OpenSIPS 1.5.0 and prepaid support

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.


  • Parallel sessions using one balance per subscriber
  • Support for sessions that have timeout without BYE
  • Support for sessions that have timeout for media (using MediaProxy)
  • Manual session stop from server terminal
  • Overview of ongoing sessions in the web page or server terminal
  • Graceful restart without loosing track of sessions
  • Detailed logging of all performed actions using syslog
  • Web page provisioning for prepaid accounts (using CDRTool)


The software is available as a tar archive at:

For people running Debian testing or unstable there is an official public repository. To use it, add these lines in /etc/apt/sources.list

deb unstable main deb-src unstable main

After that, run:

apt-get update apt-get install callcontrol
