• The TSG Certified IP phone J179 is a modified version that connects to
your network like any other J179. The difference is the addition of Positive
Disconnect On-Hook Security. The phone also allows the on-hook
security features to be engaged while in a call providing “Hold”
and “Mute” security.
• Special positive-disconnect circuitry and ultra-low-emissions technology
ensure that no audio signals from the microphone are produced on any
wires leaving the phone when it is on-hook.
• When Power over Ethernet is not available, the phone can be plugged
into a local supply that provides filtered operating power via the phone’s
barrel connector.
• Speakerphone functionality is enabled on the device and is protected with
the on-hook security of the positive disconnect electronics but can be
administratively disabled via the Avaya Aura®
 Communication Manager.
