AstriCon 2017

Janus is an open source WebRTC server that was conceived to be modular in nature, a bit like Asterisk itself. It has a core that takes care of all the WebRTC suite, and different plugins that can take care of the Janus API transports and how to handle media in different ways, e.g., WebRTC SFU/MCU, RTP-to-WebRTC broadcasting, SIP gatewaying, recording and so on. One particularly common scenario is using it as a WebRTC gateway in front of Asterisk servers. While Asterisk has good support for WebRTC by itself, there may be cases when unencumbering it from any WebRTC-related effort, and leverage such a gateway instead to let Asterisk focus on the rest, might be helpful, and this talk is aimed at discussing exactly those. Different approaches and possible topologies will be presented, together with real examples of how Janus and Asterisk are used together in the wild today (e.g., to stream IETF meetings).
