Does Skype for Business 2016 On Prem support TLS 1.2?

Does Skype for Business 2016 On Prem support TLS 1.2?  How can I find out what version is enabled?

sfb is end of life and no longer supported


How to check if TLS 1.2 is enabled? If the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.2\Client\DisabledByDefault is present, the value should be 0.

Actually we have SFB On Prem 2019. I understand it does support TLS 1 2

My machine shows: 

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\SSL 2.0\Client\DisabledByDefault    (Not TLS)

Does this mean that TLS is not enabled or supported on this machine?

thanks
