How to turn your OBi20x device into an mini-ITSP for Google Voice trunks

To clarify one point, with this arrangement, a total of 3 gv accounts can be used by the pbx, correct?
Three should be viable, and in some cases even four, although I have not tested either setup.
Azrobert describes several ways to configure an OBi to do this in the following post:

That said, I've always been a bit paranoid about servicing too many GV accounts from one IP address, for the reasons Steve mentions. I have never had a problem with two GV lines terminating on a server, nor would I expect three to be a problem, but I would be hesitant to stack multiple OBis in this configuration behind a single IP address.

I have zero knowledge regarding how GV does this(*)(**) but historically various heuristics to detect interesting usage could miss the frog boil (i.e. smallish (percentage wise?) increases in usage or accounts may fly under the alert threshold, but huge spikes will get one noticed). Perhaps if one's goal is to avoid being noticed one should boil the frog very slowly and not open a call center of thousands of employees tomorrow using GV as a free calling platform (it is unlikely to end well, which is, I think, what SteveInWA is warning *can* happen).
(*) Although Google has published some interesting papers on approaches that they may, or may not, be using for anomaly detection.
(**) And I am highly confident they continually refine their approaches, so the past may no longer be relevant.

Bill, if they actually do look at stats such as how many GV lines are serviced by a given IP, I'm sure they make an exception for your GVGW servers. But they know and understand what you're doing. It's just a shame no one will give you a straight answer up-front as to whether it meets their TOS.

Consider a large apartment complex sharing a single public IP with a NAT. It would have tens, maybe even hundreds of connections to Google from the same IP. Google is probably not shutting them down, and they are not shutting down someone for making three connections from the same Obi device, either.

SteveInWA has apparently read from the Gospel of Google (only available to a select few!) and has given us some information from it here. Not that Google couldn't easily disavow it, but it's a helpful hint.
