VoiSmart Enterprise is the fault tolerant architecture designed by VoiSmart for its IP PBXs: it can be implemented at several levels, starting by parts duplication (power supply, RAID RAM, Hot Swap RAID for hard disks, etc.) up to an architecture featuring two complete systems, either in Master – Slave configuration, or in a Multimaster structure, with load balancing features.
Target: Corporates, Call centers, PA, critical telephony applications.
In a Master-Slave configuration, whenever the Master, who holds control on the service, is out of service, a software failover control system will start the Slave unit in very short time (<3 sec), keeping the service alive. In a Multimaster configuration, each equipment shares a part of the total traffic, and in case of failure of one unit, the other systems will take care of its part of the load.
An alerting procedure will also check the status of the Slave during Master-driven operations, providing an alarm in case of negative response from the Slave.
