 Description: Call Control prepaid application for OpenSIPS
  Call Control is a prepaid application that can be used together with
  OpenSIPS call_control module and CDRTool rating engine to limit the duration
  of SIP sessions based on a prepaid balance. It can also be used to limit the
  duration of any session to a predefined maximum value without debiting a
  balance.
  .
  Call Control achieves this by maintaining a timer for each session and
  sending BYE messages to both SIP end-points, if the session exceeds its
  maximum session limit or if the Call Control receives a command to
  forcefully close the call from outside.
