View your call history in Teams
Your call history is located in the center of the calls experience and shows a list of past calls (including missed calls).
Go to Calls 
> History. From any call in the list, select More actions 
> Call back to begin a call automatically.
You can also chat with that contact, add them to speed dial, and add them to your contacts—all from the More actions menu.
Remove a call from call history
To remove a call from your history:
-
Go to Calls > History.
-
Hover over the call you'd like to remove and select More actions > Remove from view.
Removing a call from your call history removes it from view on all your devices. Admins can still retrieve call data from removed calls.
