Slack, as you may already know, is a team chatting application. Professionals who are collaborating on a project and are not at a single location use Slack to communicate in real time without using a publicly available chat application like WhatsApp or Facebook Messenger. And up till now only basic text-based chatting was available.
Here is a nice video describing how businesses use Slack to facilitate uniform communication instead of using multiple channels.
Slack is now gradually introducing voice and video calls within the chat interface. This feature needs to be activated by the administrator but once the feature is activated, a tiny phone icon appears within your chat interface and you can do voice and video chatting from your Slack interface.
All the various technology websites are saying that Slack is directly competing with Skype and Google Hangouts, I wonder how this is true. Slack is, if I’m not wrong, basically a work-collaboration tool whereas services like Skype and Google Hangouts are publicly used services. Or maybe what they are trying to say is, up till now, Slack users were using Skype and Google Hangouts whenever there was a need to organize voice and video calls but now since the feature is inbuilt, there will be no use to use these external services. Services like Skype, Google Hangouts, Zoom and Bluejeans can be integrated within the Slack interface, but they require separate installations.
Right now, at the time of writing this, the “Slack Calls” feature began rolling out for the desktop interface and very soon it will also be available for mobile devices. Slack users will also be able to share screens while having conversations.
According to a description of the service present on this TechCrunch link, you can hold private as well as public Slack Calls.
