Upgrading your Snom firmware

Description of Problem

If you want to take full advantage of all Camrivox's CTI features, you need to have a recent version of firmware on your Snom phone. If your version is before 7.3, then you will be missing functionality (the call control buttons in the Flexor Call Summary will be greyed out etc.), and need to upgrade if you require the additional functionality e.g. putting a call on hold from the Flexor Call Summary window. 

snom firmware 7.3 branch, introduces support of CSTA (Computer Supported Telecommunications Applications) : http://wiki.snom.com/CSTA

Please note this new snom firmware also introduces an optional HTTP server Username & Password automatic recommendation for your snom phone, that if set can interfere with communication between your snom phone & Flexor. Current advise from snom is to not set this Username & Password unless the additional security is required. Please see the advice on snom security settings here.
