The HA100 is a Grandstream controller for the UCM6510, which offers an automated failover solution. It's ideal for any business that requires an always-on, redundant voice system by providing an automatic failover when paired with 2 UCM6510 IP PBXs. The HA100 constantly monitors the operational status of both UCM6510s and will automatically switch all system controls over to the secondary UCM6510 when the primary device fails for any reason.
