    • A Brief History of VoIP
      • Invented in 1973 for transmitting voice over the early Internet (ARPANET).
      • Spurred transition from analog to digital transmission in PSTN’s during the 1980s.
        • AT&T
        • Sprint
        • MCI
      • First commercial product: VocalTec Internet Phone in 1996.
        • PC and Sound Card Required
        • VIP to VIP only
        • IP Address for Phone Number
        • No connection to PSTN
        • Poor Audio Quality
      I N T E G R A T E D E N T R P R I S E S O L U T I O N S T E C H N O L O G Y + I M A G I N A T I O N 376 Business Park  3 Nancy Court, Building 1, Suite 1 Wappingers Falls, NY 12590  P 845.226.9983  F 845.226.9987 I E S - N Y . C O M
    • How VoIP Works
      • Your voice is converted from an analog to a digital signal.
      • The digital signal is broken up into packets.
      • The packets are sent to the destination via Internet Protocol (IP).
      • The packets are reassembled into a digital signal at the destination.
      • The digital signal is converted to an analog signal and played back through the receiver.

    • VoIP Functionality
      • The ability to transmit more than one telephone call over the same broadband connection. This can make VoIP a simple way to add an extra telephone line to a home or office.
      • Conference calling, call forwarding, automatic redial, and caller ID; zero- or near-zero-cost features that traditional telecommunication companies normally charge extra for.
      • Secure calls using standardized protocols (such as Secure Real-time Transport Protocol.) Most of the difficulties of creating a secure phone connection over traditional phone lines, like digitizing and digital transmission, are already in place with VoIP. It is only necessary to encrypt and authenticate the existing data stream.
      • Location independence. Only an Internet connection is needed to get a connection to a VoIP provider. For instance, call center agents using VoIP phones can work from anywhere with a sufficiently fast and stable Internet connection.

    • VoIP Functionality (continued)
      • Integration with other services available over the Internet, including video conversation, message or data file exchange in parallel with the conversation, audio conferencing, managing address books, and passing information about whether others (e.g., friends or colleagues) are available to interested parties.
      • Advanced Telephony features such as call routing, screen pops, and IVR implementations are easier and cheaper to implement and integrate. The fact that the phone call is on the same data network as a user's PC opens a new door to possibilities.
      • A major issue preventing VoIP's acceptance by more users is mobility. This is being addressed with new (WiFi)-enabled cordless phones available on the market. With the advent of new technologies such as (WiMAX), it is believed that the mobility issue with VoIP shall vanish.

    • The Future of VoIP
      • Look for VoIP to rapidly evolve in the mobile industry as it has already done so with land-line phones.
      • The integration of VoIP into places that are more convenient for people to access it, such as in web browsers is another innovation to look for.
      • Mobile applications will make VoIP stand out in 2009 such as with Google's Android.
      • The future of VoIP doesn’t show signs of slowing down. As companies continue to develop phones, services and plans that incorporate this technology, the potential of VoIP will only continue to evolve.
