Timesaver: Quickly Ending a Call
Your phone may be set up so that you can end calls by tapping the Line Key. If your system
administrator has enabled this feature, you can end an active call by tapping the Line Key
associated with the call.
Using a Headset
If you use a headset, you can set up your phone so that all calls use your headset. You can also use the
hookswitch button on your headset to place, answer, and end calls.
Note: Using an RJ-9 Headset With Your Phone
If your headset has a RJ-9 modular connector, a separate Headset Jack Adapter (P/N 2457-11095-
002) is required if you want to use it with SoundPoint IP 321 and 331 phones. To purchase the
Headset Jack Adapter, contact your reseller.
Plug the headset RJ-
9 jack into the adapter, and then plug the adapter into the 2.5mm port on the
right side of the phone as shown below. The headset operates as before.
Troubleshooting: Dealing with Electrostatic Discharge
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.
Enabling Headset Memory Mode
This feature is especially useful for permanent or full-time headset users. You can set up your phone so
that all incoming and outgoing calls use your headset. At any time, you can switch to handset or
speakerphone mode.
