Cloud PBX • Market shift

The PBX vendors South Africa has lost, and what it means if you still run one

Panasonic, Samsung, Toshiba and NEC’s on-premise lines have all exited or ended support, and no new maker has stepped in. If your business still runs one of these systems, the clock on parts and support is already running. Here is the honest picture, and the way out.

The short answer

Which PBX vendors have left the market, and should I be worried?

Several long-standing on-premise PBX makers have exited or ended support: Panasonic, Samsung and Toshiba have left business telephony entirely, and NEC has wound down its on-premise systems. No new manufacturer has replaced them; the industry moved to cloud instead. If your business runs one of these systems it still works, but it is now unsupported or nearly so, with shrinking spare parts. That is not a reason to panic, but it is a clear signal to plan a migration before a failure forces your hand.

Why the PBX makers walked away

This was not one company’s bad luck. It was a whole product category losing its reason to exist, for three connected reasons.

First, cloud communication caught up with what businesses actually want: softphones, mobile apps, browser calling and tight links to tools like CRM. Traditional PBXs were never designed for that, and bolting it on was expensive. Second, building the hardware stopped paying. Global demand fell, manufacturing costs rose, and the makers shifted their money to software and cloud platforms. Third, and most decisive in South Africa, the line technologies that on-premise PBXs depend on, copper, ISDN and analogue trunks, are being retired. Take away the lines and the box on the wall loses its purpose.

End-of-support timeline for the major exits

The vendors we’ve lost

Each of these names is still humming away in South African offices, hotels and clinics. Here is where each maker stands, and what it means if you depend on one.

Panasonic

Announced its exit from business communications in December 2020, ending new PBX and SIP system supply.
Affected ranges include the KX-NS, KX-TDE and KX-NCP families still widespread here.
What it means: no new hardware or feature updates, shrinking genuine spare parts, growing reliance on refurbished units.

Samsung

Ended manufacturing and support of its OfficeServ and SCM platforms, with all Samsung support stopping at the end of 2021.
Common in hospitality and corporate offices, where many units are still in daily use.
What it means: no software updates, closed vendor support channels, hardware failures needing third-party help.

NEC (on-premise)

Withdrew from on-premise systems. For the UNIVERGE SV9100 and SL2100, new sales ended in December 2024 and NEC technical support ended on 31 March 2026.
NEC continues as a brand, but its focus has moved away from on-site PBX hardware.
What it means: these systems now run without manufacturer patches or security updates; transition planning is overdue, not optional.

Toshiba

Wound down its telecommunications division in 2017, with the business moving to Mitel.
Strata CIX and IPedge systems reached end of technical support in October 2021.
What it means: a fully orphaned platform, maintained only through third parties and dwindling parts.

What businesses are adopting instead

The replacement for an on-premise PBX is not a newer box. It is a different model entirely, hosted in the cloud and delivered as a service.

Modern South African telephony runs on cloud PBX and UCaaS platforms, where calling, messaging and meetings live in one place and scale with a few clicks. SIP trunking carries voice over the same data connection that runs the rest of the business, replacing the copper and ISDN lines being switched off. Collaboration-integrated calling puts the phone inside the tools teams already use, and AI layers, transcription, automated routing, analytics and virtual agents, sit on top to do work the old PBX never could. The thread running through all of it is that nothing depends on a single ageing cabinet whose maker has left.

Factor	Cloud PBX / UCaaS	Legacy on-premise PBX
Vendor support	Actively developed and supported	Ended or ending; parts declining
Scaling	Add or remove users in a portal	New cards and physical installs
Remote work	Softphone and mobile from anywhere	Tied to the office wiring
Line technology	Rides on internet / SIP	Needs copper or ISDN being retired
Upgrade path	Continuous, included updates	Frozen at last supported version

How to migrate off a legacy PBX, without the drama

You do not have to rip everything out overnight. A planned, phased move keeps the business running and avoids paying twice.

Audit what you actually runDocument the make and model, how many extensions and trunks, what line types feed it, and which features staff genuinely use. This is the brief every provider will need to quote accurately.

Check your line and internet dependenciesFind out whether you are still on copper, ISDN or analogue trunks, and whether your internet connection can carry your call volume cleanly. The connection becomes the foundation once the PBX is gone.

Choose a cloud PBX or SIP pathDecide between a full cloud PBX, or SIP trunking into a kept-for-now system as a stepping stone. Match the choice to your size, your remote-work needs and your appetite for change.

Port your numbers firstYour business number is your identity. Confirm the porting process and lead time, and move the numbers onto the new platform before you switch anything off, so the business never goes silent.

Cut over in phasesMove a team or a site first, prove it works, then roll forward. Keep the old system live just long enough to fall back on, and retire it only once the new platform is carrying the load.

Bottom line: the risk is not the migration, it is waiting for a hardware failure to force one on a system nobody supports any more. Plan it while you still have a working fallback, and the move is calm rather than a crisis.

No new PBX maker is coming to rescue the box on your wall. The market did not pause; it moved to the cloud and left the hardware behind.

Our verdict

The exit of Panasonic, Samsung, Toshiba and NEC’s on-premise line is not a temporary gap waiting to be filled; it is the market telling you where business telephony has gone. If you still run one of these systems, it has served you well, but it is now living on borrowed time, unsupported and dependent on line technologies that are themselves being switched off. The good news is that the replacement is better in almost every way that matters to a growing business: supported, scalable, mobile and far less dependent on ageing hardware. The only real mistake is waiting for the system to fail before you act.

Our recommendation: if you run a Panasonic, Samsung, Toshiba or NEC on-premise PBX, start the migration conversation now, while the old system still works as a fallback. Audit what you have, port your numbers first, and move in phases.

Frequently asked questions

Which PBX vendors have exited the market?

Panasonic, Samsung and Toshiba have left business telephony entirely, and NEC has withdrawn from its on-premise systems. Panasonic announced its exit in 2020, Samsung and Toshiba ended support in 2021, and NEC technical support for the SV9100 and SL2100 ended on 31 March 2026. No new on-premise PBX manufacturer has replaced them.

My PBX still works, so why should I replace it?

It works until it does not. With the maker gone, there are no security updates or new features, spare parts are drying up, and a single hardware failure can leave you without phones and without a supplier to call. Migrating while the system still runs gives you a fallback and removes the crisis.

What happens when copper and ISDN lines are switched off?

On-premise PBXs that rely on copper, ISDN or analogue trunks lose the connection they were built around. SIP trunking and cloud PBX replace those lines by carrying voice over your internet connection, which is why the line retirement is accelerating the move to cloud.

Can I keep my phone numbers when I migrate?

Yes. Numbers are ported to the new platform through the standard porting process. Confirm the lead time with your chosen provider and move the numbers across before switching off the old system, so the business is never without its main line.

What is replacing the traditional PBX?

Cloud PBX and UCaaS platforms, delivered as a service, with SIP trunking for connectivity, collaboration-integrated calling, and AI layers like transcription and automated routing. The common thread is that calling no longer depends on a single ageing box on your premises.

How long does a migration off a legacy PBX take?

It varies with size and complexity, but a phased move, audit, choose a platform, port numbers, cut over team by team, lets you keep working throughout. The planning matters more than the speed: a well-sequenced migration avoids downtime far more reliably than a rushed one.
