You may see any of the following in the Scope column:
• Global—The extension has been published to all member systems within the same
VoIP domain. Every extension in the domain can dial and ring this number.
• Local—The extension has not been published to the VoIP domain. Only extensions
in the same system can dial and ring this number.
• Not Found—The extension is not a Global extension and is not created in the
selected system as Local. The extension number is used by other member systems
as a local extension.
• Remote—The word Remote in the Scope column tells that the selected system
maintains this extension in the extension list because it is a Global extension of
another member system. If you see an extension whose Type is Remote in the
Extension Scope window, you can only see the extension information. You cannot
configure any tabs because it is created in another system.
• Conflict—Conflict happens when one of the following situations has occurred:
• The same extension number exists as a Global extension in one member system
and as a Local extension in other systems.
• The same extension number was created as a Global extension in different
systems before the VoIP domain was formed.
The following example may help you conceptualize the multi-site extension scope.
Suppose you have three systems in different locations connected over the IP
network. The numbering for System A is 1xx; System B is 2xx, and System C is 3xx.
System A is configured as the VoIP domain Master. Assuming there is no conflict ,
the following table shows the Scope relationship of Global vs. Remote:
In the event that multiple systems have a same extension or group number created, the
following situations may occur:
Ext
System A
(VoIP domain Master)
System B System C
100 Global Remote Remote
200 Remote Global Remote
300 Remote Remote Global
