Who Me Too'd this topic

I see that the new CUCM 12.5(1)SU4 has a feature SSO Redirect URI for Webex Apps

One of the improvements that come with it is "Improved calling experience prevents dual login when SSO is enabled while using Webex Client(s) or Unified Communications Manager."

Can someone elaborate on this new feature on how exactly it works and whether it needs specific additional configuration.
