Voice over Internet Protocol, also called VoIP, IP Telephony, Internet telephony, Broadband telephony, Broadband Phone and Voice over Broadband is the routing of voice conversations over the Internet or through any other IP-based network. In simpler terms VoIP (Voice over Internet Protocol) is Internet phone service that bypasses your normal local telephone company. Internet VoIP service rings and has a dial tone just like any other telephone, but calls are routed over your Internet connection. VoIP's growing popularity is lowering the cost of phone communication for many homes, and for some, it’s eliminating plain old telephone service (POTS) entirely. Unlike traditional analog telephone signals, which travel through a PSTN (public switched telephone network), VoIP digitizes the speaker's voice and sends it through either cable or DSL broadband Internet connections. An adapter connects your regular telephone to your Internet connection. Many companies, including Vonage, 8x8 and AT&T (CallVantage), typically offer calling within the country for a fixed fee and a low per-minute charge for international. Broadband Internet access (cable or DSL) is required, and regular house phones plug into an analog telephone adapter (ATA) provided by the company or purchased from a third party.
