D.4
Function 163: Feature set activation
(Generation II only.)
Field 1: Group listen
With this feature disabled: if a station user presses SPEAKER while on a call, the Feature
Phone immediately turns off the handset and switches to hands-free mode.
If enabled, the group listen feature is available system-wide. If disabled, it is no longer available.
Default: Enabled.
Field 2: Privacy release
With this feature enabled: if a station user presses a CO line key that is in use (lit red), the user
will be immediately conferenced with the call in progress on that line. With this feature disabled,
pressing an in-use CO line key has no effect.
Default: Disabled.
Function 165: Auto attendant parameters
Field 1: Auto attendant inter-digit timer
Make this setting higher if callers complain that they don’t have enough time to dial before
either the system sends them to the wrong destination or they hear “Your entry was not valid”;
make it lower if they say it pauses too long after they dial digits.
This sets the time after the first digits has been entered and before the entered number is
accepted as being complete (time between each digit dialed). Expressed in 1/100s of seconds.
Range: 40–1000 (i.e., 400 ms to 10 seconds). Default: 200 (i.e., 2 seconds)
Field 2: Auto attendant no-response timer
Adjust if the time after the playing of the auto attendant greeting is too long (or
too short) before the system follows the no-response (call-forward) destination of a menu
or directory.
Sets auto attendant’s no-response timeout time. This is how long the auto attendant waits until
after the menu plays all options. Expressed in 1/100s of seconds.
Range: 50–6000 (i.e., 500 ms to 1 minute). Default: 300 (i.e., 3 seconds).
Field 3: Fax energy level (CNG tone)
Adjust this level if fax calls aren’t routing properly
when the auto attendant answers. Increasing (or
decreasing) this field causes the system to look for
more (or less) CNG tone to detect whether it’s a
valid tone. This is a threshold level, so setting level
too low may cause the system to route all calls to
the fax port. The energy level of a fax signal must
exceed this setting for more than 200 ms.
Range: 1–32767. Default: 70.
