VoIP as a technology has become one of the most essential aspects in business communication. In this post, we will look back how this technology solutions of recent times.


The Beginning


It was during the time when black screened Window 3.x prevailed in desktop computers and Internet usage was limited to a particular stratum. People, at that very point of time, were in search for cheaper and more  effective model of voice communication. Land-line telephones were there at every residence and cellular phones had just ushered into the scenes, but they had their own set of pros and cons. The cellular network was not up to the mark and the call rates were high. With the usherance of Windows 95 and increased popularity of the internet, e-mail and web chatting became popular communication medium. This was the time when developers realized the true potential of sending electronic data over the internet at a cheaper charge. Telecommunication started evolving!




A telephonic system with all-inclusive features required an enterprise to spend some million dollars. With emergence of Internet, sending digitized data and pictures became a viable option which was cheaper than traditional telephone calls/conference calls. With further development, it was realized that voice based calls over the internet could not be sent using a regular switchboard, as it would only produce a glorified and more expensive version of the telephone. The focus thus shifted how data travel over the internet. It was realized that data travelled in forms of small packets which get transferred to the recipient in real time. It was deduced that the voice could be sent over the internet the same way data travelled.


VoIP Arrives


VoIP, for the first time, was perfected by an Israeli company known as ‘Internet Phone’. The most basic version of VoIP required both the caller and the recipient to download their software, which would access a server, built exclusively to handle voice packets. The users also had to install sound cards and purchase microphones in order to execute the call successfully. Even though the initial VoIP technology had some issues such as delayed conversation and voice breaks, it was hailed as an achievement. In 1998, Windows 98 came up and it allowed developers to code and create a stable version of the VoIP software which could convert the digital calls to analog calls, allowing users to connect directly to the Public Switched Telephone Network or PSTN while giving them access to land phones and cell phones. VoIP required expensive hardware but then it was worth it, when compared to calls made to/from land phones and cell phones.


VoIP has benefited small businesses not only because of the cost factor which is lesser than traditional PBN or Key Systems, but also due to ease of installation. Today, VoIP is one of the most potential telephony solutions that has revolutionized business communication. Reaching out to clients and branch offices across the globe doesn’t quite concern the business enterprises; rather, the advanced features and budget friendly price considerably add to the triumph!
