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 188.8.131.52.
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.
Now is a good time to make sure you have your SRS patching in play before the 28th February if you are a SfB Online or Teams customer.
Lync Room Systems (a.k.a. SRS v1)
Lync Room System (LRS) has reached the end of support on October 9, 2018, and will not be updated to support TLS 1.2.
The following LRS systems will need to be upgraded or replaced if TLS 1.2 support is required
This documentation outlines options to move LRS systems to SRS v2: https://docs.microsoft.com/en-us/skypeforbusiness/deploy/deploy-clients/lrs-migration
