記事ID:

I can't hear a dial tone in the headset.  What should I do?
  • Press the call control button to see if you hear a beep in the headset. If you do not hear a beep, try charging your headset. If you do hear a beep, the headset may no longer be linked to the base. Try resubscribing the headset to the base.

  • If the problem persists, ensure the phone is off the hook. If using a handset lifter, make sure the lifter is lifting the handset completely off the hook.
  • If the problem persists, pick up your handset and verify that you can hear a dial tone. If you do hear a dial tone on your handset, adjust the configuration switch on the base. If you do not hear a dial tone on your handset, then contact your company's telecommunications department.
