Usage
Enter y to have the system automatically update the time on display
telephones when background maintenance is run (for example, when the
set is plugged in).
Usage
Enter y to change the ringing pattern from internal to external when an
internal station transfers an external call. If most of your calls go through
an attendant, you might want to set this to y, so your users will be able to
distinguish an external call.
Usage
The number of minutes that you enter determines when the trunk will be
disconnected if the Disconnect Supervision-In or Disconnect
Supervision-Out fields on the Trunk Group screen are n.
Enter blank if you do not want Avaya Communication Manager to initiate a
disconnect.
Usage
Enter y to enable this feature on a systemwide basis. When y is entered
in this field, calls to stations unanswered after 50 seconds are dropped.
When n is entered in this field, unanswered calls drop only when the
calling party goes on-hook.
