Consider the following scenario:
- A Skype meeting is created by using the Meet Now option in Microsoft Skype for Business for Mac.
- A user tries to join the meeting in the Skype for Business for Android or iOS mobile client by using the Call me at feature.
In this scenario, the user can't receive the call.
This issue occurs because one setting isn't enabled in Microsoft Unified Communication Web API (UCWA) for Skype for Business Server 2015.
The issue only occurs in Skype for Business UCWA clients like Skype for Business for Mac, iOS, and Android. The Skype for Business for Windows client users and scheduled Skype meetings won't have this issue.
