I was on a tech support call with a client in Australia for over forty-five minutes. Guess how much that cost me. If I told you less than a dollar, would you believe it? Well it is true indeed.

I called my friend in England just the other day. We talked for about half an hour and it didn’t cost either of us a nickel. Free and clear as crystal, I used my computer. Nothing fancy, just a simple sound card, speakers and microphone is all I needed.

If you haven’t heard about Voice over IP yet, you most definitely will soon. There are several different methods to the crazed digital telephony protocol that could change the way you make calls and save you a bundle.

The current Public Switched Telephone Network is a robust and fairly bulletproof system for delivering phone calls. Phones just work, and we’ve all come to depend on that. On the other hand, computers, e-mail and other related devices are still kind of flaky. Let’s face it — few people really panic when their e-mail goes down for 30 minutes. It’s expected from time to time. On the other hand, a half hour of no dial tone can easily send people into a panic. So what the PSTN may lack in efficiency it more than makes up for in reliability. But the network that makes up the Internet is far more complex and therefore functions within a far greater margin of error. What this all adds up to is one of the major flaws in VoIP: reliability.
