Session Router Configuration 261
Figure 26-2: 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
The requirements for the Session Router can be summarized as:
• Route ISDN data calls to the local breakout
• Route inter-site calls to the opposite SmartNode (Node A to Node B and vice versa)
• Route international calls to Carrier “Melon”
•
Provide a fallback for all VoIP calls on the local breakout
•
Route local calls to the local breakout
•
Route national calls to carrier “Orange”
