Which is the best phone number provider for AI Voice Agent apps — Twilio, Vonage, or Telnyx?
Hey everyone 👋 I’m building an AI voice agent platform that serves local business owners — roofers, solar companies, and other service businesses. The agent will make and receive real phone calls using virtual numbers (US-based). Right now, I’m comparing Twilio, Vonage, and Telnyx for: - 📞 Call quality & reliability - ⚙️ Integration with AI voice systems (like VAPI, GPT-based agents) - 💸 Cost efficiency (per-minute rates, number rentals, etc.) - 🧰 Developer experience & support If you’ve used any of these for real-time AI calling or voice automation, which one gave you the best overall experience?
