For businesses operating mission-critical services or 24/7 service center, telecommunication downtime not only imply substantial financial losses but presents a challenge to customer trust and retention. While it’s impossible to completely rule out the possibility of downtime, IT teams can implement high availability (server redundancy) solution to minimize the interruptions. And that’s exactly where Hot Standby comes into play.
What Is Hot Standby?
Basically, PBX Hot Standby pertains to a redundant implementation that allows you to create a mirroring server pair and recover immediately when failure occurs.
As a fully automated disaster recovery mechanism, PBX Hot Standby connects two identical PBX servers (the primary server and the secondary server) to enable real-time data replication and constantly monitor the operation status of both systems. When the primary server fails, the secondary server will automatically switch all system control to the secondary server. Thus, the downtime is kept to an absolute minimum and communications can continue to operate as usual. The failover is automatic and almost instantaneous. You can also bypass automatic failover and manage the transition on your own schedule.
