You can now invite up to 10 participants to join a web conference in progress. These new participants will temporarily join the discussion without becoming members of the bubble. This means you can add participants even if they don't yet have a Rainbow account or are not currently connected, using their phone number. For added convenience, you can invite participants directly from a preview of your call log, dial a number from a dial pad or perform a search by name in Rainbow directories to get the number to dial.
