Troubleshooting No Dial Tone & Clarity Issues


No dial tone or phone says “Line in Use” but no one is on the phone

Check that your phones are hung up properly and/or turned off.

Checking the phones can sometimes clear any trouble that you may be having and it also may reduce the chance of a service charge if your telephone equipment is found to be faulty or is the cause of the problem. The best way to check your telephone equipment:

  1. Unplug all equipment plugged into the phone jacks, i.e., telephones, fax machines, answering machines, etc.
  2. We recommend you use a corded (analog) phone to check the jacks for dial tone. If you do not have a corded phone, use what you have but check multiple jacks in your home.
Noise on the line

Noise on your telephone can be caused by many different factors. It may sound like a hum/buzz or static/crackle. If this is occurring on your telephone line, try the following:

  1. Check connections on the telephones and the cords connecting the telephones to the phone jacks. A loose connection can cause this issue.

Checking your telephones and connections may clear the issue and reduce the chance of a service charge if the trouble is found to be a faulty telephone.
