Why cloud instead of your own hardware
No upfront investment
No server to buy. You pay a monthly fee — an operating expense instead of a capital one.
We handle maintenance and updates
Security patches, new features, monitoring — all included in the service. You focus on your business.
No hardware failure risk
When a disk or power supply fails in your office, you keep calling. Your PBX runs in a professional datacenter with redundancy.
Scale by changing plans
Growing? Move to a higher plan. Downsizing? Switch back. No surplus hardware.
