1. Open a chat with the person you want to call.
2. Click the phone for a voice call or the camera for a video call.
3. Allow your browser to use the microphone (and the camera for video) when it asks.

During the call you can mute the microphone, turn the camera off and hang up. Calls are end-to-end encrypted.

Calls ring on the Wiply tab you are using and in the Narendi app. Group video calls are coming later.
