In a Microsoft Skype for Business Server 2015 environment, you use the Skype for Business on Mac client to start or receive a call with a Skype for Business mobile client (iOS, Android, or Windows Phone) user who connects an external network. You may find that the value of Is From user internal or Is To user internal (depending on the mobile user is the caller or callee) always shows Yes on the Call detail recording (CDR) report. It's expected that the mobile clients should be flagged correctly as external or internal on this report.
After you apply this update:
- If the caller uses the Skype for Business on Mac desktop client that connects an external network, the Is From User Internal flag will be marked as No.
If the user of the Skype for Business on Mac desktop client is a callee, or the client is a mobile client, it will keep the original behavior.
In addition, other related issues would be fixed in Skype for Business Server 2015 cumulative update 8 (CU8).
