Can people outside our
organization join our Hangouts?
Yes. External clients or customers can join a Hangout even if they don't have a Google Apps account. You also have the option to restrict access to Hangouts to only within your organization.
How many people can join a Hangout?
Up to 15 people can join a Hangout at once, with no time limit. You can also use Hangouts On Air to broadcast a Hangout to as many people as you like (although there is still a limit of 15 active participants).
Is the content of our Hangouts secure?
Yes. All video and audio streams in Hangouts are encrypted. Participants can join securely even if they're not in the office.
What you can do with Hangouts
Break down barriers between remote sites and offices with easy video meetings. You can also choose to make just an audio call or message chat instead.
Video meetings are easy to set up and schedule. Join a meeting from wherever you're working through a Gmail message, a Calendar event, or even directly from any web browser.
