"The Linksys WRT54GP2A-AT Wireless-G Broadband Router is really four devices in one. First, there's the Wireless Access Point, which lets you connect both Wireless-G and Wireless-B devices to the network. Second, there's a built-in 4-port full-duplex 10/100 Switch to connect your wired-Ethernet devices together. Third, there is a Router function to lets your whole network share a high-speed Internet connection.

The fourth and most unique function is the VoIP phone adapter which enables high-quality feature-rich VoIP Service through your high-speed connection even while you're surfing the Internet. The router features two standard telephone jacks, each operating independently - like having two phone lines."
