What is VoIP?
VoIP stands for Voice over Internet Protocol.
It is also referred to as IP phone, IP Telephony,
Internet Calling and Telephony. VoIP started rolling
out in early 2000 and is now virtually everywhere.
The "Legacy" analog phones and phone systems are becoming obsolete. CTI provides all the services to help you make this transition.
From a purely technical sense, one must consider the way the PSTN (Public Service Telephone Network) handles telephone calls now. Each call is set up and delivered from a pair of dedicated copper wires from the caller to the called party. This creates a dedicated physical connection for a single call with extremely good quality. The technology is sufficient to carry one call at a time over the pair of dedicated copper wires. (We are keeping it simple here folks; don't worry about TDM for now)
VoIP packetizes the voice turning it into data packets. These packets are then sent to the network. The same copper wire is now capable of carrying significantly more than one conversation. The same device used to send voice is also capable of sending other packetized information simultaneously like data, video and instant messages. So at the very least VoIP is a much more efficient medium to transport voice, and at the very best, will produce a much richer experience for the user when one considers the enhanced features of video and instant messaging.
VoIP has a lot of advantages over the traditional phone system. The main reason for which people are so massively turning to VoIP technology is the cost. In businesses, VoIP is a way to cut down communication cost and add more features for communicating with employees and customers.
