Disable TLS 1.0 on VCS / Expressway

[William Kok]

Hi There,

For the Bug CSCuz16292

Disable backward compatibility for TLS version 1.0

https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuz16292/?referring_site=bugquickviewredir

Does anyone know how to disable the TLS v1 on the VCS / expressway?

Regards,

William

Hi William,

This option is available in x8.8 as per an internal bug.  VCS x8.8 includes a way to select the TLS version to be used in SIP communications. Please log in via SSH (with PUTTY) and try the command

xConfiguration SIP Advanced SipTlsVersions ?

It will offer the options ( TLSv1.1:TLSv1.2)
