A corded phone is recommended for this test. If you are using a cordless phone please ensure it is connected to an electrical outlet.
If the problem does not occur
- Unplug connections and power supplies for all telephones, computers, faxes, modems, satellite television or cable boxes, alarm systems, adapters and filters.
- Once everything has been unplugged, test your telephone line(s) with a single phone by plugging the phone directly into a telephone jack (wall).
Begin adding the equipment you just unplugged one piece at a time. Check for the problem after each addition. When you find the problem, it was likely caused by the most recently added piece of equipment. Repeat until all of the equipment has been successfully added (you may have more than one piece of equipment causing interference).If the problem occurs with a single phone
Test using another telephone. If the problem does not occur with the second phone, your issue is likely with the first phone.If the problem occurs with two phones
Test both phones, one at a time, on a different telephone jack. If the problem does not occur with the second jack, your issue is likely with the first jack. For each cordless phone, ensure the batteries are fully charged and the cord between the telephone base and jack are plugged in and secure. If you are experiencing interference, try changing the channel. Additional information
