Jeff Pulver – jeffpulver

Wow, what can you say about Jeff Pulver that hasn’t already been said?!?! Well, if you are new to VoIP, here is what you need to know: he is a bit of a pioneer and visionary in the world of VoIP, founder of the one time ‘Pulver media empire’ (which went bankrupt in 2008). Most importantly, Pulver is the chief writer of what’s referred to as “the Pulver Order”, which was adopted in 2004 by the Federal Communications Commission as the first FCC ruling regarding internet protocol communications. The order ruled that computer-to-computer VoIP is not a telecommunications service. He coined the term purple minutes to describe value-added IP network traffic. (from Wikipedia). Now he is working in the world of social communications, unified communications and HD Voice.
