Troubleshooting Home Phone for Call Dropouts

  1. Ensure your handset has power. Wireless handsets in particular may require charging or new batteries.
  2. If you suspect your handset is faulty due to age and/or wear and tear, we recommend obtaining another handset for troubleshooting.
  3. Unplug all devices from every phone socket in your premises, including your modem, telephones, fax machines, pay TV boxes and EFTPOS terminals.
  4. Plug your handset directly into the phone socket (without a line filter).
  5. Make a test call and see if the call drops out. Repeat this step for all phone sockets in your premises.
  6. If your calls drop when your phone is plugged into one socket but not another, there may be a problem with your home’s internal wiring. If you suspect this is the case, please contact an ACMA-licensed electrician to investigate.
  7. If the call dropouts stop when the handset is the only thing plugged in to your wall socket(s), then another piece of hardware is most likely interfering with your phone signal. The most common culprit is a faulty line filter.
  8. All phones and fax machines in your premises must be plugged into a phone socket with a line filter.
  9. Plug your handset into the phone socket with a line filter and attempt to make a call. If the call dropouts start again, that line filter is most likely faulty and should be replaced.
  10. Plug your other devices back in one at a time (including their line filters, if applicable) and attempt to make a call after each new device is plugged in.
  11. If the call dropouts start again, then the device you’ve just plugged in may have a faulty line filter that should be replaced.
  12. If a fault needs to be lodged for your service, we'll need the date, time, and number dialed for at least 3 calls that dropped out. Please make notes for easy reference, e.g:
    27/4/2020 - 7:30PM - 9400 1234
    28/4/2020 - 8:30AM - 9400 5678
    28/4/2020 - 10:00AM - 9300 1234
  13. Call us on 13 22 58 for further assistance.
