3.7 Stackable management
IP PBX is scalable and allows you to enlarge capacity by stacking up to 4 IP PBX boxes to form
a cluster.
3.7.1 Operation modes
There are three different operation modes provided by IP PBX. They are standalone mode,
master mode, and slave mode. The default mode is standalone mode while there is no cluster and
IP PBX box works independently. Once a cluster is formed, there must be only one box running
in master mode, rest of boxes run in slave mode in the cluster. For instance, let us consider full-
capacity case, there would be one master box and 3 slave boxes in a cluster. Select Service ->
Stackable management, you can see current operation mode of each IP PBX box.
3.7.2 Consolidated management
Beside, Stackable management page of master box not only indicates IP addresses of current
slave boxes in a cluster but also allows you to add new slave boxes to cluster and remove slave
boxes from cluster. You would find you can manage a cluster simply by Stackable
management page of master box.
Within a cluster, any update of configuration information on master box would affect all of slave
boxes automatically. As a result, you do not need to configure each box in a cluster. Instead, you
shall only configure the master box to take control over the whole cluster in most cases

.
Meanwhile, all of boxes in the same cluster share the same registration information and thus they
work as one single box.
3.7.3 Configuration
The following examples illustrate how to configure a stack.
3.7.3.1 Case I: Stack multiple boxes at a time
• Ensure all of boxes have factory default setting before being stacked.
• Ensure all of boxes have TCP routing to each other via LAN interfaces if they are in
different local networks.
• Select one of them to be the master box. Others are slave boxes consequently.

However, for SIP and PSTN trunks and Meet-me conferences, you need to configure them respectively on each
box in stack. It is similar to how you configure them in standalone mode.
