It’s easy to make group video calls on Xbox One using Skype. Before you make a group video call, your Kinect sensor must be plugged in. You can initiate a group video call with a friend and then add others for a maximum of 4 people in a group (including yourself). However, if someone else on Skype initiates the call from another device such as a Windows 10 PC, that call can include up to 25 people.
Note You may have difficulty joining some group calls. We recommend that you always initiate group calls when using Xbox One. Functionality may be limited for mobile participants on the call.
