VOIP Systems

VoIP systems technology is when phone calls travel networks using Internet Protocol (IP). What this means is that the calls are passed through the Internet or privately managed data networks that are using IP to send the calls from one location to the other. So whether the call is passed through the Internet or data networks, the voice stream is broken down into packets, compressed, and sent toward their final destination by several different routes.VoIP Sytems

This is where circuit-switch technology and IP technology differ, in that circuit-switched technology uses a 'permanent' connection for the entire phone call. Once the call reaches the callee, the voice stream packets are reassembled, decompressed, and switched back into a voice stream by several hardware and software elements, depending on the call's final destination. The type of software and hardware needed to start and end a phone call is determined by where the call originated, such as a PC, phone, or an Integrated Access Device (IAD) and whether the call is going to be completed on a PC, telephone, or IAD.
