Get call time in Skype for Business

Question

I am using the Microsoft Graph API to collect basic information about a user's meetings and emails. Now, I also want to know how many phone calls (and chats) a user has in Skype for Business and how long the phone calls are.

I realized that Outlook creates a folder 'Conversation History' where these are logged. Unfortunately, not all call entries contain the call duration. I didn't find out when it is there and when not. Does someone know why this is?

And is there a way to get Skype for Business call durations? (I think using the Lync-API (UCMA) might be a bit of an overkill)

Answer 1

I would like this as well. I have added it to the suggestions page for Office 365. https://office365.uservoice.com/forums/273494-outlook-and-calendar/suggestions/13733040-call-duration-for-outgoing-calls-in-conversation-h

Answer 2

The best way is to use the Call detail recording (CDR) database (when enabled). You can find the CDR Scheme here .
