Large scale dialers: performance and solutions

Sign up or log in to save this to your schedule and see who's attending!

Mojo Lingo has developed multiple high-throughput outbound dialer solutions based on Asterisk and other components. Over the course of those projects, we acquired a solid knowledge of how to best scale them by utilizing specific configurations, modules, and components such as message queues and Adhearsion. The application layer is then compounded by specific tools that enable us to do autoscaling and real time monitoring, with a focus on self-healing and node recovery. The presentation is about our journey to 1000 calls per second, and will be divided in three sections: numbers and statistics will be presented first, to introduce the discussion. Following that, echnical recommendations will show what our choices were, and how they were made, both inside and around Asterisk. The third section will be an exploration of the load testing and monitoring tooling used during development, from SIPp to higher-level tools... and even Asterisk itself can be very useful as an user agent! Finally, I would like to present our "top 10 scaling tricks" to be applied to any application, not just an outbound dialer. Code and configurations will be available and explained during the presentation.
