4.10 Firmware Upgrade
The version of the running PBX firmware could be found in System -> Firmware Upgrade. To upgrade
current firmware, click Browse to locate a release file obtained from the vendor, and click Upgrade to
have the latest version of PBX firmware.
Note: Consult with your IP PBX service provider for upgrade procedure.
Note: Do not change the firmware file name, otherwise the system will reject it.
4.11 Stackable Management
IP PBX is scalable and allows you to enlarge capacity by stacking up to four IP PBX boxes to form a
cluster.
4.11.1 Operation Modes
IP PBX provides three modes, 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, only one IP PBX box runs in master mode, and rest of boxes run in slave mode in the cluster.
For instance, with full-capacity case, there would be one master box and 3 slave boxes in a cluster.
Select System -> Stackable to see the current operation mode of each IP PBX box.
4.11.2 Consolidated Management
Stackable Management page of the master box not only indicates IP addresses of current slave boxes
in a cluster but also allows you to add new slave boxes to the cluster or remove slave boxes from the
cluster. You can simply manage a cluster in Stackable Management page of the master box.
Within a cluster, any extension/user update of configuration information to the master box would affect
all slave boxes automatically. As a result, you shall only configure the master box to take control over
the whole cluster in most cases. Meanwhile, all boxes within the same cluster share the same
registration information and work as one single box.
Note: 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.
Note: For Meet-me conferences in stack, do not enter the same room number in slave and master
boxes, though the function need to be configured respectively.
