Limitations and Advisories
• USB headsets consume power from the USB port in order to operate.
The USB port on the IP Deskphone imposes a limit of only 100mA.
The limit of 100mA is sufficient to power the Avaya USB
Adapters but is not sufficient to power the wireless headsets
from GN Netcom and Plantronics. Also 100mA is not sufficient
to power the Algo 4900 USB ATA.
• USB Audio support does not include stereo audio.
