MOVING ON
Extension
Displays the extension currently assigned to the endpoint. This number is for display
purposes only; it cannot be changed.
Push-To-Talk (Model 8665 only)
The Model 8665 incorporates push-to-talk functionality. PTT may be allowed or dis-
allowed in the Admin menu. If allowed, the user may enable or disable locally, and
may set the channel, tone volume and audio volume. The menu for push-to-talk does
not appear if PTT is disallowed on the Admin menu or if no channel is enabled on the
Admin menu.
Channel
The current channel is displayed. The user may enable any PTT channel that has been
allowed in the Admin menu by entering the corresponding number from the keypad.
If PTT has been enabled in this endpoint, the default channel is the lowest allowed
channel as set in the Admin menu.
Enable/Disable
Enable turns on PTT mode. Disable turns off PTT mode. PTT is disabled by default.
NOTE: If PTT is allowed in the Admin menu and enabled by the user, standby battery
pack life is decreased to about 30 hours.
Audio Volume/Tone Volume
Used to adjust volume of PTT audio and tones. The graduated volume bar indicates
the levels. The Audio Volume setting may be overridden by adjusting volume while
the endpoint is in a push-to-talk call. Select a volume level by pressing the Up and
Down side buttons and then pressing the OK softkey.
