iPhones from Comwave

From comwave.net:

Comwave iPhone™ is a telephone service that that is quite liberating and frees you from the "Phone Company". iPhone uses your High-Speed Internet connection as a phone line. With one internet connection you can enjoy as many phone lines as you like, and you can talk and surf the web at the same time.

How it works. You will recieve a device that looks like an internet modem. This is the iPhone. On the back of the iPhone (click here) are telephone outlets that you use to plug your telephone set just like a regular phone jack at home. You can plug in any type of telephone, even a fax or answering machine.

Each iPhone is capable of supporting 2 independant phone lines (one line for you and one for the kids) and you can attach as many telephone sets as you like.
