I use the Microsoft Graph API to gather basic information about user meetings and emails. Now I also want to know how many phone calls (and chats) a user has on Skype for Business and how long they have been calling.
I realized that Outlook creates the Conversation History folder, where they are registered. Unfortunately, not all call records contain a call duration. I did not know when he was there, and when not. Does anyone know why this is?
And is there a way to get Skype for Business call durations? (I think using Lync-API (UCMA) might be a little redundant)
