Avaya Vantage™ supports standard call control functionalities when you use USB and Bluetooth headsets and speakerphones equipped with call control buttons. These functionalities include answering and ending calls, muting calls, and adjusting call volume.
Note:
When you press the Mute button on a Bluetooth headset, the application UI does not reflect the mute status of the call.
Avaya has not extensively tested other call control buttons, such as Hold and Reject. These functionalities might be available depending on the compatibility of the device.
