Erlang The Movie II - Back to the Future of Web Telephony

on YouTube ↗26m

" summary

Shows an Erlang Twilio library that converts Twilio webhooks and TwiML into TwiML-to-Erlang records and runs a runtime state machine so Twilio always posts to one URL. Demonstrates an IVR generator that compiles to human‑readable text/HTML, enforces an auto-menu validation that rejects impossible key sequences, and runs conference calls, recordings and transcriptions. Built as spreadsheet-editable recipes and JavaScript client examples; claims quick deployment, low per‑call cost (buy ~1¢, sell ~2¢) and working demos of inbound/outbound call flows.
