Oct 03, 2016 Question: What version of OpenSSL or TLS is supported by my Poly Phone and can this be changed?

Resolution: Using a CCX as an example you find the SSL / TLS selection via the Web Interface Settings > Network > TLS > TLS Applications. This may depend on the Software version used.

NEW: Since PVOS 8.3.0 or later for Poly Edge E or PVOS 9.2.0 for CCX and compatible Trio Phones

Removal of obsolete SSL and TLS protocols

This release no longer provides compatibility for SSL v2 and v3 and TLS 1.0 and 1.1 backwards compatibility options.

TLS 1.3 is used by default, with a minimum supported TLS version of TLS 1.2 for backwards compatibility.

Support for TLS 1.3

The latest TLS 1.3 standard offers improvements in speed and security of encrypted data. As of this release, TLS 1.3 is always offered when a TLS connection is created, with TLS 1.2 available for far end services that don’t yet support TLS 1.3.

You can configure TLS 1.2 or TLS 1.3 as the minimum protocol version. You can’t disable use of TLS 1.3.
