true. when the technology is there, the telecom companies should adopt them to make it cheaper for the end user. voip is going to be cheaper for them compared to old generation telecommunications. guess, they are too lazy to invest to upgrade their infrastructure to get the thing going. look at USA, the companies are still stuck on 3g while japan and korea are moving ahead with faster technologies. here in india, we are still stuck on 2g. and mtnl is charging 5 rupees per mb on 3g!
