.It Li incoming calls
|
|
It is assumed that the calling side knows most about charging structures and
|
|
such and as a consequence only the keyword
|
|
.Em idletime-incoming
|
|
has a function for incoming calls.
|
|
.Pp
|
|
For incoming calls the line is constantly monitored, and in case there was
|
|
not traffic taking place for the time in seconds specified by
|
|
.Em idletime-incoming
|
|
the call is closed.
|
|
.Pp
|
|
Typically,
|
|
.Em idletime-incoming
|
|
is used as a last resort and is therefore set much higher than a charging
|
|
unit time: typical values are one to five minutes.
|
|

.It Li outgoing calls
|
|
Outgoing call disconnect time can be setup in one of two ways:

|
.Bl -tag -width shorthold mode -compact
|
|
.It Li simple mode
|
|
For simple mode, the selected
|
|
.Em unitlength
|
|
must be 0 (zero) and
|
|
.Em idletime-outgoing
|
|
greater zero.
|
|
.Pp
|
|
The outgoing traffic is constantly monitored, and in case there was
|
|
not traffic taking place for the time in seconds specified by
|
|
.Em idletime-outgoing
|
|
the call is closed.
|
|
.Pp
|
|
Typical values in simple mode are 10 to 30 seconds.
|
|
|
|
.It Li shorthold mode
|
|
For shorthold mode, the selected
|
|
.Em unitlength
|
|
and
|
|
.Em idletime-outgoing
|
|
must be greater than 0 (zero);
|
|
.Em earlyhangup must be >= 0 (zero).

.Ed
|
|
|
|
During the unchecked window which is (unitlength - (idle-time+earlyhangup))
|
|
in length, no idle check is done. After the unchecked window has ended,
|
|
the line is checked for idle-time length if no traffic takes place. In case
|
|
there was traffic detected in the check-window, the same procedure is restarted
|
|
at the beginning of the next unit. In case no traffic was detected during
|
|
the check-window, the line is closed at the end of the check window.
