Sorry to be rude to you. It's bad timing. There are a number of others who have come around here before you, complaining until they turned blue and insisting that Obihai has done them wrong, that it's a big scheme to sell Obi 200s, and whatnot. And folks here who understand that technology does have a life span, and companies do have to move on, etc., have started to get weary of it.
As for me, I offer a vendor-agnostic Google Voice to SIP gateway service that gets EOL Obi devices and any other SIP device connected to Google Voice. I'm not part of any scheme. I've been offering the service for years.
