I posted about this back in October. Nobody has the OBi212 in stock, though Amazon was selling mislabeled 202s for a while (I had to send two of those back). They finally updated the listing a week or so ago to indicate they are in fact 202s. B&H also says discontinued and Newegg says out of stock.
In one of my posts that got deleted (not by me), SteveinWA said they would have stock again by end of November (apparently under Polycom branding).
