After you select the format and the Set Interface command is sent, the USB headset runs in Generic
Mode 1 operation (both audio and HID) or Mode 2 operation (audio only). If the headset runs in
Mode 1 operation, the IP Deskphone configures the task or callback to communicate with the USB
HID control events between the IP Deskphone and the headset. You can insert the headset during
an active call. The IP Deskphone synchronizes the headset state machine of the IP Deskphone to
the current state of the headset to ensure the LED match status.
During the call, if the audio negotiated between the two parties is set to 8KHz audio and the IP
Deskphone is setup for 16KHz USB Headset audio, the IP Deskphone performs the transcoding
between 8KHz audio to 16KHz audio. Likewise, if the audio negotiated between the two parties is
set to 16KHz audio and the headset supports only 8KHz audio, the IP Deskphone performs the
transcoding between 16KHz audio to 8KHz audio.

Generic USB headset

When a generic USB headset (or supported headset with HID command disabled) is attached to the
IP Deskphone and selected, it behaves like a wired headset. All call controls, on hook, off hook,
mute, volume up, and volume down are performed using the keys on the IP Deskphone. The IP
Deskphone does not use the User interface elements on the headset, including LEDs if present.
When the USB headset is selected, the voice path to or from the USB headset is used in an active
call.
