Note
If headsets are deployed in high static environments where users frequently
disconnect and re-connect the headset to the phone, it is possible that the phone
can be damaged by electrostatic discharge (ESD).
You should take precautions to avoid excessive static buildup in your environment.
This can include humidity control and removal of synthetic materials near the phone
location. Antistatic spray applied to carpets in the workplace can reduce the level of
static buildup.
