Simple URLs will be sent to your users and used by them to access the web pages for dial-in conferencing phone numbers, meetings, and administration. The active URL is used when new meetings are scheduled. Other URLs are used to support any meetings that have been scheduled in the past by using those URLs. Meeting and Phone access simple URLs are required and must be full URLs, including https://. If you change a Meeting or Phone access URL after it has been published, you prevent users from joining existing meetings or conferences. To change the active URL, create a new active URL and leave the current URL inactive. An inactive URL can be removed after all conferences or meetings that use it have expired or been deleted.
