Daily provides developer tools to handle various call scenarios, including issues like participants being muted during a call or dealing with poor network conditions. The company offers a Client SDK and a hosted call component called Daily Prebuilt, which can automatically adjust video and audio quality based on participant's network conditions. To prevent problems from arising in the first place, developers can take steps such as checking the camera, speakers, and microphone are working properly and conducting network tests to manage users' expectations regarding call quality. A great precall experience is crucial for a smooth call experience, and Daily Precall React is an example of how this can be achieved with a user interface that tests input devices and incorporates network testing to identify potential issues before they occur.
