VoIP Cable Modem
Voice over Internet Protocol transmits voice signals in real-time over the Internet or IP network using your broadband Internet connection. VoIP works by sending voice information in digital form in packets. You make and receive calls as you would on a regular phone; the only difference is that calls travel over the Internet instead of over a phone line. A number of companies offer voice over Internet protocol. Vonage is the largest in this niche industry with 260,000 phone lines running through its service. Now many cable companies are leaping into the fray by adding VoIP services to their service repertory. Cablevision Systems and Charter Communications, for example, now rely on it for all of their voice services. In their eagerness to provide multi-tiered service, Cox and Comcast offered service over the Public Switched Telephony Network (PSTN). Although initially a network of analog telephone systems, the PSTN is now almost completely digital.
