Allow users to join a video call by telephone

To allow Hangouts users to invite people to a video call using a mobile or landline telephone number, Google Voice must be enabled in the Google Admin console.

When Google Voice is enabled, users can start a Hangouts video call and click Add Telephone. Phone participants can then participate in the discussion without being on camera.
