It’s a module that give a Kamailio admin access to the popular message queue system Rabbit MQ from the configuration script.

The module is a result of a joint development project between Carsten Bock and Stefan Mititelu. If offers AMQP communication from kamailio.cfg using librabbitmq, allowing Kamailio to interact with other applications (or Kamailio servers) using a well establish message queuing mechanism.
