The year just started and a new module was merged into Kamailio git master branch, respectively mqtt:
It has been contributed by Thomas Weber from pascom.net, who has become a registered developer with commit access rights for Kamailio project.
The MQTT module allows bidirectional publish/subscribe communication by connecting Kamailio to a MQTT Broker. Messages can be published from any point in the routing script. Also the subscriptions can be fully controlled by scripting commands.
Enjoy!
Thanks for flying Kamailio!
