Limitations and Advisories
•USB headsets consume power from the USB port in order to operate. The USB port on the IP Phone imposes a limit of only 100mA. The limit of 100mA is sufficient to power the Nortel USB Adapters but is not sufficient to power the wireless headsets from GN Netcom an Plantronics. Also 100mA is not sufficient to power the Algo 4900 USB ATA.
•USB Audio support does not include stereo audio.
•Changes have occurred regarding the provisioning of Bluetooth on the IP phone 1140E and 1150E. With UNIStim 3.1, the Bluetooth setup page no longer provides the option to select Bluetooth
