We are using Lync 2010.

In Lync, if a call is not answered, and does not go to voicemail, is anything recorded in the Lync database ?

It looks to me as if nothing is recorded in the database, but I was wondering if there is an option in Lync configuration to make Lync record such activity in its database.

Is there a way to tell from the LYnc database if a call was answered by a person or went to voicemail

I have been looking at the LCSCDR database, at the sessionDetails table, but cannot see a way of distinguising between these scenarios.

Nothing is recorded if the call is not answered and does not go to voicemail.  This is a source of frustration for me, and there is no way that I'm aware of to record this information to the LCSCdr database.

To see if voicemail answered, you want to look at the client version that answered the call, voicemail will say ExchangeUM.  You can see me messing around with this in the below example, pulling from SessionDetails.User2ClientVerId and matching against the ClientVersions table.

Thanks Anthony!
