Does anyone know what TLS versions are supported by CUCM, Unity Cnx, Contact Centre Express/Enterprise, eg TLS1, 1.1, etc. How do I verify this on the platform?
If they support TLS 1.1 is it possible to disable early versions of the protocol to prevent them from being used, ie TLS 1.0?
Cheers

Hi,
AFAIK TLS v1 for all ver of CUCM and there is no method to disable or enable TLS version on it.You can use the command "show web-security" on the CLI and check what TLS version you have. The same should apply to CUC.

Hi Tere,
Thanks for the info...Heres the show web-security output - I guess the '1' is the TLS version?
admin:show web-security
Certificate:
Data: Version: 1 (0x0)
Do you know if there are any plans to introduce TLS 1.1 or higher. I have a recent PenTest report from one of my clients indicating medium level threats assosiated with TLS 1.0 and man-in-the-middle attatcks.
Regards
Steve
