VoIP (Voice over Internet Protocol) is a term used to describe a group of technologies that are used to connect and deliver voice telephone calls over the Internet.
VoIP telephones can communicate with conventional telephones, and vice-versa. The advantages of VoIP over traditional telephone systems include reduced equipment
cost, reduced phone service cost, an expansive feature set, and the ability to integrate your phone with other computing devices.
Traditional phone calls are made over dedicated telephone circuits; VoIP calls are carried over the Internet. VoIP calls share a data network with other computing devices.
When you place a VoIP call, your speech is digitized at the originating end transmitted as small bundles of data (called “packets”) over the data network and Internet.
At the receiving end, the packets are reassembled into an audio signal. When properly engineered and executed, VoIP call quality is at least as good as or better than a
traditional phone call. However, if the segments of a call are delayed or lost, as can easily happen on a data network, then call quality can suffer.
The Star2Star architecture eliminates this risk with its end-to-end approach that controls both ends of the call path, including automatic prioritization for voice packets over data packets.
