Skype for Business Server 2015 – November 2016 Cumulative Update

This morning i saw that CU4 was released for Skype for Business Server, i knew from the MAC client release there was a new CU coming very soon for Skype for Business and Lync Server 2013. I don’t see anything for Lync Server 2013 yet though. But it seems there a new CU for Skype for Business Server CU4 6.0.9319.272

When looking over the improvements and fixes i don’t see anything related to the MAC client specifically but i do this mentioned “This update enables Location-Based Routing to support the Skype for Business mobile clients” as the MAC client is really a mobile client perhaps this resolves the issues with E911 support for the MAC client. Nothing mentioned about removing the dependency of a reverse proxy for the MAC client and having mobility deployed. Ill have to do some testing i think.

Update 23/11/2016

Whilst reading about the Mac client CU1 update i stumbled across this, which seems to suggest the dependency on mobility is removed for SfB Server and Lync Server 2013 with the latest CUs.

Without Skype for Business Server 2015 CU4 (build 9319.272 or higher, now available) or Lync Server 2013 CU8 HF1 (build 8309.973 or higher, now available), Skype for Business on Mac requires Mobility enablement on the server side. After updating to builds 9317.272 or 8309.973, Mobility enablement will no longer be required.

Improvements and fixes in the November 2016 update

This update enables Location-Based Routing to support the Skype for Business mobile clients. It also fixes the following issues:

Fix and Improvement	Symptom / Cause
3203706 Long silence when you dial into a meeting in Skype for Business Server 2015 that has name recording disabled	Assume that a Microsoft Skype for Business Server 2015 server is experiencing high latency. In this situation, when you dial into a conference, you experience long periods of silence. This is caused by the latency on file I/O operations to the server. Additionally, after you turn off name recording by running the Set-CsDialInConferencingConfiguration -EnableNameRecording $false cmdlet in this situation, you continue to experience the same issue.
3203153 You experience intermittent message delivery delay or failure in Skype for Business Server 2015 Persistent Chat rooms	Typically, this issue occurs in a large Microsoft Skype for Business Server 2015 environment. Cause This issue occurs because a certain task hits an exception that delays regular messages processing or leads to intermittent "503 Service Unavailable" error on Persistent Chat servers.
3203152 Lync Phone Edition telephones cannot put a call on hold if "Music on Hold" feature is disabled	Assume that you set the EnableClientMusicOnHold parameter to false in a Microsoft Skype for Business Server 2015 client policy. When you use a Microsoft Lync Phone Edition telephone, you cannot put a call on hold.
3203148 Front End server of Skype for Business Server 2015 crashes upon restart	Assume that you apply a normalization rule to the address book, and then restart the Front End server of Microsoft Skype for Business Server 2015. In this situation, the RTCSrv.exe service crashes.
3203707 Japanese characters in the subject of a missed call notification message are garbled	Consider the following scenario: Microsoft Skype for Business Server 2015 is integrated with Microsoft Exchange Unified Messaging (UM). Both user A and user B are UM-enabled. User A sends user B an email message that contains Japanese characters in the subject. User B receives the email message, and then moves the mouse point over user A. User B makes a call to user A from the drop-down list next to the phone icon. User A doesn’t answer the call and receives a missed call notification email message. In this scenario, Japanese characters in the subject line of the missed call notification email message are garbled. Cause This issue occurs because the user notification XML file that’s sent by Skype for Business Server is encoded by using US-ASCII instead of UTF8.
