These a great article from a site called rednova. I never heard of this site but this article gives great insight into Verizon and their VoIP plans. The article consists of an interview with Stuart Elby, Verizon Network Services vice president for Network Architecture.
One of the more interesting quotes attributed to Elby is:
"We're throwing as much out there as we can to see what's going to take,"he says.
It is great to see an entrenched player experimenting. In some ways VoIP makes it easier to play around with new services such as IP Centrex. The article also gives a unique view into the problems that todays VoIP service providers face when rolling out service.
