Busy Signal Dial Tone

Busy Signal Dial Tone

Is the phone system out?  Our landline is not working - the dial tone sounds like a busy signal.  What is the problem / how is it fixed?

Re: Busy Signal Dial Tone

You should check to make sure that all of your other phones are on the hook.  If this does not fix the problem, you should try rebooting your modem.  You can also try plugging a working phone directly into the modem to see if there is a problem with your house's telephone wiring.  If these steps do not work, you should give Comcast a call.


If you want to reboot your modem, you can use a ball point pen or paperclip to press and release the reset button on the back of the phone modem.
