Hot Standby
The Hot Standby solution provides high system availability and prevents you from the unnecessary business loss caused by unexpected server failure.
The solution consists of two PBXs with the same hardware and software, one works in the "active" state and the other works in the "standby" state. The configuration of primary server is synchronized to the secondary server in real time so that both systems contain identical information. When the primary server goes down, the secondary server can automatically and instantly take over.
