Internet Telephony

03/23/2012

Voice over Internet Protocol (or VoIP, for short) is a set of technologies that uses the internet as the medium to transmit voice. The most popular uses of this technology are video chatting and internet telephony. In this article we will concentrate on the latter.

Internet telephony, therefore, is the implementation of VoIP technology to place and receive phone calls. A VoIP phone may look like a regular phone, but it has been built with special technology to work on Internet Protocol. Another difference between a standard phone and an Internet Phone is that they have an RJ-45 connector (as opposed to standard phones which use RJ-11). This enables the possibility of connecting the phone to a router or switch to be able to place and receive phone calls. A regular phone may be used as an Internet phone when an Analog Telephone Adaptor is set in place.

There are many advantages on implementing VoIP in the business environment. They include:

– Mobility: Internet phones are not bound to a location. Once the phone has been set up, it could be taken anywhere in the world. As long as it is connected to a network, the user will be able to communicate. So if the user were to, for example, leave the country on a business trip, he would be able to take his phone with him around the globe and pay no extra cost for his phone calls (provided he can find where to connect his Internet Phone) and using the same number anywhere in the world.

– Cost: Phone calls made over VoIP are usually cheaper than those placed over standard phone lines. Since the user is using his Internet connection as a medium to transmit the voice, VoIP telephony providers are able to lower the costs for phone calls, even those which are long distance.

– Ease of use: Internet phones have been designed to make tasks such a transferring phone calls and conference phone calls easier.

Along with VoIP, PBX is normally deployed. PBX (short for Private Branch eXchange) allows the creation of private phone networks within a company. Together with internet telephony users are capable of sharing one or more outside lines to communicate, as well as internal communication.
