I had a Canadian Gmail account to which I added a Google Voice account by using HotSpotShield.
My Google Voice account would allow me to enter my Canadian cell number but would not verify it.
I downloaded the 'Google Voice' app from here: »
play.google.com/store/ap ··· glevoiceDuring the install process I entered my Canadian Gmail/Google Voice account & PW. At some point the install displays the phone numbers that you have on the GV account - my cell phone number *did not* appear. On that same page, there is an option to 'Add this phone'. I selected that option and the install finished.
I logged back into my GV account and my Canadian cell number was now VERIFIED.
I tried a call and Google Voice placed it directly from my cell phone - no 'callback' as the 'Voice+' app does.
I just dialed my Google Voice number from my home phone and my cell phone rang!
HTH.
Rob.
