We have started introducing support for AMQP messaging.

AMQP allows us to send notifications about events to other
applications on topics and to receive notifications and commands
over queues.

Example sending a JSON command to reConServer:

   Uncomment the BrokerURL in reConServer.config or any of the other
   reSIProcate applications, repro.config, registrationAgent.config, ...

   BrokerURL = amqp://localhost:5672//queue/sip.reconserver.cmd

   (re)start the reConServer

   Send the command:

   ./tools/send-cmd.py \
     -a localhost:5672/sip.reconserver.cmd \
     -m '{"command":"inviteToRoom","arguments":{"destination":"sip:cisco@10.1.2.3?transport=tcp","room":"room1"}}'

Example receiving messages from the reConServer queue or topic:

   Uncomment the EventTopicURL in reConServer.config or any of the other
   reSIProcate applications, repro.config, registrationAgent.config, ...

   EventTopicURL = amqp://localhost:5672//queue/sip.reconserver.events

   (re)start the reConServer

   Run the utility in the console, messages appear on stdout:

   ./tools/monitor-amqp-queue-topic.py \
