Altrix Systems — South African IP PBX manufacturer for business and hospitality
Altrix Systems builds its own phone system rather than reselling somebody else’s. Development started in 2008 and the company was formally established in 2009, working from Milnerton in Cape Town. The Altrix platform is a modular IP PBX scaling from a 48-extension appliance to a 10,000-extension enterprise server, with a hospitality edition that ties the phones into hotel check-in, guest billing and access control. It reaches buyers through install partners.
Key facts
| Who they are | A South African developer of converged communications systems. In its own words, “Altrix started in 2008 and was officially established in 2009. We started development on our Business PBX range and it grew from there.” It supplies PBX, telephony, intercom and access control into residential, SME, corporate and government environments |
| What they make | The Altrix PBX, an IP-based converged communications platform on a modular architecture that allows incremental expansion and remote upgrades. This is a product, not a service — the company builds and licenses the system rather than operating a network |
| Capacity ladder | Three published tiers. Lite handles 48 extensions and 16 concurrent SIP calls on an appliance chassis. Pro handles 1,000 extensions and 250 concurrent calls. Enterprise handles 10,000 extensions and 2,500 concurrent calls. Pro and Enterprise ship as 1U rack-mount servers with dual gigabit LAN ports; RAM runs from 8GB on Lite to 64GB on the largest Enterprise build |
| Technical detail | SIP, with audio codecs G711 (alaw and ulaw), G722, G726, GSM and G729, and DTMF support for in-band, RFC2833 and SIP INFO. Hardware redundancy and SIP phone auto-provisioning are listed. Published specifications at this level of detail are rare in this directory and make it straightforward to check the platform against handsets and trunks you already own |
| Hospitality edition | Altrix Hospitality integrates the phone system with hotel operations: a PMS interface, check-in and check-out, a guest room stock system, and call accounting with a billing engine so guest calls bill back to the room. Access control and intercom run on the same platform. Few phone systems in this market carry a hospitality feature set of this depth |
| Other editions | Multi-tenant for buildings housing several separate companies on one PBX, intercom and access control, hotspot, and a CRM client zone. Voicemail and voicemail-to-email, auto-attendant and music on hold are standard, alongside a Telephone Management System with reporting |
| How you buy it | Through an install partner, not from Altrix. The company states that “the Partner, in turn, installs and integrates the Altrix Systems into their client’s environment”, and that the relationship “is not mutually exclusive” on either side. So the party quoting, installing and supporting your system is the partner — ask how many Altrix sites they have commissioned and what happens if they stop carrying the product |
| Head office | Suite G09, Sable Square, corner Bosmansdam and Ratanga Road, Milnerton, Cape Town, 7441, Western Cape |
| Coverage | South Africa, delivered through the partner network rather than from branches. Installations referenced on the company site include Sandton and Eden Island |
| ICASA licence | An ECS or ECNS service licence does not apply to a manufacturer. The relevant compliance is ICASA type approval per device model, so confirm type approval for the specific Altrix appliance and handsets quoted to you |
| Pricing | Quote-based through an install partner. No price list is published, which is normal for a channel-sold platform — expect a hardware or licence cost plus a separate support and maintenance arrangement, and get both quoted separately |
| Customer rating | No rating is shown. An “Altrix Systems” Google Business Profile exists with a matching domain and the same Milnerton address, but it is unclaimed and carries no reviews, so there is no Google score to publish |

A locally built PBX, bought through somebody else
Almost every phone system sold in South Africa is designed elsewhere and imported. Altrix is one of the few developed here, and that changes two practical things. Escalation is the first: when a platform bug needs the vendor rather than the installer, the vendor is in Cape Town on your time zone rather than in Seoul or Taipei. The second is the feature set, which has clearly been shaped by what South African buyers actually ask for — a hospitality edition with PMS integration, check-in and check-out and guest call billing, a multi-tenant mode for buildings with several companies on one system, and intercom and access control on the same box. A hotel or an estate is not a mainstream target for most PBX vendors, and here it is a first-class product line. The published specification ladder deserves use rather than admiration. Read the concurrent-call figures, not the extension counts, because that is the number that decides whether the system copes at your busiest hour: 16 simultaneous calls on Lite, 250 on Pro. Then do the partner diligence, which is the substantive work. You buy from an install partner, the partnership is explicitly non-exclusive on both sides, and quality varies between installers in a way the product specification cannot tell you about. Ask how many Altrix systems the partner has commissioned, who answers after hours, and what happens to your support if that partner moves on. Compare service providers who own the whole delivery in the phone system directory.
Who Altrix Systems is a fit for
- Hotels and guest houses needing PMS integration, check-in and check-out and guest call billing
- Multi-tenant buildings and estates wanting phones, intercom and access control on one platform
- Organisations that want a locally developed system with escalation to a South African vendor

Size the system on concurrent calls rather than extension count, because that is what decides whether it holds up at your busiest hour. If you are a hotel or a multi-tenant building, say so early, since the hospitality and multi-tenant editions are the strongest part of this platform. Then ask which install partner would handle you, how many Altrix sites they have commissioned, and get the hardware and the ongoing support quoted as separate numbers.

Is Altrix Systems a phone company or a manufacturer?
A manufacturer. It develops the Altrix converged IP PBX in South Africa and licenses it through install partners rather than operating a network or selling airtime and minutes.
When was Altrix Systems founded?
Development started in 2008 and the company was officially established in 2009, according to its own About page.
How big a business can the Altrix PBX handle?
Three tiers are published: Lite at 48 extensions and 16 concurrent SIP calls, Pro at 1,000 extensions and 250 concurrent calls, and Enterprise at 10,000 extensions and 2,500 concurrent calls. Size on the concurrent-call figure rather than the extension count.
What makes the hospitality version different?
It integrates with a hotel property management system for check-in and check-out, runs a guest room stock system, and bills guest calls back to the room through a built-in call accounting and billing engine. Intercom and access control run on the same platform.
Can I buy an Altrix system directly?
Normally no. Altrix sells through install partners who install and integrate the system for the client, and it states the partner relationship is not mutually exclusive on either side. Ask which partner would handle your site and what they commit to.
Does Altrix need an ICASA licence?
Not an ECS or ECNS service licence, which applies to operators rather than manufacturers. The relevant compliance is ICASA type approval for each device model, so confirm it for the exact appliance and handsets in your quote.
