If VZ Digital Voice isn't VoIP, what is it?
First off, VZ Digital Voice is the name for the [digital] phone service that runs with Verizon FiOS.
Verizon in some areas and situations has a [NON-digital] phone service that runs with Verizon FiOS. It's really POTS with FiOS. And as POTS, there is an extra "FCC Subscriber Line Charge" which does NOT occur with VoIP or with VZ Digital Voice. As the next reference indicates, Verizon is phasing this service out.
»Verizon moves more into true VoIP
Now, contradicting some of the above, why would one maintain that VZ Digital Voice (or AT&T U-Verse's phone service) isn't truly VoIP?
Because it doesn't primarily travel over the public Internet. It goes over discrete (and hopefully discreet) channels.
It rides with the 1 percent, not the 99 percent.
The same can be said of Comcast Digital Voice, Optimum Voice, and so forth....
....True, THERE we are talking about cable, not fiber.
But the point remains that it is not dependent on the riff-raff of the internet.
It's almost a philosophical question. Some people do consider it VoIP, under the feeling that if it's not copper POTS, not cellular, not telepathic, then it's VoIP.
And as I understand it the protocols are not quite the same as common VoIP. More akin to MGCP rather than H.323. But I leave that to the Scotty types.
