To get started, All you need to do is set the site URL for the Webex site you want to use for meetings. In any channel, type /webexconfig team [Webex site URL] to set the Webex site that your team will use for meetings - e.g. /webexconfig team teamsite.webex.com

For detailed Webex Meetings app commands, use /webexhelp

If you don't have a Webex account, go to www.webex.com to sign up for an account for you or your company.
