Troubleshoot call audio disturbances on your IBLc phone

If you are facing a disturbance during a call on your IBLc corded phone, like a static or humming noise, try these troubleshooting techniques:

Start with this technique:

1. Unplug each of your phones from its jack and try connecting a single phone to isolate the problem to a specific phone or jack.
   1. If you don't hear static or humming noises, try step 1 with another phone on a different jack.
   2. If you still hear static or a hum, also try step 1 with another phone on a different jack.
      
      

If you still hear static or humming noises after trying all your phones on all the jacks:

1. Check each of your phones for stuck buttons, damaged keypads, or other damage. 
2. Check each of your jacks for physical damage or loose wiring. 
3. If you have a key system or PBX, please contact your interconnect company. 
   
   

If none of the steps above removes the static or hum, call our Business Support Centre at 1 (866) 727-2141 and ask for Technical Support (option 3).
