Controlling Calls with Electronic Hookswitch
After you have followed the procedures for connecting your headset and enabled EHS, you can use the 
controls on your headset to answer, mute, and end calls. If supported on your headset, you can also 
place calls on hold. See your headset's user documentation for information on controlling calls from your 
headset.
When you are in an active call and you receive an incoming call, you cannot use the hookswitch control 
on your headset to place the active call on hold and answer the incoming call. Pressing the hookswitch 
control on the headset ends the active call and answers the incoming call. To place the existing call on 
hold and answer the incoming call, answer the call on your phone.
