Hi SFNetworks,
Welcome to HP Poly community!

You can conference up to three additional headsets to a call in progress.

Join a Conference Call 

• While in an active link between the primary headset and the base (on a call), 
• Place the guest headset into the primary user’s charge cradle (this connects the headset to the base). 
• The base subscription LED will begin flashing. After a few moments, the primary user will hear a triple tone in their headset indicating the guest headset wishes to join the call. Within ten seconds of hearing the triple tone, press the primary headset’s call button to accept the guest headset. 
• If the process fails or times out because the button was not pressed within ten seconds the guest subscription is terminated, and the guest will hear an error tone in their headset. To connect a guest headset that is of different variety than the primary headset press the base subscription button while the base has an active link. Next, press the guest headset volume up button until the indicator light turns on. The base subscription LED will begin flashing, and the primary user will hear a triple tone in their headset indicating the guest headset wishes to join the call. Within ten seconds of hearing the triple tone, press the primary headset’s call button to accept the guest headset. If the process fails or times out because the button was not pressed within ten seconds the guest subscription is terminated, and the guest will hear an error tone in their headset. 

Exit a Conference Call 
To remove a guest headset, press the guest headset’s call button or dock the primary user’s headset in the charge cradle. A single tone in the master headset will be heard as each guest leaves the call.

NOTE:

1. Headsets in a conference maintain independent mute controls. The base only indicates the primary user’s mute state. 
2. The user of the primary headset in a multiple headset conference scenario may hear additional tones (triple tones) in their headset and see the subscription LED on the base flash as guest headsets join the call. These additional tones and flashing LED indicate that the guest headset has a different version of firmware as the primary headset, but can still be used for conferencing.

I hope this helps!
