VoIP as a means for cheap calls is a well established phenomenon, but the benefits of VoIP is not cheap calls, but the number of integrated services that can be built around it. With VoIP voice communication can be a well integrated part of almost any other applications just as e-mail has become. It also allows your phone to behave in the context of where you are, “how you are” or what you are doing (I am Busy, with family, kayaking etc). In the regulated and locked in world of telco operators, most innovation is stopped by either the operators or the operators. One good example is VoiceMail, which IMHO is broken today (I even turned of VoiceMail for my mobile phones). So go innovate new Voice services!
