Slack is a team communication tool founded by Stewart Butterfield. Now the slack comes with a new feature mobile calling; the app already has the option to call using Google Voice, or (shudder); This integration allows you to start a Hangout easily with the members of a channel.
But this new mobile calling feature is now only available to beta users within Android or iOS platforms.

To start a call, you need to open individual or group direct message and click down arrow in the to left corner of the app; now a menu will open with an option Call (user).
