Differences between classic Hangouts and Chat
- Group messages in Chat aren't compatible with group messages in classic Hangouts. If you create a group message in Chat with people who don't have Chat, they won’t receive your messages. Hangouts.google.comwill still be available if you need more time to transition group messages to Chat. Learn more about Chat and classic Hangouts interoperability.
- Phone calls and text messages using Google Voice aren't currently available in Chat. Users can make calls and send text messages using Google Voice at voice.google.com or through the Google Voice mobile apps.
- Some classic Hangouts features aren’t currently available in Chat, such as custom status messages.
- The default Chat notification is New threads, threads I'm following, and direct messages, which is different than classic Hangouts. To change their notifications, users can go to chat.google.com/settings.
