Can't join an application sharing session of meeting in Skype for Business Server 2015 that has May 2017 update applied

A következőkre vonatkozik: Skype for Business Server 2015


Consider the following scenario:

  • You apply May 2017 cumulative update for Microsoft Skype for Business Server 2015.
  • Some Video-based Screen Sharing (VbSS) supported clients and legacy clients are in a Skype for Business meeting.

In this scenario, you might be unable to join the application sharing session of the meeting.


This issue occurs because Skype for Business Application Sharing Server (ASMCU) doesn't include the rtcp-mux attribute in the Session Description Protocol (SDP) after the application sharing session is failed from VbSS to the remote desktop protocol (RDP) session.
