While on a call, you can subscribe up to three guest headsets to 
your USB adapter for conferencing. As you add headsets to the 
adapter, an additional headset icon will appear in the Plantronics 
Control Panel with a number from 1 to 3 indicating the number of 
guest headsets subscribed to the adapter. 

Guests may conference in as described below: 

While you are on a call, place the guest’s headset into 
subscription mode.

Short press (less than one second) the subscription button on 
the USB adapter. The USB adapter light will flash yellow and 
green.

  The USB adapter light will then turn solid yellow and you will 

hear a tone in the master headset indicating a guest wishes to 
join the call.

  If you press the call control button on the master headset 

within five seconds, the guest is joined to the call. 

  If you do not press the call control button within five seconds, 

the request to join the call is rejected and the guest will hear an 
error tone in their headset.

  Guests may leave the conference call by pressing their call 

control button. 

  When they do you will hear a single tone in the master headset 

as each guest leaves the call.

To see how many headsets are subscribed to the adapter, refer 
to the lower left-hand corner of the Plantronics Control Panel. 
The first headset is the master headset and the number inside 
the next headset is the number of guest headsets subscribed to 
the adapter. The examples below show 1, then 2, then 3 guest 
headsets subscribed to the adapter in addition to the master 
headset.
