Some signs that telephone wiring needs to be repaired include static, no dial tone and the inability to make calls, states Baldwin Telecom. Telephone wiring problems can be inside or outside of the home and may require professional repair.
Inside wiring problems can carry multiple symptoms, including a noticeably broken phone jack or a phone that is able to work through one jack but not another, according to Baldwin Telecom. Outside wiring problems can cause a lack of a dial tone, the inability to call out, static on the phone or dropped calls from all phones on all phone jacks. If customers are experiencing any of these symptoms, they should contact a professional technician for a diagnosis and repair.
