Webex Teams Calling: when typing a name or device where is it pulling that info from?

[Jason Tintes]

Webex Teams Calling; When trying to call a room or person and you start typing in the Search or dial field, where is that info being pulled from?  Is there a way to tie it to our Endpoints address book? I see it is pulling from Some AD group somewhere but not sure which one.

Webex Teams should be registering to CUCM as a softphone, same as Jabber, and should be pulling user information from UDS.
