Automatic Rerouting to Secondary PBX
IP terminals can switch connection from primary PBX to secondary PBX when a fault occurs to the primary
PBX.
Notice
When an IP phone connects to the PBX via a VPN using the built-in router, the IP phone cannot be rerouted
to the secondary PBX if the primary PBX fails. This is because if the PBX fails, the VPN session also fails.
Therefore, the IP phone cannot communicate with the secondary PBX at the time. In addition, when the
primary and secondary PBXs are connected to each other via a VPN using the built-in router, the same
limitation is applied.
Therefore, if automatic rerouting functionality is required for IP phones, they should be connected using
an external router instead of the built-in router.
Note

This feature is available for the following IP terminals.
–
KX-NT300 series and KX-NT500 series IP proprietary telephones
