When forwarding GVoice calls to a cell, you have the option to display your GVoice number or the calling number.
If you display your GVoice number, you don't know who is calling.
If you display the callers number, you don't know if they called your cell or GVoice number. [so you know which number to call them back with; especially if you don't want to give out your cell number]
Any way to distinguish that the caller has called your GVoice number and still display their number on the caller id?
