Product description

Grandstream HA100 Automated Failover Solution

The Grandstream HA100 device offers companies an automated failover solution for the UCM6510 IP PBX system. 

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.

Fast and Reliable

The HA100 can switch entire system functionality (including all of the connected telecom lines, network links, auxiliary devices, all registered SIP endpoints, and their recorded voicemails) from the failed UCM6510 to the hot-standby secondary UCM6510 within only 10-50 seconds depending on the number of SIP endpoints registered.

Thanks to its smart monitoring and automated failover capabilities, the HA100 offers the ideal high-availability solution for Grandstream’s UCM6510 IP PBX for maximum complete system reliability and uptime.
