The Problem

Twilio recording storage was costing ~$450/month and growing. 929,659 recordings needed to be migrated to cheaper storage without disrupting live operations.

The Solution

  • Built migration pipeline to move recordings from Twilio to Supabase
  • Implemented Supabase resumable uploading via Core API
  • Real-time migration: new recordings migrate from Twilio to Supabase immediately upon call completion
  • All migrated recordings deleted from Twilio storage
  • 868,931 recordings discovered and processed initially
  • 789,456 successfully migrated across multiple agencies
  • Additional 60,728 recordings migrated during the 2-week migration period
