An update on Slack calls

Everything you can do in a Slack call can now be done in a huddle. To give organizations one tool for real-time conversations in Slack, all audio, video, and screen sharing capabilities are now unified in huddles. 

What you need to know
  • Slack calls will be available until March 30, 2023. 
  • After March 30, all live audio and video conversations will take place in huddles. 
  • Making calls with third-party apps will remain unchanged and support will continue for any calling app you use in Slack. 
Notes for admins
  • Members of your workspace will see in-product banners with information about switching to huddles whenever they try to make a call.
  • If you’d like, you can turn off Slack calls ahead of March 30 to simplify tool management and encourage huddles usage in your organization.


FAQs

Who can use huddles?

On the free plan, huddles can have a maximum of two participants. On paid plans, huddles can have up to 50 participants, and anyone in a conversation can join a huddle once it starts.

 

How are huddles different from calls?

Huddles allow for informal collaboration in real time, so you’re not limited to talking with only the people you decide to call. Unlike calls, huddles are faster, easier and more informal, and people can join and leave as they please.

 

Do huddles have all of the same features as calls?

Huddles now offer all of the functionality available in Slack calls and more — video, multi-person screen sharing, a dedicated message thread, and reactions, stickers, and effects. Compare the features of calls to huddles below:

What will the calls experience be between now and March 2023?

A few weeks after you have access to the new huddles features, you’ll see notifications in Slack prompting you to try huddles when you attempt to make a call. Slack calls will continue to work until March 30, but will be completely unavailable starting March 31.


Will I still be able to make calls with third-party apps?

Yes. The experience for third-party calling apps will remain unchanged and support will continue for any apps you’ve integrated with Slack.
