For the UCM6510 IP PBX, the HA100 provides an automated failover solution. When two UCM6510s are connected, the HA100 continuously checks the operational status of both UCM6510s and, in the event that one fails, switches the system control to the hot-standby secondary UCM6510. This includes all connected telecom lines, network links, auxiliary devices, and all SIP endpoints that were previously registered on the primary UCM6510. Depending on the quantity of SIP endpoints registered, it can complete the entire system switch in between 10 and 50 seconds. The HA100 is a perfect high-availability solution for the UCM6510 to guarantee maximum total system reliability and uptime because of its intelligent monitoring and automated failover capability.
