Ooma has just clarified that they will not offer Google Voice Extensions to users of their traditional Hub product line, but only to those who purchase the new Telo product.
This is despite the fact that the Telo was not even available for months after the original planned release of GVE. GVE was originally slated for spring/summer 2009 with Telo scheduled for a holiday 2009 release.
The Google Voice Extensions was a key feature in my decision to go with Ooma, and was the main reason why I later expanded my system with two Scout units. I find it hard to justify $350 in new equipment just to get features that were announced for my current equipment.
