twilio-voice

Purpose

Enable OpenClaw to design, implement, and operate Twilio Programmable Voice in production:

• Build inbound/outbound call flows using TwiML (<Dial>, <Conference>, <Gather>, <Record>, <Say> with Amazon Polly voices).
• Implement IVR state machines with deterministic transitions, retries, and idempotency.
• Operate call recording + transcription pipelines with retention controls and compliance guardrails.
• Integrate SIP Trunking / SIP Interfaces, BYOC (Bring Your Own Carrier), and edge routing.
• Run conferencing at scale (participant management, moderation, recording, events).
• Diagnose and remediate common Twilio Voice failures (auth, invalid numbers, rate limits, carrier issues, webhook retries).

This skill is written for engineers shipping and maintaining production voice systems with strict reliability, observability, and security requirements.
