Business VoIP Phone Systems Cape Town

Business VoIP Phone Systems, Installed & Supported

Reliable business phone systems, professionally installed across Cape Town.

A traditional office phone system means expensive hardware, long contracts and a call to a technician every time something needs to change. Alpha Electronics designs, installs and supports cloud-hosted business phone systems (VoIP) for offices, estates and developments across Cape Town and the Western Cape — hosted switchboards, SIP trunk lines, number porting and the handsets or softphones to go with them, all from one accountable team.

We install what we sell. That means your phone system, your network and your internet connection are handled by the same team — no finger-pointing between a telecoms provider and whoever cabled your office.

What we install

Hosted switchboard (PBX) — cloud-based switchboard functionality (extensions, call routing, IVR menus, voicemail, ring groups) with no on-site hardware to maintain
SIP trunk lines — the VoIP line(s) that connect your system to the phone network
Number porting — keep your existing business number(s) when you move to VoIP
Desk phones, cordless handsets & softphones — hardware supply and setup, or use a browser/mobile softphone on what you already have
Call recording & IVR / auto-attendant — for training, compliance, or a professional after-hours greeting
Fax-to-email — retire the fax line without losing the number

Bring your costs down

Unlike a traditional PBX, a hosted system has no expensive hardware to buy or maintain, no lengthy maintenance contract, and internal transfers between extensions are free — wherever those extensions physically sit. Add or remove extensions as your business changes size, without a technician visit or a new contract.

Stay reachable, even when the power isn’t

Cape Town businesses know load-shedding and connectivity hiccups aren’t hypothetical. A hosted phone system can forward calls to a mobile, another extension, or voicemail automatically if your office loses power or internet — so a call to your business doesn’t just ring out. Because we also install the network and connectivity behind it, we build the failover plan into the installation from day one, not as an afterthought.

Built for your business, not just your phones

Because Alpha Electronics already designs and installs business WiFi, structured cabling and fibre connectivity, your phone system isn’t a separate project bolted onto an existing network — it’s installed with full knowledge of the cabling and connectivity it depends on. One team, one point of accountability, from the internet line to the handset on your desk.

Frequently asked questions

What is a hosted business phone system (VoIP)?

A hosted, cloud-based phone system that gives your business full switchboard functionality — extensions, call routing, voicemail, IVR menus — without a physical PBX device on-site. Calls travel over your internet connection instead of a traditional phone line.

Can I keep my existing business number?

Yes. We handle number porting so you keep the number your customers already know when you move to a hosted VoIP system.

Do I need to buy new phones?

Not necessarily. A hosted system works with most SIP-compatible desk phones and with browser or mobile softphones on devices you already have. We also supply and install new handsets if you need them.

What happens if there’s a power cut or the internet drops?

Calls can be set to automatically forward to a mobile number, another extension, or voicemail, so you don’t miss calls during an outage. We build this into the setup as part of the installation, alongside backup-power recommendations for your router and phones where needed.

How much does it cost?

It depends on scope — how many extensions and lines you need, whether you want a full hosted switchboard or just SIP trunk lines, and what handset hardware (if any) is required. We provide a free, on-site assessment and quote before any work begins, so pricing is exact to your business rather than a generic number.
