Hangouts Meet makes it easy to connect with your team from anywhere with easy-to-use video calls. This includes when you're away from your computer, such as when you're traveling or don't have a data connection, and need to telephonically join your meetings on the go.
Now, all meetings created in Google Calendar by users with G Suite Business and G Suite Business licenses will have a US dial-in phone number that anyone can use to join the meeting, even non-G Suite users.
Meetings created by G Suite Enterprise users will also have international phone numbers available. Phone number dial-in was previously only available for meetings set up by G Suite Enterprise users. Note that administrators can disable the dial-in feature in the Administration Console.
