Call Control is a prepaid application that can be used together with
6 18 Adrian Georgescu
OpenSIPS call_control module and CDRTool rating engine to limit the duration
7 18 Adrian Georgescu
of SIP sessions based on a prepaid balance. It can also be used to limit the
8 18 Adrian Georgescu
duration of any session to a predefined maximum value without debiting a
9 18 Adrian Georgescu
balance.

11 18 Adrian Georgescu
Call Control achieves this by maintaining a timer for each session and
12 18 Adrian Georgescu
sending BYE messages to both SIP end-points, if the session exceeds its
13 18 Adrian Georgescu
maximum session limit or if the Call Control receives a command to
14 37 Adrian Georgescu
forcefully close the call from outside.
