"I find it quite amusing that only those who have no experience in the phone business or those who have not tussled with the phone companies are making wild eyed predictions that voice will be free... Port blocking and other traffic grooming techniques which I have written in the past are clearly going to make things difficult for anyone who threatens the incumbents livelihood. What we will see is move away from the billable minutes paradigm to flat rate, which in the end may not be such a bad thing at least for cable companies, who are used to the flat rate life."
