I have noticed that the SSL VPN client capability was added to the 7942, 7945, 7962, 7965, and 7975G phones in phone load release 9.0(2). This feature is also supported on the SPA525G phones. The release notes for this phone load release can be found at the URL below:
The SSL VPN client is currently supported on the SPA525G phones on the UC500 platform. When will a 9.0(2) or later phone load for TNP phones be included in the UC500 software pack?
