Voice and video calls are available from direct messages on any Slack plan. To start a call from a group DM or a channel, a workspace must be on one of Slack’s paid plans. To make a call from a direct message, simply click the phone icon at the top right and the call will start immediately. Click the video icon for a video call.
“It works great,” Van Tonder said. He adds that it has allowed AWA Digital to move away from Skype for internal group calls with team members located around the world.
In group calls, you click the phone or video icon and will then be prompted to give the call a name. Anyone in the channel can join the call. Up to 15 people can join group calls in paid Slack plans.
In either case, someone who has Slack set to “do not disturb” will receive a notification of a missed call.
