You can use a Plantronics headset with Avaya Workplace Client for Mac and Avaya Workplace Client for Windows to do the following:

• Make calls using the primary line.

• Answer calls on the primary line.

  You cannot answer a call if you receive multiple call alerts.

• Mute or unmute the call.

• Hold or retrieve the call.

  You cannot retrieve a call if there are multiple calls in the on-hold state. Also, you cannot hold the current call if there is already an on-hold call.

• Enter DTMF digits using the keypad.

• End the call.

• Toggle between two active calls. Toggling between calls will hold the current call and retrieve the on-hold call.

• Use mid-call controls on a dual-registration call, a Meet Me conference call, or an Adhoc conference call.

  You cannot start a dual-registration call, a Meet Me conference call, or an Adhoc conference call.
