We all remember how back in the twentieth century to make any calls we would dial the operator and ask them to connect our call to the desired receiver. The process seemed a bit clumsy but had changed the communication mode as we know it today.
With the introduction of the internet, new ways of connecting with people also emerged. One of these was VoIP (Voice Over Internet Protocol).
Originally, it was designed by the Advanced Research Projects Agency Network (ARPANET), United States- Department of Defence for communicating across their operations in the year 1973. Gradually it has taken over a major share out of the telephone service provider companies’ revenue.
The Early 1900s
VoIP services transmit voice data packets over the internet, from one IP address to another. This period saw various developments. It was mostly used by the defense and other government departments as it offered better security at the time. Although the voice clarity was not optimum but compared to the available options at the time, was pretty decent. Most of the VoIP services relied on the advertisements and sponsorships to cover up the costs and lure customers. The leading critic of the field, ReviewVoip gives tells us more on how this scenario changed over the period.
It was this year that witnessed the first internet phone software developed by Vocaltec. Vocaltec converted compressed voice signals into digital packets and transmitted them over the internet. There were certain shortcomings to this, such as; both the users at either end had to have the same hardware and software. It used H.323 protocol instead of SIP protocol. Vocaltec was the first company to launch true VoIP.
1998- Early 2000s
The overall VoIP traffic in the US alone has grown to 1% of total voice traffic. New hardware and software were developed which enabled the subscribers to make computer to phone and phone to phone connections. Networking companies like Cisco, 3Com, and Lucent also introduced new network hardware that can now route and switch the VoIP traffic. As a result, the total VoIP traffic grew up to 3% of the total voice traffic in the US. It was until the US government broke these companies and reorganized the ownership rights to IP phones.
With the introduction of broadband Ethernet, the VoIP companies had gained a lot of popularity. Conventional calling was not used for calling out of the country or even across states. The VoIP service providers came up with calling plans as the conventional service providers. The plans varied from international calling plans to special flat rate plans for Canada, the European Union, and some Asian countries.
Current Scenario And Future Prospects
VoIP companies have evolved with time and improved the quality of service provided. It is preferred across various business and industry applications. VoIP in 2019 may see further advancements in protection against caller id spoofing, real-time communications, SIP trunking, IP phones, and Application programme interface.
With the introduction of IP based calling, the calling patterns have changed drastically over time. Businesses and corporate houses are benefiting most out of this. And with the integration of clouds, VoIP is to change our calling experience entirely.
