Basic Call Features
101
To place a call on hold:
1. Press the Hold soft key during a call.
The line key LED flashes green. The LCD screen indicates that the call is on hold.
Note
To resume a held call:
1. Press the Resume soft key.
Multiple Calls on Hold:
If multiple calls are placed on hold, do one of the following:
- Press or to switch between the calls, and then press the Resume soft key to
retrieve the desired call.
- Press the corresponding line key to retrieve the call.
If more than one call is placed on hold, a numbered prompt appears on the LCD screen, for
example "2/3", indicating that this is the second call out of three calls.
Do Not Disturb (DND)
You can use DND to reject incoming calls automatically on the phone. The prompt message "n
New Missed Call(s)" ("n" indicates the number of missed calls, e.g., 1 New Missed Call(s)) will
appear on the LCD screen, and callers will receive a busy message. All calls you receive while
DND is activated are logged to your missed calls list.
Note
The phone will beep softly every 30 seconds to remind you that you still have a call on hold. The
phone ignores engaged audio device (handset or headset) and switches to Speakerphone to play
the hold tone by default. The Speakerphone key will light up for 1 second.
The prompt message will display only if Missed Call Log for the line is enabled. Missed call log is
configurable via web user interface at the path Account->Basic.
You cannot activate or deactivate DND when DND feature is disabled. Contact your system
administrator for more information.
