Defining Incoming and Outgoing Access
In addition to defining CUG member address values, you can also define the incoming
and outgoing access attributes that complete the CUG member rule.
•The incoming access (IA) attribute enables you to define how a CUG member
handles calls coming from other CUGs or non-CUG users. A user mapping to a
CUG member with incoming access enabled can receive calls coming from
non-CUG users, as well as calls coming from other CUGs. If you disable
incoming access, the CUG member can only receive calls from other members of
the same CUG.
•The outgoing access (OA) attribute enables you to define how a CUG member
handles calls to other CUGs and non-CUG users. A user mapping to a CUG
member with outgoing access enabled can make calls to other CUGs and
non-CUG users. If you disable outgoing access, the CUG member can only make
calls to other members of the same CUG.
For example, the following CUG member rule applies to E.164 addresses beginning
with digits 1508:
Users that map to this rule can receive calls from members of their own CUG,
members of other CUGs, and non-CUG users (incoming access is enabled), but they
cannot make calls outside their own CUG.
Developing CUGs
For each CUG you create, you can assign up to 128 different member rules; you can
use an individual member rule in up to 16 different CUGs. In this way, a CUG is made
up of all users that map to the addresses that these rules define. You can configure up
to 1024 CUGs per switch.
When you create a CUG (“CUG A”), the attributes you configure for each CUG
member rule (“Rule1”) that you associate with the CUG define how the CUG handles
calls between members. For example, if you enable the incoming calls barred (ICB)
attribute for Rule1, users that map to Rule1 cannot receive calls from other CUG A
members. Conversely, disable ICB to allow users that map to Rule1 to receive calls
from other CUG A members.
