all changes made are ignored and restored if you press the Back context-sensitive soft key.
Presence of USB headset
On the System menu, choose Phone Information, and then select USB to verify the presence of
the USB headset attached to the IP Deskphone. When you select the USB menu, the attached USB
headset is displayed along with other USB devices. The name of the USB device directly appears
from the USB devices themselves. The product description has no explicit USB headset indications
for the attached USB headset. The following figure displays the headset setting screen.

Audio format selection
After the IP Deskphone receives the endpoint configurations, it searches the records to select an
audio format that matches the IP Deskphone requirements. If no match is found, then the default
audio format is used. After you select the format, the IP Deskphone sends a command to the device
to select the corresponding endpoints for audio transfers.
The IP Deskphone supports both 8KHz and 16KHz audio. You can select the 16KHz audio, if the
headset supports it. The IP Deskphone is a mono device with only one voice channel. For stereo
USB headsets detected, the IP Deskphone replicates one channel voice data to both left and right
