I always think it’s a good thing to see businesses reduce costs(VOIP is almost always guaranteed cheaper than the old stuff) for of the obvious reasons.
But I don’t see the big deal. Although, it’s great for Asterisk.
FWIW, I myself run a VOIP phone system. It’s great. I got Skype, a skype hardware phone(linksys cit400) and my service is dirt cheap. I get broadband and unlimited phone service for around $30/month.
Asterisk is so much more than just viop... Its call parking, voice mail, interactivity will applications, and things like business continuity cant be ignored.
A solid market provider for mid to small business that is affordable and puts control in their hands will be a revolution for the IT industry..
