Common Extension Numbering For Multiple Pbxs - Panasonic KX-NS500 Features Manual

4.3.2.2 Common Extension Numbering for Multiple PBXs

Description
Multiple PBXs in separate locations, connected in an IP network, can share a common block of extensions
designated in a gateway group.
1) Extn. 105 dialled
PBX A in Office A
Extn. 101
Extn. 103
Extn. 104
Explanation:
In the same way as when connected by a TIE Line, if a dialled number is not found at the local PBX, the call
can be sent to other PBXs connected via an IP network. When an extension number is dialled, the PBX first
searches local extensions for a matching number. If there is no match, the PBX then checks the TIE Line
Routing Table for the Gateway Group for a corresponding entry. If an entry is found, the call is sent to the
connected PBX.
Conditions

System programming is required to enable this feature.
•
If the called extension does not exist at the called PBX, the next PBX in the same gateway group is called

•
To use this feature, all PBXs in the IP network must be KX-NS series PBXs, or KX-NCP/KX-TDE series
