Has EDU VoIP adoption stalled out?

Two of my favorite Google searches are "site:edu voip blog" and the simpler "site:edu voip". The first search helps me find edu-people (faculty and staff) who might be blogging about VoIP. There aren't many. The second search just looks through all of .edu for the term "VoIP."

Maybe I need to add some more parameters to my search, but what I'm finding is a whole lot of the same old. If universities are moving to VoIP, their web sites aren't reflecting it. And I wish some of my counterparts at other universities would share their thoughts in blogs.

While I'm complaining, I'll also mention that Internet2's SIP.edu also seems to be quite stale.

Higher ed and related research institutions and committees invented much of the Internet as we know it today. Is the current generation of higher ed/research doing the same thing with VoIP?
