So Best Buy gave it selling VoIP a shot with their purchase of Speakeasy. They sold that to MegaPath.
Now Dell is getting into the VoIP game. For now just in Canada. Read more at Engadget.
I was at the Parallels Summit yesterday. Parallels is a web hosting control panel. The main piece is a BSS/OSS. The second layer is APS, a provisioning engine with XML wrappers for API's to over 350 SAAS companies, including quite a few VoIP companies like 4SPA. Both SIPCOM and Alteva are on the platform offering Hosted PBX and Microsoft Lync.
There's a lot of competition out there. Some are making ordering services stupid easy (like through a control panel on their web hosting account). Yesterday I got to spend about 30 minutes with Guy Kawasaki who said that you either have to be Unique or Valuable. Valuable can mean many things but it could mean being really easy to do business with. Examine your own business to see how easy it is to contact you, call you, order from you. The competition is.
