Below is a link to a QS Action I made to dial phone numbers entered in the QS Text Window out through Google Voice. Use is simple enough. Installation takes a few steps. There's a php script included that needs to installed somewhere on your mac. And a couple easy changes need to be made to the applescript action (typing in your username, password, phone number, and where you put the php script). There's better instructions in the zip file. And if you're involved enough with QS to be reading this installation should be a breeze...
