1. If no dial tone is present on your phone, check to make sure that all receivers are on the hook and the telephone line is plugged into the jack.
2. If the problem is on one phone only, use a different phone. If you still do not have a dial tone, try a different phone jack to determine whether the issue is with the phone or the phone jack. If the issue is with the phone jack or is happening on all of your phones, contact Verizon Repair for assistance.
3. If your problem is happening on all of your calls, go to each connected device (such as your phone, modem, and fax) and begin to disconnect them one at a time.
4. After you disconnect a device, leave it disconnected. Wait 30 seconds, then go to the next device and check if it has a dial tone. If there is a dial tone, then the last device that was unplugged is the faulty device and should be replaced.
5. Reconnect all other devices except the faulty device and check each for proper operation. If the faulty device now works, mark it and if the problem happens again you can check that device first.
If only one of your phones is causing the problem:
1. Check to ensure that your phone is turned to touch tone (tt). This switch is usually located on the side or bottom of the telephone set.
2. Press each button on the phone's number keypad to ensure that they are not sticking or making a dull sound instead of a clean tone.
3. If you hearing a fast busy signal or a delayed dial tone there may be a surge in the phone line usage in your area.
4. Try making your call later when phone lines are less busy.
Troubleshooting steps
If only one of your phones is causing the problem, check your phone equipment:
1. Unplug the phone from its wall jack.
2. Plug a working phone into the jack.
3. Check to see if the problem persists.
If the problem continues
Other reasons that might prevent you from being able to call out include:
If you are hearing static on your phone, check that the problem is not originating from your equipment.
If you are sure you are calling the correct number, check your phone equipment.
1. Unplug the phone from its wall jack.
2. Plug a working phone into the jack.
3. Check to see if the problem persists.
If the problem no longer exists then there is an equipment problem with the first phone you were using.
Static on a cordless phone
If you are using a cordless phone, unplug the phone from the wall outlet and the jack.
If the problem is resolved by removing the phone, refer to the cordless phone owner's manual or replace the equipment.
If the problem continues
Isolation tests on phone systems or multi-line equipment should be performed only by authorized or certified personnel to avoid damage to the equipment.
