I have attempted to port my Google Voice number out to RingCentral (USA) 3 times.
The first time (7June) RingCentral informed me that there was a "Freeze" on the account probably because it was locked. (Not so, I paid for unlocking the phone number hours before submitting the porting request one week earlier).
The second time (14June) RingCentral informed me that the "Information you provided does not match the information on file with your current service provider". (I provided the info exactly as advised by the Google Voice forum.)
The third time (20June) RingCentral informed me that it "could not be completed because the account with BANDWIDTH.COM:979E - NSR/1 has been INACTIVE or CANCELLED even though your line is still working." (Seriously? What the hell does that mean?)
RingCentral points the finger at Google telling me to "call them" and ask for help. RingCentral reps in the transfer department have no clue that there is no telephone answering customer service staff at Google Voice.
A call to Bandwidth.com's support center ( Bandwidth.com/contact) gets a pleasant & willing-to-help (but other wise an unable-to-make-anything-happen) response. They confirm being Google's provider of numbers and bulk phone lines but they only act as the 'non intervening' middle man who receives the porting requests and hands them over to Google (and then passes along the response without alteration).
So, has anyone had success in porting a Google Voice number to RingCentral?
(I see that Allan Thygesen, VP of Global Sales and Operations for Google now sits on RingCentral's Board of Directors - so if they can make the high level connection, how about making a connection at the ground level?!?)
