What is SIP-based VoIP?

SIP (Session Initiation Protocol) is an application-layer protocol for initiating, modifying, and terminating an interactive user session that involves multimedia elements such as video, voice, instant messaging, online games, and virtual reality. In other words, itís the handshaking system used for sending and receiving data files over the Internet. SIP is an open standard which allows for greater interoperability between SIP-based service providers.

SIP-based VoIP adapters connect your existing telephone to the Internet through a piece of hardware, usually a router, telephone adapter, or IP phone. It requires a paid subscription to a service provider, such as Vonage® or AT&T CallVantageSM.
