According to Paul D. Kretkowski,

Voice 2.0 is an umbrella term for a loosely defined set of technologies and ideas that let people transmit voice, data, video and instant messages via IP, anytime, from anywhere. It also implies a world where users, rather than a central authority, will have much greater control over who they communicate with, how and when.

He says that the Voice 2.0 applications would bring down telecom bills significantly. However, the implication of Voice 2.0 applications needs a lot of hard works and efforts.

Some of the technocrats consider that we are in the Voice 2.0 era.

Andy has asserted that we are in the Voice 3.0 Era. He claims,

In essence I think we are headed to Voice 3.0, which as pal Jeff Bonforte at Yahoo likes to say, brings 2.0 approaches to a 1.0 world. In my interpretation that’s taking Yahoo Voice or AIM PhoneLine and all they have to offer and applying them to a 1.0 world. That’s where friend and client David Beckemeyer’s PhoneGnome falls in my book. I would have previously thought of them as a 2.0 solution but really PhoneGnome is in the space of bridging both worlds and providing the first and true Voice 3.0 solution even before 2.0 was fully baked.
