Thanks for all the quick responses.
I think i figured it out.
If the google voice number was used with pbex or sipgate, it will not get incoming calls but make outgoing calls.
I tested this by using a fresh new account that was not setup with any pbex or sipgate and it worked.
Just note that there is a wake issue when receiving calls on 3g or wifi.
