Hi,
- If a user is logged into Webex app and is joining the meeting using it then you see their display name but not their number.
- If a user is not logged into Webex App and is joining the meeting as a guest then they have option to choose display name.
In both the cases, you can generate meeting report and find out the email address of a user. This will provide information about who that person is.
Please rate helpful posts and if applicable mark "Accept as a Solution".
Thanks, Vaijanath S.
