The Scope Of An Extension In The Voip Domain - Altigen AltiWare ACM 5.1 Administration Manual

Chapter 25: Enterprise VoIP Network Management
When a global extension is added to a member system, this extension can be propagated
to other networked systems in the VoIP domain automatically. This extension is
recognized as a remote extension by other systems. When a call is made to a remote
extension, it is redirected to the remote system over IP automatically.
Note:
No virtual extension configuration is needed to forward the call, as in the AltiWare
5.0A release. The AltiEnterprise VoIP domain uses the User directory combined
with the IP dialing table to resolve multi-site routing.
An extension can call a remote extension when invoking basic features such as an
extension-to-extension call, call transfer, conference, Zoomerang, and so on. Advanced
features, such as silent monitoring and barge-in, between sites are NOT supported.

The Scope of an Extension in the VoIP Domain

When an extension is added to a system in AltiWare Administrator, Extension
Configuration window, it can be defined as Global by checking the Global extension
box. If this box is not checked, the newly added extension is a local extension.
The scope of an extension shows the relationship of the extension to other member
systems. In AltiEnterprise Manager, a selected extension's scope appears on the
Resolve tab:
