Make calls in Slack

With Slack calls, you can make a voice or video call to connect with anyone in your workspace. Keep reading to learn how Slack calls work, and the plans and devices they're available on.

Note: Owners and admins can set a third-party calling app as a default calling option. If this is the case in your workspace, clicking the  phone icon may start your call in another app.

Heads up! Slack calls will not be available after March 30, 2023. To have live audio or video conversations with your teammates, try huddles instead.
