The HA100 is ideal for any business that requires an always-on, redundant voice system by providing an automatic failover solution when paired with two UCM6510 IP PBXs. The device will constantly monitor the operational status of both UCM6510s and will automatically switch all system control to the hot-standby secondary UCM6510 when the primary device fails for any reason.
