Kenn Leth Hansen - 007: How we build a Telco-grade voice platform on open-source

We've recently completed a redo of all infrastructure and code for our mobile voice platform used by more than 350,000 users. In this talk I'll present how we've build and deployed the platform on open-source software (and what we learned along the way) using web scale approach and automation. This talk will be build up like a war story, setting the scene and background for the audience and telling the story on how we made it in the end. Spiced with stores of some of the crazy stuff we lived through during the implementation and deployment (what we learned along the way). The platform serves 350,000 users carrying an intense amount of traffic every day. We serve everything from plain end-to-end phone calls to complicated set-ups with IVRs, call recording, voicemail, etc. and I'll explain how we are taking on big players like Cisco UCM and bring this functionality the users smartphone. I'll touch how we as a telecommunications service provider are using well-known software within the community like Freeswitch, Kamailio, Homer, Node.js, Saltstack, etc. to deliver a Telco-grade experience to our customers in a large-scale setup. The topics I'll touch in this talk are all related to the (total) redo of our mobile voice platform. It won't be a deep-dive into a specific project or technology but more showing how you can stitch it all together and build a great platform. Some of the topics are: How and why we build new infrastructure from the ground up (build to scale, web scale architecture, automation) How we are interfacing with the mobile network Why the old platform was considered end of life How we now are treating every single call as a conference How we do call processing and provide intelligent features with the new platform How we deployed the new platform without the users noticing
