VoIP: how it started and why it matters more than ever
VoIP grew out of experimental internet calling in the 1990s and is now the backbone of modern business communication, especially for Belgian SMEs. As remote work, cloud software, and AI have become the norm, VoIP is more relevant than ever for businesses that want to call smarter, more flexibly, and in a more customer-focused way.
From noisy modem to crystal-clear VoIP
In the 1990s, pioneers like VocalTec took the first steps in internet telephony, allowing calls over the internet through a computer and a slow connection. Quality was limited, but the promise was clear: conversations no longer had to travel over copper lines.
Around 2000, broadband internet and better codecs drove a breakthrough, with services like Skype bringing VoIP to the mainstream and sharply reducing the cost of international calls. At the same time, telecom providers began rolling out VoIP commercially as an alternative to traditional business telephony.
Why VoIP is the standard today
VoIP sends voice over the internet, making telephony far more flexible, scalable, and cost-efficient than traditional PBX systems in the basement. Businesses can add or move numbers, devices, and users without an on-site technician, which is ideal for growing SMEs.
Cloud-based VoIP and UCaaS solutions combine calling, video, chat, and integrations with tools such as CRM, giving sales, support, and management more insight into customer interactions and performance. This aligns perfectly with digitalization in Europe, where virtual telephony and IP telephony continue to grow year after year.
Remote, hybrid, and always on
Since remote and hybrid work became mainstream, fixed-line telephony is no longer enough to connect teams and customers smoothly. VoIP makes it possible to call with the same business number via laptop, smartphone, or softphone, from home, the office, or on the go.
For SMEs, this means telephony is no longer tied to one location, but to the team and its processes. You switch seamlessly between colleagues, offices, and even countries, without expensive infrastructure or complex hardware.
From calling to smart conversations with AI
The next evolution is that VoIP not only carries conversations, but also understands and enriches them with AI. Think of automatic transcriptions, per-call summaries, and virtual assistants that welcome customers, route calls, and answer simple questions.
Fonzer positions itself as a telephony platform that excels in AI applications on top of powerful VoIP functionality. This helps businesses not only call more efficiently, but also extract more value from every customer interaction. It gives SMEs a competitive edge: they respond faster, smarter, and more consistently, without adding pressure to their teams.
Why now is the time to switch
The market for VoIP and virtual telephony is growing strongly, with forecasts pointing to double-digit growth toward 2030 driven by cloud and remote work. At the same time, traditional telephony solutions are increasingly being phased out, making migration to VoIP not just an opportunity, but a necessity.
For Belgian SMEs, this is the moment to modernize telephony: lower costs, more flexibility, and room to deploy AI features like transcriptions, summaries, and virtual assistants intelligently with a platform like Fonzer. In the next blog in this series, we will take a deeper look at how to switch to VoIP step by step without risking availability or customer experience.
