ll help you figure them out - because we all know there’s no time for downtime.
No dial tone?
Let's make sure it's not a simple setup issue.
Still no dial tone?
Check the lights on your modem to see possible issues, then find their corresponding solutions below.
All lights are flashing
If all the lights are flashing on the Internet and telephone modem, it may be picking up some interference from your house phone wiring.
TEL lights are flashing
If the TEL light(s) are only flashing on the front of the modem, then the modem thinks the phone is in use.
Locate the small "Reset" button on the back of the Internet and telephone modem. It is a small hole that a pen tip or paperclip can fit into.
Press the ‘Reset’ button and release it immediately. All of the lights on the front of the modem should turn off and slowly begin to turn back on.
When the 'TEL 1' and 'TEL 2' lights stop blinking, the Internet and telephone modem is fully reset.
