Download and install the free video chat program ooVoo through ooVoo's official website. After downloading the program and creating an account, a user can call anyone who has either a phone or ooVoo account. Three-way conference calls can be made using both video chat and voice chat, with the video chat option only being available if the user has a webcam and ooVoo account.
Open ooVoo and sign in to your account with your user name and password, which you receive when you sign up for an account.
Click the "Contacts" tab on the top of the ooVoo window. Double-click the name of the first contact you'd like to call. Once your friend answers the call, the video chat will begin.
Click "Invite" in the upper-right corner of the window. Double-click a second friend's user name to add them to the conversation. It will then be a 3-way chat.
Add someone who has a phone and not an ooVoo account by clicking "Invite" and "Phone." Enter her phone number and click "OK." She will be added to your conversation, without video capabilities.
