Create groups in Skype for Windows Desktop or Skype for Modern Windows to host a three-way voice or audio call. You cannot host a Skype group call if you are using a mobile device, TV or Linux system, but you can participate in audio group calls. Once you've created your group, use the video or audio Call buttons to start the call.
Group Calls on Skype for Windows Desktop
Select "Create New Group..." from the Contacts drop-down menu in Skype.
Click the "Add" button to access a list of your contacts. Check contacts for this group and click "Add to Group" when you have finished. Alternatively, you can drag and drop contacts over to the group. You may name the group by clicking "Empty group" and typing a name. Although you can add up to nine contacts to a group, Skype recommends groups of five or less for the best quality.
