Instagram's direct messaging features has a video chat option available to all users that have the latest version of the app installed on their devices.
The video chat option can accommodate up to eight users and it works with friends who are already on Instagram for iOS or Android and doesn't require a phone number.
If there is an active video chat in a group thread, the camera icon will turn blue and while in the video chat, you can minimise the video in order to browse Instagram, send messages in Direct, post a story, and more.
Tap the message arrow icon in the top right of Feed.
Tap the video icon in the top right.
Select people from the list below or tap Search… to search for someone.
Then tap Start. The person or group called will receive a notification that they are called.
You can video chat as long as you want. When you're done, tap the red phone icon at the bottom. Keep in mind that anyone you've accepted a direct message from can video chat with you. To prevent someone from video calling, you can block them or mute the conversation.
Rooms can also be created to allow you to video chat with other users across Facebook’s platforms, including Facebook Messenger. To create a new video chat room, tap on the video icon in the top right of your Direct inbox and select the people you want to create a room with.
You can manage or/and control your video chat notifications, tap the three lines on your profile and select 'Settings'. From here, select 'Notifications' and then 'Direct messages'. Scroll down to video chats and select your preferences.
