What it is

Bandwidth operates its own U.S. telephony network and has added Maestro, an AI Bridge, and Voice AI partner program around it. Enterprises route calls through Bandwidth for cost and compliance, and then plug in voice-AI providers (Vapi, Retell, OpenAI Realtime) at the application layer.

Best for: U.S. enterprises needing direct-carrier voice with AI agent integrations.
Watch out for: U.S. heavy; less global than Twilio or Vonage.
