Hot Standby

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.

A redundant system can reduce the impact to your customers and users whenever you need to take the system offline to perform necessary maintenance tasks, such as nightly backups, system upgrade, etc.

Easy Configuration

It doesn’t require technical expertise to deploy the solution. With intuitive interface, it takes only a minute to do the pairing PBX server authentication. You can also check if your hot standby functions well with simple status indicators.

Prompt Notification

In event of any PBX server failure or automatic failover, your IT team will be prompted with email or phone calls. There is no gap in-between. You can fix the failed system right away while all your phone calls on the system are not impacted.
