Voip And Packet Switching Technology
By Frank Owen, Sat Dec 10th
One of the reasons VoIP is so successful and advantageous is ituses packet switching technology rather than circuit switchingtechnology to provide phone services. Most phone companies usecircuit switching technology. Packet switching technology isdifferent in that it allows multiple phone calls to occur withinthe same space a single phone call would occupy using a circuitnetwork. This means less transmission time is used and less expense isincurred for the same phone call placed using packet switchingversus circuit switching technology. How does packet switchingwork? Basically you pick up the receiver or initiate a phonecall, which sends a signal. After dialing a phone number thetones are converted into digital data your computer can read andstored temporarily until the VoIP company sends the phone numberyou punch in to their call processor. The processor maps thephone number to an IP
address. That is nothing more thansomeone's computer address, then connects the two computerstogether using a soft switch device. Your Computer and VoIP
Your computer is basically acting as an intermediary, passingvoice messages much like it would an e-mail to another user. Youcan talk for any length of time necessary, and all the whileyour computer and VoIP software will be transmitting datapackets of information from one computer to the other,translating analog information into digital virtuallyautomatically. The entire process takes just seconds and allowsa higher volume of calls than a traditional phone line would.
