One big advantage to VOIP services is that, essentailly, any number is a local number. So this means that when traveling -- for business or pleasure -- you can make local calls with your laptop computer acting as your Internet phone. What you need is a service -- or an extension of your current service -- that allows you to access your VOIP service from any Internet connection. Then all you have to do is plug a headset into your laptop and it becomes your Internet phone. It's like you're sitting in your home or office -- no matter where you are actually located.
