Slack's new app integrates Microsoft Teams calling features into its chat app today.
However, you can't take part in Teams calls entirely within Slack, at least for the time being. If you join one from a Slack channel, the call will open up in Teams instead. The Microsoft Teams Calls beta app will only allow Slack users to launch Teams calls from Slack rather than participate in them directly within Slack.
Slack users will be able to set Microsoft Teams Calls as the default calling provider and get to see who’s already on a call and when it kicked off before joining a meeting. Event reminders from the Outlook Slack app will also support the ability to join Microsoft Teams calls direct from Slack.
Slack is also launching VoIP phone integration with Zoom, WebEx, Jabber, RingCentral, and Dialpad. This will allow Slack users to use these VoIP calling providers to call phone numbers directly within the Slack interface.
The new calling features will be available for all Slack users today, and you can already enable the new Microsoft Teams app in Slack from the company’s website.
Slack says it has seen a huge increase in calls made and received through its app in the last month amid the COVID-19 pandemic.
