The HA100 offers an automated failover solution for the UCM6510 IP PBX. When connecting between two UCM6510 units, the HA100 constantly monitors the operational status of both devices and automatically switches the system control, including all connected telecom lines, network links, auxiliary devices, and all SIP endpoints previously registered on the primary UCM6510, to the hot-standby secondary UCM6510 in the event that the primary unit fails. It can complete the entire system switch in 10 to 50 seconds, depending on the number of registered SIP endpoints. Thanks to its smart monitoring and automated failover capability, the HA100 is an ideal high-availability solution for the UCM6510, ensuring maximum system reliability and uptime.
