One platform, two ways to run it
Mezobyte has picked a lane and stayed in it. Everything voice-related here is 3CX, offered either as a hosted cloud PBX the company runs for you or as an onsite system on your own hardware, with VoIP trunks available either way. That choice is the useful one to think through. Hosted removes the server and the patching from your side and shifts call quality onto your internet line. Onsite keeps the PBX inside your building, which some buyers still want for a factory or a site with unreliable connectivity, and moves the maintenance back to you. Because the platform is the same in both cases, you can change your mind later without relearning the system. VoIPTools appearing alongside 3CX suggests the company builds beyond stock configuration, so ask what integrations it has actually deployed rather than what it lists. Nothing is priced publicly, so get the per-extension figure early. Compare the wider market in the cloud PBX provider directory.
Who Mezobyte is a fit for
- Alberton and southern Johannesburg businesses that specifically want 3CX
- Companies weighing a hosted PBX against keeping the system onsite
- Buyers who want the phone system and the IT support from the same supplier

What phone system does Mezobyte install?
3CX, in both hosted cloud and onsite forms, with VoIP trunking available on either. VoIPTools is named alongside it for extended functionality.
Where is Mezobyte based?
At Unit 5, Meyersdal Office Park, 65 Philip Engelbrecht Avenue in Alberton, Gauteng. The company also lists an office in Colorado in the United States.
When was Mezobyte founded?
No founding year is published. The site refers to more than 30 years of technical experience, which describes the team rather than the company, so this listing does not state a founding date.
Should I choose hosted or onsite 3CX?
Hosted moves the server and its upkeep to Mezobyte and makes your internet line the deciding factor in call quality. Onsite keeps the PBX in your building, which suits sites with unreliable connectivity, but the maintenance stays with you.
What does Mezobyte charge?
No pricing is published. Ask for the per-extension monthly cost, the trunk cost and any once-off setup separately.
Does Mezobyte supply internet as well?
Fibre internet is on the service list alongside managed IT, server hosting and backup, so the line can be quoted with the phone system.
