# Pre-conference Included in the base price of the conference. A pre-conference is included with all conferences by default and can be either 15 or 30 minutes in length. Additional time billed in 30-minute increments. The conference is open to speakers 15 or 30 minutes before the start time for you and your speakers to discuss, plan, coordinate, or ask the operator any questions. The operator joins this pre-conference and assists with sound checks, confirms conference details, and reviews the opening script before the event starts.
