Partial A developer-facing API that routes voice and SMS to webhooks is codeable, but it depends on telephony carriers, number provisioning, and compliance such as 10DLC registration, STIR/SHAKEN, and recording rules that AI-assisted coding cannot resolve.
What it would actually take: A realistic version would wrap an existing CPaaS like Twilio, Telnyx, or Plivo for numbers and call legs, then add a real-time media bridge (WebSocket audio streaming with low-latency speech-to-text and TTS) and a webhook dispatcher. The hard parts are carrier relationships, regulatory registrations, fraud and abuse controls, and keeping latency low at scale. This requires telecom and reliability engineering expertise, not just app code.
