# VoxEngine

VoxEngine is the server-side JavaScript runtime that executes every Voximplant
scenario. It exposes classes, namespaces and enums for handling calls, audio
streaming, conferences, ACD, ASR, TTS, push notifications, integrations
with third-party AI vendors (OpenAI, Gemini, Ultravox, Cartesia, Deepgram,
ElevenLabs, Grok, Inworld, Pipecat) and more.

## How this reference is structured

* **Classes** — runtime entities you interact with: `Call`, `Player`,
  `Recorder`, `Conference`, `ACDRequest`, `StreamingAgent`, and friends.
* **Enums** — event name collections (`CallEvents`, `PlayerEvents`, …) and
  option enums (`CallAudioQuality`, `DTMFType`, …).
* **Namespaces** — module-scoped APIs you opt into with
  `require(Modules.<Name>)` (`AI`, `Net`, `Crypto`, `Logger`,
  `ApplicationStorage`, the vendor namespaces, etc.).

Each page lists the methods, properties and events of the symbol, plus every
`@example` that ships in the TypeScript declarations.

## Source of truth

This reference is generated verbatim from the `voxengine.d.ts` typings file
that ships with every scenario runtime:

```
https://cdn.voximplant.com/voxengine_typings/voxengine.d.ts
```

If you spot a discrepancy between this reference and the runtime behaviour,
the typings file is authoritative and the page will be regenerated on the
next update.
