Using a Remote Direct Connect Button
If you are using a headset or other optional accessory with a remote Direct Connect button, you can use the remote Direct Connect button for phone calls, Direct Connect calls, and Group Connect calls.
For phone calls, use the remote Direct Connect button to answer calls, switch between calls, and end calls. Hold the remote Direct Connect button for less than two seconds to answer calls and switch between calls. Hold the remote Direct Connect button for more than two seconds to end calls.
For Direct Connect calls and Group Connect calls, use the remote Direct Connect button as you would the Direct Connect button on your phone.
When using a headset, the Direct Connect button on your phone works the same way as when you are not using a headset. Direct Connect and Group Connect sounds will be heard through the headset.
