Skype Room Systems V2 now support TLS 1.2, but LRS Systems are end of support will not support TLS 1.2


When Microsoft originally announced moving Office 365 to enforce TLS 1.2, one of the blockers was Skype Room Systems using only TLS 1.0 or 1.1.

The latest date Microsoft moving to TLS 1.2 is now February 28th 2019.

Skype Room Systems v2

Good news on the Skype Room System v2 front. Skype Room System V2 software supports TLS 1.2 protocol since December 14, 2018, with app version

Enabling communication over TLS 1.2 for Skype Room System V2 requires Skype for Business Server 2015 Cumulative Update 9 (CU9) or Skype for Business Server 2019 Cumulative Update 1 (CU1). For SfB Online or Teams no specific actions are required.
