My Phone Has No Dial Tone or the Telephone is Not Working

What to do if your telephone has not dial tone or is not working

User Experience

There is no dial tone or the telephone is not working.

How to Solve this Problem

Check to make sure the telephone is plugged into a jack. If it is not, generally it will need to be plugged into the first outlet (left side) in the jack. If you have four outlets in your jack, the top left port is the one normally used for telephone connections. If the phone is plugged into the correct outlet and still has no dial tone, see the Telephone Support page.
