VOIP and Telecommunications Specialists: Impacting Digital Technology in Telecommunications
What is VOIP and How Does it Work?
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.
What is the Difference Between VOIP and Landlines?
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VOIP requires a reliable and stable internet connection as connectivity issues can arise from factors like faulty or outdated modems, network congestion, internet service provider (ISP) outages, and physical distance from the router.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.
The Role of Telecommunications Specialists
Telecommunications specialists are the designers and implementers who drive modern communication systems. A telecommunications specialist is a technical professional responsible for designing, installing, maintaining, and troubleshooting communication systems like phone lines, internet networks, and radio systems, ensuring seamless and efficient communication within an organisation by managing network infrastructure and resolving connectivity-related technical issues. These professionals ensure reliable connectivity, proactively troubleshoot issues and optimise network performance to ensure peak efficiency. As instant communication evolves and expands, their role is becoming increasingly essential for the smooth operation of modern connectivity demands.
Key Responsibilities of Telecommunications Specialists
The key responsibilities of telecommunications specialists include:
- Network installation and configuration: Setting up and configuring communication networks, including routers, switches, and security firewall devices that monitor and control incoming and outgoing network traffic. These devices act as security guards for a network, deciding what data can pass through and what cannot, based on pre-defined security protocols.
- Troubleshooting network issues: Diagnosing and resolving problems with network connectivity, data transmission, and overall system performance; diagnosing and resolving technical issues to minimise downtime; configuring VOIP systems to support diverse work environments, from traditional offices to remote setups, thereby enhancing global collaboration and remote work capabilities.
- System maintenance: Regularly monitoring network health, performing updates, and ensuring equipment functions properly. Regularly updating software and hardware to ensure compatibility and optimal performance, including AI-driven call analytics and unified communication. Their expertise is vital in designing, implementing, and maintaining the infrastructures that support VOIP and other telecommunications technologies.
- System upgrades and modifications: Implementing new technologies and updating existing systems to meet evolving and increasing communication needs. Ensuring high-quality service by minimising issues like latency (delay), inactivity, jitter, and packet loss. In networking, "jitter" refers to the inconsistency in the time between data packets arriving at their destination (arrival time fluctuations). In contrast "packet loss" means that some data packets fail to reach their destination entirely, getting lost during transmission. Packet loss represents the percentage of packets that don't reach their destination. This can be caused by network congestion, poor signal strength, or faulty network equipment, which often results in glitches, freezing, or interrupted data streams. Jitter can result in problems such as choppy video or audio playback, especially in real-time applications like video calls. High jitter can sometimes lead to packet loss if the system can't handle the irregular arrival times.
- Security management: Implementing and maintaining network security measures to protect against unauthorised access and cyber threats.
- Technical support: Assisting users regarding network access, troubleshooting issues, and answering technical questions.
In summary, telecommunications specialists are essential in ensuring that VOIP and telecommunications technologies function effectively, allowing seamless and efficient communication in today’s speed-driven world.
