Landline issue

Hi @TyNone! Thank you for reaching out to us! We understand that you're facing issues making incoming or outgoing calls from your landline phone. We hear you, and are happy to assist you.

Please check for outsides issues:

If your issue occurs on more than one phone, you can perform outside testing to find out if the issue is in your home or with the AT&T network.

1. Locate the Telephone Network Interface. It’s usually located on the back or side of the house.
2. Use a screwdriver to open the box. Look for a phone jack labeled customer access jack.
3. Unplug the short telephone cord and plug in your corded phone.
4. See if the problem still exists. If you:
   • Don’t have a clear dial tone: The problem is with the AT&T network. You’ll have to submit a repair ticket online at att.com/repair or call us. Be sure to tell the repair specialist about the troubleshooting steps you have take
   • Do have a clear dial tone: The problem is inside your home, and you should check for inside issues.
5. Unplug the corded phone and replace the short telephone cord. Make sure you close and tighten the Telephone Network Interface cover.

Check for inside issues:

If the problem doesn’t occur when you’re connected to the Telephone Network Interface, the trouble is inside your home. It could be caused by a connected DSL filter or from interference from electronic devices in your home.

Check devices connected to DSL filters

If the problem occurs with one phone, and it’s connected to a DSL filter:

• Check your DSL filters: Turn off or unplug your modem. If the issue went away, then a DSL filter is likely the problem.
• Identify the failed DSL filter: Unplug one filter at a time from the telephone jack (wall). Leave the DSL filter you just unplugged attached to the device. Use another phone and DSL filter on a different jack to see if the problem still exists.
• Test your devices: Plug in all of your DSL filters and devices, one at a time. Perform a test after each device is added. If you still have the problem, it is likely the phone, fax, or other device is defective. Remove or replace that device.
