Help Google Voice

[imamabella]

My brother just got the Galaxy S3 and he downloaded the Google Voice app and now he cant get it to work on his phone. Before he had to work where it was fine but now it wont ring or txt. Is there anyway he can get it working without losing the number again. We also gone thru the setting but nothing

This is her brother..i had a Evo with Google voice. it worked great. on the evo i could use the app to make calls/txt. also when i made calls i had the option to use either my real # or Google # from a pop up window before calling.
now i upgraded to galaxy s3 installed all my apps from evo. but having problems with Google voice. some reason its thinking my REAL # is my Google voice #. so every time some one calls my REAL # i'm having to press 1 to accept an some times it doesn't work. HOW CAN I FIX THIS i want things back the way they were on my evo
