Release readiness and validation gates

Version 0.0.1: local-only technical preview. The existence of tests, a static site or a hash-chained session receipt does not prove a live phone service. Current evidence is entirely local and fixture-based.

Pre-call qualification is central to the design

The original Windows Dial-Tone uses registered account, OPTIONS, audio and codec checks, a local audible tone, and Call Trace. AI Dial-Tone aims to bring that principle to autonomous agents as authenticated, machine-readable readiness evidence. The optional BYOT connector currently provides only an operator-authenticated, non-dialling PJSIP endpoint-state observation through ARI. online cannot establish routing, remote audio or PSTN reachability. See Pre-call qualification.

What is checked

  • Node.js public-contract checks (npm run check), including synthetic site links and capability claims.
  • Python Peer Lab tests (npm run test:peer), including authentication, media sequence, deadlines and interruption behaviour.
  • Browser laboratory unit/contract tests (cd labs/web-softphone && npm test), plus Python bot tests.
  • Documentation regeneration and clean Git diff of generated files.

What must be independently accepted

  • Genuine two-model natural speech conversations with measured accuracy, latency, interruptions and failure recovery.
  • Isolated Asterisk SIP TLS/certificate policy, authenticated OPTIONS, mandatory encrypted media, real INVITE, RTP and confirmed hangup.
  • Operator-verified and provider-enforced hard cutoff, consent, destination allowlisting, fraud controls, and orphan reconciliation.
  • UK PSTN and regulatory review, real commercial billing, x402 settlement accounting and refund policy.
  • Published operations, customer support, telemetry, privacy/retention and incident response.

Publication of 0.0.1 as research source is different from launching a production calling service. Real telephony remains blocked by all of the above. See Roadmap and the repository's QA-REPORT.md.
