A VoIP (Voice over Internet Protocol) gateway is a device that allows you to make telephone calls over an Internet connection rather than through a regular telephone outlet without having to go through your computer. The device or gateway is plugged into your LAN port or broadband DSL or cable modem. Some gateway devices incorporte dial-up modems for direct connection to phone outlets. You then attach an ordinary cord or cordless telephone to the gateway and make calls just as you would with the plain old telephone system (POTS). On the Internet, your call is carried in packets using Internet Protocol.

Because the gateway bypasses your computer, you can surf the Web at the same time that you or someone else uses your Internet connection for a phone call. No software is required. The gateway can be set up with or without a network router. You can add additional phone lines from the gateway with an RJ-11 splitter.

The major benefit of VoIP is saving money on long-distance charges. However, there are other considerations that make it impractical as the sole telephone service in a household: unlike regular telephone service, if your Internet service is down, your phone will be down along with it, and a power outage means your phone is out as well.
