Session Router Configuration
22.10 Example
22.10.1 Enterprise Network with Local Breakout and IP Carrier Access
Consider the following Enterprise Network.
Figure 22-2: Session Routing Example Network
Note that the SmartNodes in this Network may be owned and operated by the Company or by a
Service Provider.
Two sites A and B are connected to a broadband IP provider. The IP network is used to exchange
data and voice calls between the two sites. On the IP network there is also a PSTN gateway (Node C)
to an alternative voice carrier “Melon” that shall be used for most call destinations.
Sites A and B also have connections to the local ISDN network. This is called the local breakout
connection. The local breakout is to be used as a fallback for ISDN data connections.
We assume the following:
•
The number block for site A is 022 782 55 00 to 99
•
The number block for site B is 033 665 2 000 to 999
•
The Carrier Access Code (CAC) for “Apple” is 1055
•
The Carrier Access Code (CAC) for “Orange” is 1066
•
Carriers Apple, Orange and Melon do not support ISDN data calls (PC with ISDN Terminal
Adapter behind PBX A)
•
When calling through carrier “Melon” the CLI must not use the public number blocks of Site
A and B
•
Carrier “Orange” is to be used for national calls
•
Carrier “Apple” is to be used for calls to mobile
