For those running SRS with Teams, be sure to get them patched to the latest so that they 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. Now they do support TLS 1.2
The latest date Microsoft moving to TLS 1.2 is now February 28th 2019.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.
