Exotel AgentStream Voice Streaming API is one of 6 APIs that [Exotel](https://apis.io/providers/exotel/) publishes on the [APIs.io](https://apis.io/) network, described by an AsyncAPI event-driven specification. Tagged areas include WebSocket, Voice Streaming, Voicebot, and Real-Time. The published artifact set on APIs.io includes API documentation and an AsyncAPI specification.

Documented WebSocket (wss://) voice-streaming API. When a call reaches a Voicebot or Stream applet, Exotel opens a secure WebSocket to your endpoint and streams base64 linear-PCM audio in ~100 ms frames (connected/start/media/dtmf/mark/stop); the Voicebot applet is bidirectional so your server sends media/mark/clear back to speak to the caller and barge in. Exotel is the WebSocket client; you host the endpoint.
