Elixir, Phoenix, and WebRTC - An Enterprise Class Soft Phone in the Browser
summary
Builds a browser soft phone using Elixir and Phoenix with WebRTC and connects into an Asterisk-based PBX; implements a gen_fsm per client for signaling, a proxy that replays state on reload to survive page refresh, and moves ICE and DTLS handling into the Asterisk channel driver so media can flow. Alpha testing is live with beta planned soon. Packaging produces RPMs, licensing limits concurrent clients, headset/device switching is fragile and cost two weeks to stabilise, and earlier Elixir gateways are already in commercial deployments.
