HAPBX combines a powerful feature set with a user-friendly interface, allowing you to easily manage your entire communications system with guaranteed 99.99% uptime.
Launch and scale your business with an enterprise-grade communication platform without the enterprise-level costs. Our SaaS model means you pay only for what you use, turning your communication expenditure from a capital burden (CapEx) into a predictable operating expense (OpEx).
Empower your distributed workforce and unify global communications on a single, secure platform. Integrate seamlessly with your existing tech stack (CRM, Helpdesk) to unlock new levels of productivity and customer intelligence.
Reduce your Total Cost of Ownership (TCO) by eliminating hardware maintenance, manual updates, and on-site support. Our SaaS platform provides superior reliability, security, and analytics, ensuring a measurable return on your investment.
For your business, a dropped call isn’t just an inconvenience, it’s lost revenue and a damaged reputation. That’s why our platform isn’t merely “hosted in the cloud”
It’s built upon an enterprise-grade, fully redundant High Availability (HA) cluster, meticulously designed to eliminate single points of failure. We manage the complexity, so you experience uninterrupted continuity
Your entire PBX environment runs on a primary, active server. Simultaneously, a complete, identical standby server is running in parallel, ready to take over in an instant. This isn’t a cold backup; it’s a live, mirror image
Every call record, every configuration change, every voicemail—every single piece of data—is replicated from the active to the standby server in real-time at the block level. We use DRBD (Distributed Replicated Block Device), the industry standard for high-performance data mirroring, ensuring zero data loss during a failover.
The cluster’s health is constantly monitored by Pacemaker & Corosync, an enterprise-grade cluster management stack. They act as the system’s “brain,” sending “heartbeat” checks every second. If a heartbeat is missed from the active server—due to hardware failure, network issues, or software glitches—the cluster instantly and automatically triggers a failover.
All your phones and SIP trunks connect to a single, virtual “Floating IP,” not the physical IP of a server. During a failover, this Floating IP is instantly reassigned to the standby server, which then becomes the new active server. For your end-users and customers, the transition is seamless and virtually undetectable.
