“9./0”
and assign it to the routegroup “_192168001101_192168001100” which associates with the
intra trunk “_192168001101_192168001100”
.
4.11.3.2 Case II: Stack a new IP PBX box with an existing running box
This case means that there is a standalone box up running for a while. Now you would like to add a
new box to form a cluster. Therefore, the standalone box will become a master box later.
1.
Ensure the new box has factory default settings before being stacked.
2.
Ensure the new box has TCP routing to the existing box via LAN interface if they are in different
local networks.
3.
Now, backup the IP PBX configuration on the existing box. Then restore this configuration to the
new one.
4.
On new box, remove all trunk configurations including routes and routegroups, and all Meet-me
conference configurations first.
5. Go
to
System
->
Stackable
of the new box, specify master’s IP address and click
Apply
.
6. Go
to
System
->
Stackable
of the existing box, select
Enable Master Mode
check box, enter IP
address and SIP port of the new box, and then click
Add
.
7. Click
Apply
.
8. Go
to
Service
->
IP PBX Service
of the existing box, and click
Restart
to reflect the changes.
The existing box turns to be a master box and the new box is a slave box in the cluster.
4.11.3.3 Case III: Add new slave boxes to an existing stack
Similar to Case II, you can also add more slave boxes to an existing cluster.
4.11.3.4 Remove slave boxes from stack
1. Go
to
System
->
Stackable
of the master box.
2.
Select IP address of a slave box you would like to remove in
Slave Peers
, and then click
Delete
.
3. Click
Apply
.
4. Go
to
Service
->
IP PBX Service
of the master box, and click
Restart
to reflect the changes.
The cluster no longer owns the removed box. The removed box gets off the cluster and would turn
back to be standalone. Moreover, the master box would also turn back to be standalone if all slave
boxes are removed and the cluster does not exist any more.

You probably notice IP addresses of two boxes meshed by an intra trunk determine name of the intra trunk.
In this case, the name of intra trunk from box B (192.168.1.101) toward box A (192.168.1.100) is
_192168001101_192168001100. Meanwhile, the routegroup associated with this intra trunk has the same name.
