In a Microsoft Skype for Business Server 2019 environment, you use the Skype for Business on Mac or mobile client that's in an external network to start a call with a Skype for Business client user. You may find that the value of Is From user internal or Is To user internal (depending on whether the UCWA user is the caller or callee) always shows Yes on the Call detail recording (CDR) report. It's expected that the clients should be flagged correctly as external or internal on this report.
