How can I programatically use Google Voice's "Direct Access Numbers" feature?

Google Voice apps on Android and iPhone have can directly dial out a number that connects to the target number.

This is different than the two ways that I know of connecting a call:

1) use the (undocumented) API to call you first, then GV connects the target party. 2) call the voicemail#, pause, , pause, <2> ,

Both of those methods provide a less than ideal experience.

I know this post is a few months old, but I found it when searching on google. Hopefully this can help some people out.

See this post for details on how to direct dial a number: http://talk.maemo.org/showpost.php?p=756286&postcount=669

See this thread starting around post 658: http://talk.maemo.org/showthread.php?t=41817&highlight=google+voice&page=67

Also, look at the code for the application qgvdial for maemo / symbian. It successfully uses this method to directly dial. Let me know if you have any questions, and I will try to help.
