The Voice Over IP Insurrection
Chris Holland writes "Daniel Berninger wrote the most informative article about Voice over IP I've ever read, over at Om Malik's blog. It outlines in great details the history behind the evolution of traditional communication technologies framed within the convergence of various Internet-related technological advances, and the challenges PSTN telcos are facing to hold-on to their shares of this lucrative pie. Beyond mere technological issues, Berninger offers great parallels and insights on past, current, and future governmental regulatory policies. A must read for anyone who's ever talked on the phone."
There are some major problems with VOIP. For example, if you make an emergency call, rescuers can't automatically locate you. Also, it's a lot easier for people to manipulate this technology to make anonymous calls and thereby threaten and harass others. These are things people need to think about before concluding VOID is good for mankind.
Information theory is life. The rest is just the KL divergence.
