Click to Dial From Chrome (or IE, Firefox)

Reposting same project with more detailed explanations. I need to enable "click to dial" from Chrome using my Elastix (asterix) VoIP server. SipTapi works fine from outlook, and using chrome extension called Skype Links 0.3 I made some progress bot something silly is missing. To be more specific, I need to dial from v-tiger, but I would like not to change elastix or v-tiger for that. I think siptapi with proper use of chrome extension (custom made or this one I found modified) can do this. If any modifications on elastix needed, before moving on, please explain in details what kind of modification has to be made. I consider this simple task if the right person is on it.
