High-speed internet connectivity is an absolute necessity for modern companies, not only for their cloud-based services but also for their communications. Video conferencing and voice telephony systems, known as voice over internet protocol (VoIP), revolve around reliable fibre connectivity.

Despite this, one-quarter of South Africans still do not have access to internet connectivity at all. Fibre connections use tiny glass strands to transmit data as pulses of light, which means faster speeds, lower latency and better reliability. Fibre networks are expanding rapidly in South Africa; most major cities are fully covered but remote areas are now the focus for infrastructure providers.

As an ICT services provider, SEACOM understands the importance of fibre in transforming business communications. We have a far-reaching network of fibre infrastructure that forms the basis of many of our services, including VoIP communications – a robust and reliable telephony system that can transform your internal and external communications.

What is VoIP?

VoIP allows voice communication over the internet, offering numerous benefits to companies over traditional telephony. It enables businesses to make calls using their internet connection, eliminating the need for dedicated telephone lines. VoIP offers cost savings, flexibility, scalability and advanced features, making it a preferred choice for modern companies.

However, the success of VoIP depends heavily on a reliable and stable internet connection, and this is where high-speed fibre becomes essential. A reliable high-speed internet connection is able to transmit voice data packets in real time. Fibre's fast speeds provide the necessary bandwidth for crystal-clear voice calls without delays or interruptions.

Bandwidth is important when it comes to VoIP calls, especially those involving video conferencing or large file transfers. Fibre connectivity caters to the bandwidth-intensive nature of VoIP, enabling businesses to conduct simultaneous calls and data transmissions without compromising call quality.

What’s more, a stable and reliable internet connection improves the voice quality of VoIP calls. Unlike traditional telephony that may suffer from signal degradation and interference, fibre provides consistent audio clarity, minimising glitches and call drops. This ensures effective communication and delivers a professional experience to customers and clients.

What to consider when implementing VoIP

When implementing fibre and VoIP, businesses need to consider several factors, starting with infrastructure. Companies must have the necessary infrastructure in place to support fibre connectivity and VoIP. This includes installing fibre optic cables, network switches, routers, and IP-enabled phones. It may require collaboration with an experienced ICT services provider like SEACOM to ensure seamless integration.

Next, IT systems may need an upgrade. Integrating VoIP into existing IT systems is essential for a smooth transition. Companies need to ensure compatibility with their network infrastructure, firewalls and security protocols to safeguard their communication and data.

There are always cost considerations too. Implementation costs for fibre and VoIP vary depending on the size and complexity of the business. It includes equipment costs, installation fees and subscription fees for VoIP service providers and internet service providers (ISPs). However, the long-term cost savings and operational efficiency gained from VoIP often outweigh the initial investment.
