Obi ATA is not new... I've had one for about a year now
I love it; I have 4 altogether, including one that I am using for Voipo. Never had voice quality problems with Google. There is a very active forum both on obitalk site and on DSLReports; but if you have any questions - I'll be happy to answer.

Not sure what you mean by "impact on resellers". Do you mean companies like Voipo, or (since this is Voipo reseller forum) do you mean Voipo resellers like you?"
