Suggestions for a Home VOIP Provider?

nate1138 asks: "My wife and I recently relocated so that I could take a promising position with a better company. Her job, being the fairly progressive folks that they are, graciously agreed to let her telecommute. Most of the services she needs we already have set up, such as the VPN, and VNC for remote control, etc. Now we only have one thing left to do. Get a phone line. Her office is a long distance call from our new location, and she needs to be able to call customers throughout the southeast as well. Since we need a number with a different area code from our home, it looks like voice over IP is the only solution. I want to know what you folks think about the various VOIP providers, like Packet8, Vonage, and Broadvoice. Or any other that I haven't thought of. Or another way to solve the same problem without shelling out a boatload o' cash. Features are the last priority, while reliability is tops."
