What Is CallVault? The Complete Guide to Cloud PBX for SA Businesses

CallVault is ICTGlobe's enterprise-grade hosted cloud PBX (Private Branch Exchange) platform. In plain terms: it is your entire business phone system -- but hosted in ICTGlobe's data centres rather than in a box in your server room. Every call your business makes or receives, every extension, every voicemail and every conference bridge runs through CallVault's cloud infrastructure.

South African businesses have been slow to adopt cloud PBX compared to other markets, largely because of concerns about voice quality over local internet connections. CallVault was built specifically for the South African market -- engineered for ICTGlobe's own fibre and LTE network, which means voice quality is optimised end-to-end. Businesses using CallVault on ICTGlobe connectivity consistently report call quality that exceeds their old PSTN landlines.

The economics of CallVault are compelling. A traditional on-premise PBX for a 20-person office involves R80,000-R200,000 in hardware and installation costs, plus annual support contracts of R15,000-R40,000. CallVault replaces this entirely with a monthly per-extension subscription. There is no upfront hardware investment, no maintenance contract and no technology obsolescence -- ICTGlobe continuously updates the platform.

For businesses that have adopted hybrid or remote working, CallVault is transformational. The CallVault mobile softphone app means every staff member's smartphone becomes a full business extension -- receiving calls, transferring calls and accessing voicemail exactly as if they were sitting at their desk in the office. Your Cape Town team and your Johannesburg team work on the same phone system with seamless extension-to-extension dialling.

Migration to CallVault is simpler than most businesses expect. Number porting transfers all your existing numbers -- including 021, 011 and 086 numbers -- to CallVault without any interruption to inbound calls. Your customers call the same numbers. The change is completely invisible to them. Digitalx manages the entire migration process, typically completing within 5-7 business days.
