Please start supporting the latest version firmware for the Cisco 8861 phones. Besides improving call quality with headsets, and features, it corrects many security vulnerabilities. The only officially version that RC supports (11.1) is riddled with security vulnerabilities. Cisco recommends to upgrade to 11.3.x to mitigate these security risks. Also, Version 11.1 cannot be managed by modern browsers any longer, now that it is approximately 4 years old.
