So you want to try VOIP, but you don't want to mess around with a home computer network. Can you do it? Easy, if you have an adaptor, which is a VOIP accessory that allows you to create a network bridge between your phone and your Internet service. You can plug the adaptor into your cable or DSL modem and you'll be ready to go. Adaptors aren't super cheap if you have to buy one yourself -- expect to pay $50 or $60. But many VOIP services will give you one for free when you sign up for service.
