Most modern VoIP phones allow to execute certain actions such as dialing or hanging up via HTTP requests. This C2D URL ("click to dial by URL") extension allows you to dial any number supported by your VoIP phone either by manually entering the number in the extension's popup or by simply right clicking onto a previously selected number on any website. If the phone even allows grabbing a screenshot of the phone's display, it will also be shown in the extension's popup. The current version has been successfully tested with SNOM 370 phones. Due to its generic approach, it should work with any other VoIP phone that can be controlled via HTTP requests as well.
