25 • Session router configuration

Introduction

This chapter provides an overview of Session Router tables and number manipulation functions and describes
the tasks involved in configuring the Session Router in SmartWare.
There are two options for deciding where an incoming call on a CS interface is forwarded:
• Basic interface call routing: Basic interface routing can be configured directly on the CS interfaces. It is also
called direct call routing.
• Advanced session routing: More complex call forwarding decisions can be configured in the session router
The Session Router is a very efficient and flexible tool for routing communication sessions between CS inter-
faces. Based on a set of routing criteria the Session Router determines the destination (interface) for every
incoming call. The forwarding decisions and features are based on a set of routing tables and number manipu-
lation functions.
Each routing table is responsible for a specific routing criterion such as the called party number or the bearer
capability of the call. Multiple tables can be linked together to form a decision tree. The number manipulation
functions can be used to modify the calling and called party numbers according to the network requirements.
Figure 61 illustrates direct call and advanced session routing. In this chapter advanced session routing is
explained. For configuring direct call routing refer to chapter 24,
