It’s being advertised asbiggest thing to hittelecommunications market sinceinvention ofcellular telephone, but what is VOIP, how does it work and is it really that revolutionary?
VOIP isacronym for Voice Over Internet Protocol, and it works by using your broadband internet connection to route your call more efficiently and cost effectively than conventional calling. The most common VOIP method works like this. Your standard telephone is connected to VOIP gateway, usually located somewhere in your house likebasement or utility closet. This gateway takes your voice and converts it fromanalog signal todigital signal. Once it exists in digital format it is broken down into smaller more manageable units known as “packets” and is transmitted overinternetsame way data is transmitted to and from your computer. These “packets” contain information about their final destination and have instructions to enable them to be put back together inproper order. Oncepackets reachclosest location to their desired destination they go back through another VOIP gateway which translatessignal back intoanalog format. The gateway then passessignal over toPTSN (Public Telephone Switch Network) and your call is routed tonumber that you dialed.
As people become more familiar and comfortable with VOIP calling newer and more advanced methods of communication will occur. Invery early stages of adoption are IP Based telephones. Instead of using standard telephone equipment withRJfourfive telephone connection toVOIP Gateway these phone interfaces directly withinternet throughstandard network connection. This enable you to use your phone at home unplug it when you leave and then plug it in at your office and your calls are automatically routed tophone wherever it’s plugged in. As WIFI networking becomes more prevalent expect to see wifi compatible cellular phones emerge to make calling even more portable.
While VOIP is still inearly stages of adoption there are still some hurdles that need to be overcome. The most important ones include emergency calling, andneed for uninterruptible power sources. However as VOIP and other IP based telephony continues to grow and advance, VOIP service providers will find ways to solve these problems.
