Link-Up ICT — cloud PBX and business voice provider in Johannesburg
Link-Up ICT & Cyber Security operates from Northlands Corner in Northriding, Johannesburg, and sells business voice as part of a managed ICT and security offering. Voice appears in two forms on the site, an IP PBX and voice over Microsoft Teams, sitting alongside managed IT, cloud, Microsoft 365, hardware and managed document solutions. Its Google profile carries 4.8 from sixteen reviewers, and published support hours run 08:00 to 16:30 on weekdays.
Key facts
| Who they are | A Johannesburg managed ICT and cyber security company selling business voice within a wider technology relationship rather than as a standalone telephony product |
| Voice services | IP PBX and voice over Microsoft Teams, grouped on the site under data and voice. The two are different buys, so establish which is proposed |
| Also offers | Managed IT services, cyber security, cloud solutions, Microsoft 365, hardware and infrastructure, and managed document solutions |
| Head office | 1st Floor, Block A, Northlands Corner, corner Witkoppen and New Market Roads, Northriding, Johannesburg, 2162 |
| Coverage | Not published as a footprint. The company is Johannesburg based and the managed-services model implies on-site work within reasonable reach |
| ICASA licence | No ICASA reference is published. For an IP PBX or Teams calling provider the ECS licence normally sits with the underlying trunk supplier |
| Pricing | Quote-based. Nothing is published, which is normal for a managed ICT agreement priced across several service lines |
| Support hours | Published as 08:00 to 16:30 Monday to Friday. That is standard business hours rather than 24/7, which is worth confirming if your operation runs outside them |
| Listed In | Cloud PBX Providers |
Check the support hours before the feature list
Link-Up publishes its support hours as 08:00 to 16:30 on weekdays, which is more useful information than most providers volunteer and deserves a moment of thought. If your business is a weekday office, that is a perfect match. If you run a retail operation, a warehouse on late shifts or anything trading at weekends, a phone fault on a Saturday sits outside those hours and you need to know what happens then before you sign. On the product itself, the site names both an IP PBX and Teams voice, and those are genuinely different purchases with different lock-in profiles, so ask which one is proposed. The wider security and managed-IT line, including a named cyber security practice, suits a business consolidating suppliers. Compare voice specialists in the cloud PBX directory.
Who Link-Up ICT is a fit for
- Weekday Johannesburg offices wanting phones inside a managed ICT contract
- Businesses adding calling to an existing Microsoft 365 environment
- Companies that want cyber security and telephony from one supplier

Does Link-Up offer an IP PBX or Teams calling?
The site names both. They are different purchases: an IP PBX is a phone system in its own right, while Teams voice puts calling inside your existing Microsoft environment. Ask which is being proposed and how easily you could change later.
What are the support hours?
Published as 08:00 to 16:30 Monday to Friday. That is standard business hours rather than round-the-clock cover, so confirm the arrangement for evenings and weekends if your operation trades outside them.
Where is Link-Up based?
1st Floor, Block A, Northlands Corner, on the corner of Witkoppen and New Market Roads in Northriding, Johannesburg.
Does Link-Up handle cyber security as well?
Yes, and it is named in the company’s trading name rather than buried in a service list. Cyber security sits alongside managed IT, cloud and Microsoft 365, which suits a business consolidating technology suppliers.
What does it cost?
No pricing is published. Managed ICT agreements bundle several service lines, so ask for the telephony charge itemised separately along with per-minute call rates and any handset or licence costs.
How long has Link-Up been trading?
No founding year is published on the site, so WhichVoIP does not state one. Ask for company registration details if trading history matters to your evaluation.
