Google Voice integration?

I'm new at ZohoCRM and I am in the process of evaluating it as a replacement of my ACT software. I've noticed that it works well with Skype but I would like it to work with Google Voice instead. I admit I haven't spent much time with it but I do not know if this is currently a supported feature. I've seen a post that Google Chrome has an extension that will work with it. Is anyone aware of this? If so could you explain how you set it up and how it is working for you.

Thanks,

Rob
