Slack has just launched a video calling feature to make communication among team members more exciting. It is not just one-to-one but also group video calling.
Slack added voice calling early this year and it has seen a huge uptake. So it is expecting that this new video calling feature will help to gain new customers or retain existing customers. This is int he afce of grwoing competition with the recent launch of a similar service from Facebook’s Workplace and Microsoft Teams
According to Slack,
Like with voice calling, it’s simple to get your team on a video call. No need to open a separate app, dial in to a meeting, or share invite links. Anyone on your Slack team can call another person directly, and if you’re on one of Slack’s paid plans, your team can make group video calls with up to 15 people.
Video calling also includes the calls emoji response feature, so without having to unmute, you can use a 
to ask a question, add a ? to show your approval, or ? to thank people for a job well done. These reactions, along with a few others, will display briefly over your video and play a subtle sound.
You can use Slack to make voice and video calls with third party services like Google Hangouts and Zoom.
Video Calls are rolling out over the next few days and will be available on the latest versions of our Slack for Mac and Slack for Windows desktop apps, as well as Google Chrome. On the move? Users on the mobile apps can still join any ongoing video call, but will be limited to sharing and receiving audio.
