When a softphone call arrives, you will hear a ring tone in the headset. If you are using a Jabra-supported soft-

you are done. Softphone control requires that you install Jabra PC Suite (described later in this manual)**.
For other softphones, use the native interface on your computer to answer and hang up.
When you are using a supported softphone, the USB controller lights work as indicated to the right.
You also have the
option of rejecting an
incoming call by pressing
and holding the assigned
Soft button. The incoming
call will then be rejected.
