The History of VoIP Technology

Voice over Internet Protocol, also referred to as VoIP, is a technology that has taken the business world by storm. The use of the Internet has delivered with it a large amount of innovation related to communication. Email was one of the first innovations to be introduced and then communicating in real time brought about the introduction of instant messaging. Still, others wished for a more personal connection, and this is where the history of VoIP technology comes in.

What is VoIP Technology?

To put it in the most basic of terms, VoIP represents the transmission of voice “data packets” from one IP address to another IP address through the Internet. The history of VoIP begins around 1995, when it originally served as a way to work around long-distance and international telephone call charges. With just over two decades under its belt, VoIP has essentially revolutionized communication worldwide.

VoIP may not seem like that big of a deal at first glance, especially when most people have access to cell phones these days, but VoIP is actually extremely useful and important.

How Does VoIP Work?

VoIP works by transferring voice signals from one IP address to another, which means that these voice signals must first be transformed into pieces of data that are small enough to be able to transmit. Voice samples from the sender are broken down into “data packets,” which are then given routing information and then sent to the receiving party. The packets are then transmitted one at a time and reshaped together as close to their original state as possible, which creates one whole voice. This process first compresses the voice signal and then decompresses the voice signal for the receiver.

The Origins of VoIP: Taking it Back to 1995

VoIP technology would not exist today if it were not for three critical inventions, which are the telephone, the Internet, and Internet Protocol. Internet Protocol was the last of the three to be invented and it essentially defines how information is able to travel between computers.

The history of VoIP technology began in 1995. A company called VocalTec pioneered the first widely available Internet telephone, which was called InternetPhone. It allowed an Internet user to call another Internet user. It was a voice call, with no video availability. In 1998, VocalTec created computer-to-telephone and telephone-to-telephone calling abilities for VoIP. There was some redundancy and other developments began. During the following year, telephone equipment manufacturers and telecommunications specialists started to use these newly developed digital transmissions to their benefit. This manner of transferring information via IP-focused packages was attractive because of the speed of transmittal, the overall high quality, and the lower cost involved.

The developments in the history of VoIP technology forged forward and eventually, VoIP switching software was introduced as standard add-on features for routing equipment. Communications hardware manufacturers were hard at work producing equipment for VoIP calling that could switch smoothly. Consumers began to increasingly recognize the benefits of VoIP calling. Companies that had offices around the world also began to note the advantages of utilizing this technology in their communications.

As the popularity of the Internet grew and the knowledge of benefits offered by VoIP also grew, many companies turned to VoIP to help move their call centers overseas. Over the years, advances in technology helped to offer several ways for a person to communicate with another using VoIP, including:

  • PC to PC
  • PC to Phone
  • Phone to Phone
  • IP Phone to Phone
  • IP Phone to IP Phone

Session Invitation Protocol, also referred to as SIP, was also developed in the early 2000s and has since been widely used for instant messaging and chat groups, group conferencing, and much more.

This short summary of the history of VoIP technology brings us to today, where a plethora of technological advancements have helped to make VoIP an integral part of the everyday lives of many people worldwide. Many use the technologies to stay in touch with family at a low cost, while others use it within their companies as an efficient and cost-effective way to support their communications. The future of VoIP technology is bright as it offers a simplification of communication processes and a flexibility that is unparalleled.
