VoIP is a method or transmission technique for sending voice data over the internet. There are many advantages to this digital data transmission technique, starting with the lower cost of making phone calls using Voice over IP phones. As long as the user has internet, the broadband phone or software based service will work and does not need the normal landline and instrument required by traditional telephony networks.

Technology: The technology is based on converting voice signals that are analog into digital packet data that conforms to the Internet Protocol or IP. These digital packets can then be transferred over packet-switched networks such as the internet, and other LAN and WAN networks. At the other end, the digital packet data is again decoded and converted back to analog signals.

These Voice over Internet Protocol (Voice over IP or VoIP) telephony service providers bypass the traditional public switched telephone network (PSTN) infrastructure used by the old telcos. Instead, all their data is sent and received via the internet and on to special broadband phones. The phone can patch in to the broadband connection and has voice codecs to convert and decode voice data from analog to digital packets and vice-versa.

The user is required to have an ADSL modem and internet line, along with an active internet account with a local ISP. In other words, there should be broadband internet available for use. The VoIP phone looks just like a cordless phone, although it can also be software installed on a computer and used with the mike and earphones of a headset.

Usage: A computer is not necessarily required to operate the phone, if the broadband phone is purchased. Note that a computer may still be needed once for the initial installation and configuration of the phone. Apart from buying the high-tech phone, using Voice over IP is about the same as using a landline phone – just dial, talk and listen, and hang up when the conversation is over.

Features: VoIP phones offer most of the standard services and features available to subscribers of normal land lines and mobile phone networks. This includes caller ID, voice mail, call waiting, forwarding and transfers, three-way calls, etc. Accounts can be managed online, and the calls made with prepaid credits and topups, or postpaid on a monthly basis.

Calling rates: The biggest benefit is that calls made between two Voice over IP phones from the same provider are always free. This is basically equivalent to two computers talking to each other on the internet using the same chat software, which doesn\’t need anything except the internet. This feature will be increasingly beneficial as more people start using these phones.

Even calls made to landline or mobile phones outside the provider\’s network are a lot cheaper. National and international calling rates for VoIP can even be 50% lower than landline rates. The costs of using Voice over IP phones will go down even more once traditional telecom companies start routing the majority of their voice data through the internet to reduce the cost and load on their old congested networks.
