Part 1 of this series covered VoIP basics and introduced the topic of Quality of Service. This time, we look at Traffic Shaping and Power Considerations.

Sometimes you just need an operator. It's not often, but there are services that a real, live operator can perform that you just don't get when you subscribe to one of the popular VOIP services such as Vonage. Of course, you're not gong to make collect calls from your VOIP line, and international calls likewise need no operator intervention. But what happens if you need to check the status of a line? That was the scenario I recently faced.
