Michael Robertson's VOIP Quest

by Mark Evans on Mon 04 Jul 2005 08:15 AM EDT | Permanent Link

Have to say I'm amused by Michael Robertson's latest technology foray - Project Gizmo, which is apparently going after Skype. Robertson believes the masses will adopt Gizmo because it uses SIP rather than proprietary technology. If you're a true entrepreneur, I guess it's easy to overlook the fact Skype has more than 40 million registered users, a global brand, and enthusiastic venture capital backing. Robertson has launched disruptive companies (MP3.com, Lindows/Linspire) but his track record of success is spotty if you're not counting media coverage as "success". Skype's biggest worry isn't new competitors such as Gizmo but the wrath of global carriers that are watching Skype attract more users and more minutes, while piggybacking on their networks. I wish Michael Robertson all the success in the world but, unlike MP3.com, he's late to the party.

I uninstalled Gizmo in about 10 minutes. I was led to believe it worked with any SIP provider but it actually is tied to SipPhone / Gizmo only. So although it is using SIP as a protocol it is just as closed as Skype (at least at this point anyway).

More interesting was my experience dealing with SipPhone. Turned me off completely. I was trying to become a customer and they threw up so many hurdles it was a joke. See this blog entry and the followup.
