Notes on the telephony layer of a conference-bridge platform built with a small team. FreeSWITCH in Docker, SIP plus WebRTC, a dialplan that curls into the API on every call, and a recording pipeline driven by post-process hooks.

How to handle signals and properly terminate docker service written with the Crystal-lang.

How to configure DigitalOcean's floating IP with VoIP, specifically with Asterisk, using Docker.
