Troubleshoot a noisy Office Phone line

To identify the cause of noise, static or radio interference on your office phone, follow these steps:

  1. If recent changes were made in the business location, remove any newly installed devices and retest 

  2. If there are multiple handsets within your location, determine if the issue is occurring on one or multiple handsets 

    1. If it is occurring on one handset, try using another jack or a different microfilter. If the problem persists, you should get the handset serviced

    2. If it is occurring on multiple handsets, go to the next step

  3. Unplug all equipment from every phone jack including fax machines, modems, splitters, etc.

  4. Leave everything unplugged for at least 60 seconds

  5. Plug in your most basic telephone, preferably a corded one

  6. Check for any noise, static or radio interference

  7. Add back equipment one piece at a time

  8. Check for noise, static or radio interference after each addition. If the issue returns, remove the last piece of equipment added from the jack. It's probably causing the problem and you may want to have it checked

Note: If you are a TELUS high-speed Internet subscriber, you may require microfilters for each phone plugged into a wall jack.
