You're looking in the wrong place, then.

The problem is that VIPR really provides something more like "random 
failure surprise," as some portion of the call attempts must go over the 
(non-video-capable) PSTN. The user doesn't have any idea about, or 
control over, when this will happen. So while it might be something you 
could use for personal purposes -- where frequent video call setup 
failures would be okay -- I doubt it's a viable video solution in a 
business environment. To run a business, you need something better than 
"random failure surprise".
