VoIP technology has been around for several decades, with its beginnings dating back to the 1970s. However, it started to gain traction in the 1990s. Here are some of the key historical developments in the VoIP domain.\u00a0<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Introduction of the First VoIP Application in 1995:<\/b><span style=\"font-weight: 400;\"> This VoIP app was launched by VocalTec Communications and was named \u201cInternet Phone\u201d. It was the first time that users were able to make voice calls over the Internet.\u00a0\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Introduction of H.323 Standard in 1996:<\/b><span style=\"font-weight: 400;\"> The ITU-T i.e. International Telecommunication Union (ITU)\u00a0 introduced this standard. Its role was to provide a framework for multimedia communication over IP networks and establish interoperability among different VoIP systems.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Adoption of Broadband Connections in the Late 1990s:<\/b><span style=\"font-weight: 400;\"> The proliferation of broadband Internet connections improved the quality and reliability of VoIP calls, making them more attractive to consumers and businesses.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>The Launch of Skype App in 2003: <\/b><span style=\"font-weight: 400;\">This app offered a user-friendly interface and peer-to-peer technology.\u00a0 It became a major player in the VoIP market, making international calls affordable and convenient.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Rise of Session Initiation Protocol in 2000s<\/b><span style=\"font-weight: 400;\">: SIP gained popularity as a signaling protocol, making it easier to set up and manage VoIP calls, and paving the way for the interoperability of VoIP systems.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Adoption of VoIP in Business in the 2000s:<\/b><span style=\"font-weight: 400;\"> VoIP began to be widely adopted in the business world, leading to the development of business-oriented VoIP solutions and IP PBX systems.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Transition to Cloud-Based VoIP in the 2010s:<\/b><span style=\"font-weight: 400;\"> Cloud-based VoIP solutions became prevalent, offering scalability and flexibility for businesses.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">Ever since, VoIP has continued to evolve with the development of new codecs, improved call quality, enhanced security, and the integration of artificial intelligence for various applications.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Types_of_VoIP_Systems\"><\/span>Types of VoIP Systems<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-4068 aligncenter\" src=\"https:\/\/www.revesoft.com\/blog\/wp-content\/uploads\/2023\/11\/voip-usage-by-deployment.jpg\" alt=\"voip usage by deployment\" width=\"700\" height=\"540\" \/><\/p>\n<p><span style=\"font-weight: 400;\">VoIP systems can be categorized into two main types: On-premise and Cloud-based VoIP systems. Understanding these types is essential if you are considering the implementation of VoIP in your business.\u00a0<\/span><\/p>\n<h3><span class=\"ez-toc-section\" id=\"On-Premise_VoIP\"><\/span>On-Premise VoIP<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p><span style=\"font-weight: 400;\">This type of VoIP setup is done within your own premises. It offers complete control and customization. However, a huge upfront investment is required for on-premise setup. Due to this, it is an ideal option for large organizations with sufficient financial and IT resources.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Now, you must have one question in mind. What are the startup requirements? What equipment do you need if you want to switch your business telephone service to on-premise VoIP?\u00a0<\/span><\/p>\n<h4><span class=\"ez-toc-section\" id=\"What_is_the_Equipment_Needed_for_On-premise_VoIP_Setup\"><\/span>What is the Equipment Needed for On-premise VoIP Setup?<span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><span style=\"font-weight: 400;\">This type of setup needs extensive hardware and additional infrastructure, including:<\/span><\/p>\n<ul>\n<li><b>Analog Telephone Adaptors: <\/b><span style=\"font-weight: 400;\">Also called ATAs, these are the devices that connect traditional analog phones to the VoIP network so that communication can happen over the internet.<\/span><\/li>\n<li><b>VoIP Server or PBX (Private Branch Exchange):<\/b><span style=\"font-weight: 400;\"> It is the private phone network used within a company. It manages internal communication within the company as well as external incoming and outgoing calls.

You just need to install any of these programs on your PC to call any landline or mobile phone. One popular example is GoogleTalk. If the recipient also has the app installed, then usually the call is free of cost. However, calling a regular phone number will incur some call charges.\u00a0<\/span><\/li>\n<li aria-level=\"1\"><b>Smartphone\/ Tablet: <\/b><span style=\"font-weight: 400;\">There are many VoIP apps through which you can do VoIP calling using your smartphone or tablet. Some popular examples are WhatsApp and Viber.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>IP Phones:<\/b><span style=\"font-weight: 400;\"> These are specialized phone devices designed for VoIP calls. The look and function of IP phones are almost similar to traditional phones. However, they work by connecting to the internet instead of landline.\u00a0<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"How_Does_VoIP_Work\"><\/span>How Does VoIP Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Now, let\u2019s give you a<\/span><i><span style=\"font-weight: 400;\"> behind-the-scenes<\/span><\/i><span style=\"font-weight: 400;\"> look! Here we are going to explain the working of VoIP technology in the simplest way possible. So, let\u2019s take a look:<\/span><\/p>\n<p><b>VoIP works on Packet Switched Technology\u00a0<\/b><\/p>\n<p><span style=\"font-weight: 400;\">Traditional telephony works on circuit-switching technology, which is no longer efficient and cost-effective. On the other hand, VoIP makes use of the Packet-Switching method. It works by creating a brief and instant connection every time the user speaks. The connection does not need to go on both ends all the time. Moreover, data packets are sent in little pieces instead of all at once. It\u2019s more efficient because different data packets can use different routes and still reach their destination and reassemble.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While VoIP may sound technical or complicated, the way data transmission happens during a VoIP call is quite simple to understand. Here\u2019s how it happens:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Voice of the user or audio signal is converted into digital data by using the process of digitization.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Digital data is often compressed to make it more efficient for transmission over the network. This compression is done using Codecs.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Compressed voice data is then broken down into small pieces called packets. Each Packet has its header that includes source, destination, and sequencing information.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Packets are transmitted over the network using the packet-switching method. They take different routes to reach their destination.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">At the receiving end, the packets are reordered, depacketized, and decompressed using the same codecs.\u00a0<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">This digital data is converted back into an analog signal which is played back through the recipient\u2019s device. The message is heard by the recipient.\u00a0<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">In short, when you make a phone call, VoIP converts your voice into digital signals. These signals are then compressed and sent to the other end via the internet. On the receiving end, the digital signals are uncompressed and the recipient hears the sound.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Since VoIP works over the internet, the data is stored on a relatively secure cloud. To manage your VoIP system, you need to access your online dashboard where you can adjust contacts, and phone numbers and make additional settings.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">By now you must be curious to know the practical usage of VoIP. Let\u2019s explain.\u00a0<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Main_Uses_of_VoIP_Technology\"><\/span>3 Main Uses of VoIP Technology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">VoIP offers a wide range of uses in modern communications.
