# Making Voice And Video Calls

Junovy Talk provides high-quality voice and video calling capabilities directly within your conversations. This guide explains how to start and join calls.

## Starting a Call

To start a call from any conversation:

1. Open the conversation you want to call
2. Click the **Start call** button (green phone icon) in the top right corner
3. Choose whether to join with video enabled or just audio
4. The call will start, and other participants will be notified

## Joining a Call

When someone starts a call in a conversation you're a member of:

1. You'll receive a notification (if enabled)
2. Click the notification or open the conversation
3. Click **Join call** to enter the call
4. Select your audio and video preferences before joining

## Device Preview

Before joining a call, you can preview your camera and test your microphone:

1. The device preview appears when you're about to join a call
2. Check that your camera shows your video correctly
3. Speak to test your microphone levels
4. Adjust your camera and microphone selection if needed

You can also enable "Skip device preview before joining a call" in App Settings if you prefer to join calls directly.

## In-Call Controls

During a call, you have access to several controls at the bottom of the screen:

## Push-to-Talk

Use push-to-talk for better control over your microphone:

Share your screen during a call:

1. Click the **Screen share** button
2. Choose to share your entire screen, a specific window, or a browser tab
3. Click **Share** to start sharing
