If you are hearing static or an echo while talking on the phone, check to ensure there isn't a problem with your telephone equipment. An echo causes callers to hear the sound of their own voice. Try the following steps to clear the problem.
Corded Phone Unplug the phone from the wall jack. Plug a working phone into the jack. Check to see if you still hear static. Cordless Phone Unplug the phone from the wall outlet and the jack. Check to see if you still hear static. If the problem goes away, repair or replace the phone you just unplugged.
In both cases, if the static persists you may do the following: Outside Testing Take at least one of your phones that doesn't have a built-in speaker or lights to the Network Interface Box. (This is where our outside line and your inside telephone wiring connect; also known as a Standard Network Interface (SNI), a Network Interface Device (NID), or a NetWork Interface (NWI).)
The Network Interface Box is usually located on the outside wall of your home near the electric meter. Although your Network Interface Box may look different you should still be able to follow these step-by-step instructions. Bring a screwdriver, or a similar tool like a flat-edged butter knife, a telephone, a flashlight and printed copy of these instructions with you. Use the screwdriver to open the customer access side of the network interface box. Disconnect the modular plug from the test jack and follow these steps: Plug your phone into the test jack. Make a phone call and listen for the problem. If the same problem occurs, use a second phone and repeat above steps.
Note: Please use discretion when testing in the Network Interface Box. Although the lines are grounded, do not attempt to test the lines during a storm or if you are standing in a puddle.
If you have the same trouble as you were having inside your home with one of the phones you just tested, the cord or phone you were using is probably defective. If you have the same trouble with two different phones, the trouble is probably outside your home. If you are unable to clear the trouble, call our repair service at 611 from your local exchange or 1.888.PTC.COOP (1.888.782.2667) for assistance.
We will make repairs to our outside line and switching equipment at no charge to you. If there is no problem with any of the phones you just tested, the trouble is inside your home. It could be with a telephone you were not using outside or with the inside wiring.
