Google Voice API for web apps?

I'd like to allow users of my site to have a list of contacts and click a button beside a user to initiate a Google Voice chat session, exactly like I can in Gmail. I'd like to be able to detect whether the Google Voice browser plugin is installed and use it if it is installed.

Is there a way to interact with the plugin as described? I'm open to similar solutions. I'd like to 开发者_StackOverflow社区not have to route voice server through my server and let the user go directly through Google's Voice servers.

FWIW, I'm using Ruby/Rails for my backend.

I know this is not Ruby, but here is a web PHP API.

However the plugin.... I don't think so. :( sorry.
