What is VoIP?

VoIP, or Voice-Over-Internet Protocol, is literally a phone call placed via an internet connection. VoIP has been a long time coming and early internet phone calls were not that reliable and a bit garbled. But they were free. Over the last decade, VoIP has increasingly made its way into business and is now making its way into more and more homes, as people find better, more affordable ways to communicate with convenience.

An internet protocol is a way in which data is handled over networks. It is typically a standard method for passing data from one point to another point via network cable. Voice-Over-Internet protocol is the method by which one's voice is translated from an analog signal to digital 1s and 0s then transported over broadband network connections, often still for a fraction of the cost of long distance phone calls.

Advantages

According to many experts VoIP is expected to be the phone protocol of choice for the future, alongside the ubiquitous wireless calls. VoIP is flexible, and affordable. As long as one has an internet connection, some free or inexpensive VoIP software on their PC, and a microphone, VoIP is viable. It is a simple communication method to setup. The major phone companies already use the technology that makes VoIP possible. They must move large bundles of long distance digital data known as packet switching quickly and conveniently.

One of the most attractive advantages to VoIP is the ability to receive internet phone calls anywhere you are, as long as you are accessible to the internet. Like wireless technology, this frees you from the constraints posed by a phone line connected to a wall jack.

What You Need

There are a number of ways to currently use VoIP. The easiest and least expensive by far is the PC-to-PC connection. Requirements are a PC that is connected to the internet, preferably with a cable or DSL connection; a microphone, speakers, and VoIP software that can still be had inexpensively, even free in many cases.

An increasingly popular method for VoIP is the use of the proprietary VoIP phones that are becoming a standard for many businesses. Companies such as IBM and Cisco Systems are well known for their VoIP phone systems that are designed to become a seamless addition to any large or small business network. Many bundle video along with them making long-distance conferencing effective and affordable for business.

Disadvantages

Currently, the disadvantages to VoIP are the reliability of packet switching technology to seamlessly transport important voice data streaming, real time conversations over the long haul of network cable. Businesses that rely on such technology must be willing to accept the risks involved with poor internet connections, lost signals, and dropped data packets. The internet as a real time communication tool is still in relative infancy in comparison to the technology behind the analog telephone system that has been in existence for well over a century.
