+Call types provide sensible default settings for different use-cases. We provide the following types out of the box:
+
+- **Default** (`default`) for 1:1 or group calls that use both video and audio
+- **Livestreaming** (`livestream`) to build ultra low latency livestreaming for your app on our global edge network. Broadcast from your phone or RTMP and scale to millions of participants.
+- **Audio room** (`audio_room`) to build audio experiences for your app. You can build basic calling or feature rich experience like Twitter spaces. Audio quality, reliability and scalability is far ahead of competing solutions.
+
+Each of our [SDKs have tutorials specific for each call type](https://getstream.io/video/sdk/). If you want to know the default settings for each of the call types check out the [Built-in call types page](/api/call_types/builtin).
+
+It's possible  to tweak the built-in call types or create new ones.
