Ed,

I am not sure what went on in previous versions of maemo at the time of Nokia 770 or other pre-historic creatures. Here, all you need is GV login info. without even getting close to framework limitations. Call back number or forwarding is set within Google Voice settings - there is no need for it in your program.

Simplicity with least amount of (required, as opposed to optional) user decisions is what makes that apple product (i-what?) with its "apps" so ridiculously popular while we are stuck with complications, confusions and limitations of using such a great device as N900.

For me, your application and using GV is the core aspect when using N900 for mobile communication.

Good luck collecting the always-nice-to-have clean user statistics.
