The Jabra wireless headsets are designed to work with various telephones. Most phones will work fine with the default setting on the wireless headset. If your lifter is acting erratic you will need to change the "default mode" for the Remote Call control within the settings of the wireless headset to "GN1000/RHL mode". The default mode performs "auto sensing" for incoming calls that does not perform well on certain phones such as NEC and Toshiba phones. In most cases the fix below will clear up the problem. If this does not clear up the problem you may need to replace the lifter. You can purchase a new GN1000 lifter here.
To change this setting on a Jabra 920 visit page 25 of the user manual for instructions on how to change the Remote Call Control mode. Otherwise you can follow the steps below.
1 Start setup mode

3 End setup mode
When finished, simultaneously press and hold both headset volume buttons until the voice prompt says “Goodbye” and then release the buttons. the base will restart and update the settings, indicated by the white battery icon on the base.
If you have several headsets that are experience this issue you can copy the headset settings to multiple Jabra 920 wireless units by doing the steps below.
COPY SETTINGS TO MULTIPLE JABRA PRO 920 BASES
Jabra PRO 920 settings can be manually copied onto other Jabra PRO 920 bases.
1. Dock the headset in the base.
2. Press and hold the headset mute button until the headset LED flashes, and then release. When the settings have successfully copied, the headset LED will turn solid white.
3. Undock the headset and dock in the new base to copy the settings to the new base. The headset LED will flash 5 times to indicate the settings are being copied, and then will turn solid white when successfully copied to the new base.
