All about the First VoIP Phone
Voice over Internet Protocol (VoIP) is a technology that utilizes the Internet to make voice calls, carry out video conferencing, and other communication processes. The development and growth of VoIP technology has resulted in clear, efficient, and secure communication. Organizations that switch to VoIP enjoy simplified communication, reduced costs, and increased productivity. Where did it all start? Let’s delve into the first VoIP phone that gave rise to the VoIP systems that we use today.
The first VoIP phone was created in 1995 by VocalTec, an Israeli telecommunications equipment company. The VocalTec innovation involved converting an analog sound signal into a digital signal transmitted over the Internet. VocalTec named this system “Internet Phone,” and it became the first-ever VoIP phone worldwide. The Internet Phone transferred voice signals over the Internet using Real-Time Transport Protocol (RTP) and Session Initiation Protocol (SIP), signaling the protocol responsible for setting up and tearing down multimedia communication sessions. At the base of the Internet Phone was the “Audio Transceiver,” which managed the dynamic jitter buffer critical for achieving adaptive lower possible audio latency along with handling packet loss, packet re-ordering, and receiver transmitter sample rate adjustments.
The Internet Phone launched in 1995 and became an online sensation, attracting millions of users worldwide. The Internet Phone paved the way for other companies to develop similar solutions, taking advantage of the growing Internet connectivity and the increasing demand for more mobile communication.
The original Internet Phone was not what it is today. For example, VocalTec charged registration and per-minute fees–and subjected users to advertisements before calls–but this still saved customers money on international and long-distance calling rates.
Low bandwidth speeds meant poor audio quality, frequently dropped calls, and severe latency and packet loss. These problems prevented VoIP technology from becoming an overnight success. In its infancy, VoIP calls made up just 1% of all phone calls.
This first VoIP phone was revolutionary because it influenced a significant paradigm shift in how communication was conducted, paving the way for the development of other services such as instant messaging, video conferencing, and social networking. Advancements in VoIP technology have brought more than a tremendous shift in the business world, as it has impacted every facet of life-complicating communication, making it convenient and straightforward.
