Troubleshooting Home Phone - Line Noise
topics: phone

This article will explain what to do if you're hearing line noise on your landline home phone.


Symptoms

  • You hear any of the following while making a call: buzzing, crackling, static, screeching, or popping.
  • You may hear line noise when you lift the phone handset, even if you're not on a call.
  • While on a call, voices may be distorted or intermittently drop in volume.


Things to check

Check that your phone issue isn't being caused by the following before proceeding with the troubleshooting:


Potential cause
Try this:
Phone line maintenance in your area Check this by entering your post code or suburb here.
Poor signal or issue with the other caller's phone service If you only hear line noise when you call a specific number, it may be their phone service that has an issue, not yours. You can check this by making some test calls to different phone numbers.
Central splitter required If you have more than three telephony devices or a Back to Base Alarm system, you may need to contact an Austel Approved installer to install a central splitter.


Troubleshooting

  1. Unplug all devices from every phone socket, including your modem, telephones, fax machines, pay TV boxes and EFTPOS terminals.
  2. Plug a standard phone handset (without a filter) into the phone socket, and then make a call, listening for line noise. If you were able to make a call without line noise, skip to step 6.
  3. If you have more than one phone socket in your home, plug your phone handset (without a filter) into each of those sockets and make a call, listening for line noise. If you hear line noise when your phone is plugged into one socket but not another, there may be a problem with your home's internal wiring.
  4. Using a different phone handset, repeat steps 2 and 3. If you hear line noise on the original phone handset but not a different handset, then the original handset may be faulty.
  5. If you hear line noise on both handsets, please call our Support Team on (03) 8789 4988 for further assistance.
  6. If you don't hear line noise any more, plug your phone handset into the phone socket with a filter and make another call, listening for line noise. If you hear line noise again, that filter may be faulty.
  7. Plug your other devices back in (one at a time) and attempt to make a call without hearing line noise after each new device is plugged in. Always start with any devices that require a filter.
  8. If you suddenly start hearing line noise again, then the device you've just plugged in may be faulty or interfering with your phone service, or it may be plugged in with a faulty filter.
  9. We recommend replacing a filter or device if it is faulty, or adding a filter to a telephony device if it didn't already have one.

Why do I need to test a different phone handset?


More information

Phone problems can be caused by several things, but a common cause is faulty hardware.


If Gtelecom Australia lodges a fault for a phone line when there is no fault, then you may be charged an incorrect call-out fee by our wholesaler's fault technician. To reduce the risk of this, we need to rule out as many other possible causes for your phone problem as we can.


If you hear line noise on the original phone handset but not a different handset, then the original handset may be faulty.
