Chapter 5 Outgoing Call Authority Control Service
5.1 Introduction to Outgoing Call Authority Control Service
5.1.1 Subscriber Type
Numbers with the same characteristics belong to the same type. Number
characteristics are described by the administrator through defining regular expressions.
Note that a number matching any regular expression of a subscriber type belongs to
this type.
One subscriber type can be configured with 16 regular expressions at most. The
administrator should make sure that the regular expressions configured for different
subscriber types do not conflict with each other.
5.1.2 Subscriber Role
Subscribers are defined as different roles for outgoing call right assignment. Each role
supports one or more available subscriber types. That is, a role can make calls to
subscriber numbers that belong to any of these types.
The XE IP PBX reserves a role named default, which cannot be deleted but can be
added with supported subscriber types.
One subscriber role can support up to 8 subscriber types.
5.1.3 Introduction to Outgoing Call Authority Control Service
By defining subscriber roles, outgoing call authority control service decides
subscribers’ rights to make outgoing calls. Only the administrator can set subscriber
roles. Subscribers have no right for this operation.
After a subscriber is assigned a role by the administrator, its call rights is determined as
follows:
z
If a number belongs to a subscriber type supported by the subscriber’s role, it is
allowed to be called.
z
If a number does not belong to any subscriber type supported by the subscriber’s
role, it is denied to be called.
z
If a number does not belong to any number type, it is also allowed to be called.
In the context of call authority, relationship between the subscriber, subscriber role and
number types is shown in Figure 5-1 .
