What are VoIP solutions?

VoIP stands for Voice over Internet Protocol. VoIP solutions send your voice calls across an IP network instead of traditional phone lines. Your phone turns each word into small digital packets; the packets travel across your internet connection, and the person you called hears you in real time.

Because a VoIP call uses your existing broadband connection, you can replace traditional phone lines without rewiring your office. Fibre, LTE and fixed wireless all work. Your team then takes voice calls on a desk phone, a laptop or a smartphone, all on one business number.

A VoIP system also brings advanced features such as call forwarding, voicemail to email, video conferencing, call analytics and more into one platform that you manage online.

Contact us to find the VoIP solution that matches how your team works.

Why South African businesses switch to VoIP

Traditional phone lines come with costs and limits many South African businesses have outgrown. Line rentals and per-minute charges push your phone bill up, ageing equipment needs expensive maintenance, and adding staff or moving offices means waiting for technicians and new cabling. When the power or the line fails, your customers cannot reach you.

VoIP solves these pain points by carrying your voice calls over your existing internet connection. You pay less, adapt faster and stay reachable wherever your team works. Explore the benefits below and contact us to find the VoIP solution that fits your team.

Frequently Asked Questions About VoIP Solutions for Businesses in South Africa

Prices depend on the solution, the number of users and your call volume. A basic virtual landline costs the least, and a full cloud PBX with advanced features costs more. Hardware, contract length and calling patterns also change your VoIP cost.

Our virtual landlines start at R135 per month, cloud PBX extensions at R65 per month and unlimited calling at R350 per user per month, all excluding VAT. We list what each package includes, so you know what you pay before you sign.

Contact us for a quote based on your team size and call volume.

Not always. VoIP runs on your existing internet connection as long as it is stable and has enough bandwidth for the number of calls you make at once. Fibre and LTE both work well.

We check your connection before you switch and tell you if an upgrade would improve call quality. If you need a new line, our bundled fibre and LTE packages give you internet and phone service from one supplier.

Wondering if your connection can cope? Ask our team to test it before you commit.

VoIP needs power for your router and any desk phones, so an outage can affect calls. With the right setup, you keep working. A battery backup on your router and a mobile app on a charged smartphone keep your lines open.

Our services include redundancies for power outages, and you can reroute your business number to a smartphone through our self-service portal in minutes. Your team keeps answering calls even when the office goes dark.

Protect your phone lines from power cuts. Contact our specialist to find out which backup options suit your office.

A cloud PBX is a complete phone system that a provider hosts for you, so you need no on-site switchboard. SIP trunking connects a PBX you already own to a VoIP network, replacing your copper lines while you keep your handsets.

We supply both, and our consultants recommend the one that fits your equipment and budget. Many customers start with SIP trunking and move to United Voice Cloud when their PBX reaches the end of its life.

Contact us to compare both options with one of our specialists. Share your current setup, and we will recommend a suitable path.
