8 Example Provisioning
This chapter introduces several practical configuration examples of IP PBX deployment. The
configuration of IP PBX is very flexible and the expressiveness of usergroups, routegroups, and trun
are scalable enough to support various network architectures. Users could refer to these examples
and build a larger network in
8.1 Internal Extension Configuration
The procedure introduced below is recommended as th
configuration only enables internal extension calls, but it serves as a good practice for administration
․
Configure a usergroup named ALL (refer to 6.1).
․
Configure users and assign every user to usergroup AL
․
Configure devices and an extension for each device (refer to 6.3).
․
Assign each extension to a corresponding user (refer to 6.3).
․
Configure each client phone with respect to the extension number and password in its IP PBX
extension configuration accordingly.
․
Reload the IP PBX service (refer to 5.6.2).
Up to this point all configured phones should register with the IP PBX with a usable extension. Since
these phones are all belonged to the same usergroup ALL, they can call one another without limitation.
8.2 Case I: Singe-site Configuration
This case describes the typical settings of a single-site configuration; say Company A. Assume
Company A has a DSL connection for Internet access and 2 PSTN subscriber lines as shown in Figure
6-1. The provisioning tasks include:
volving multiple sites and advanced services.
