VOIP, or Voice over Internet Protocol (also referred to as IP telephony) is a technology that uses internet protocol (IP) networks to transmit voice and multimedia content via the internet. Whilst traditional phone systems rely on circuit-switched networks, VOIP converts voice signals into compressed digital data packets, transmitting them over IP networks for cost-effective, almost consistent and instantly accessible communication. Popular VOIP applications include Skype, WhatsApp, Viber, Google Chat, Google Meet, Facetime, Facebook Messenger, and Telegram, amongst many others. This technology not only enables voice calls but also offers advanced features such as video calls, voicemail, instant messaging, team chats, and email. Users can make calls from various devices, including computers, smartphones, and dedicated VOIP phones. A VOIP phone system is designed to transfer voice traffic exclusively via the internet connection. IP technology can transfer voice, fax, messaging and other data traffic. VOIP systems often come with an array of other advanced features such as call forwarding, voicemail-to-email, and video conferencing, and offer smooth integration with other digital tools such as customer relationship management (CRM) systems and virtual reality (VR) applications.
VOIP calls can be made from any area that offers internet access, while landline calls may be limited to specific geographic areas, such as in countries such as South Africa where there can be an either/or situation. Although VOIP allows calls to and from landlines, this facility often comes with additional costs. Essentially, VOIP facilitates voice communication and multimedia sessions via the internet, offering a versatile and cost-effective alternative to traditional phone systems, making it significantly more convenient.
However, VOIP requires a reliable and stable internet connection as connectivity issues can arise from factors like faulty or outdated modems, network congestion, internet service provider (ISP) outages, and physical distance from the router. Other issues may include cable connection problems, signal interference, adverse weather conditions, domain name system (DNS) issues, and IP address conflicts. The majority of internet cables are located in the ocean, running along the seafloor as "undersea cables" or "submarine cables", which are essentially fibre optic cables that carry over 95% of global internet traffic between continents. Although they are buried deep in the ocean floor, cables can be damaged by fishing nets, anchors, or natural disasters, posing continuous potential threats to instant global communication.
