Episode Details

Twilio and RingCentral both started from the same premise — voice should leave the proprietary closet and become software. But they built products so different they barely compete. Twilio went full programmatic; RingCentral became a finished appliance. The standard narrative says the legacy mess will eventually collapse into clean APIs. But as this episode explores, the leaks in Twilio's abstraction aren't technical debt — they're jurisdictional. E911, number porting, and messaging registration are law wearing the costume of infrastructure, and law doesn't refactor. If that's right, the divergence is structural, not transitional.
