I found this article recently - http://voxilla.com/2012/03/02/company-spotlight-obihai-technology-reinventing-voip-a-third-time/ - I had no idea that Obihai's leadership was a major force in the SIP / VOIP technology arena. I have never seen any of this information on the Obihai web site. I guess it's a case of engineers doing their engineering but not necessarily tooting their own horn.
Interesting..........
