1000 is the max number of participants for a webinar but there should be a 'webcast' option that will handle up to 3000 participants. When creating a new 'live' session, there should be two option at the bottom during creation - 'Standard' and 'Webcast'. Choose Webcast for the larger group.
If you don't see the webcast option or it is not showing the 3000 participant limit, you should reach out to GTW's account and billing team to confirm your enterprise plan's features.
