SmartWare Software Configuration Guide 40 • Call router configuration
Introduction
This chapter provides an overview of call router tables, mapping tables and call services and describes the tasks
involved in configuring the call router in SmartWare. This chapter includes the following sections:
• Call router configuration task list
• Call router configuration tasks
• Examples
There are two options for deciding where an incoming call on a CS interface is forwarded to:
• Basic interface call routing: Basic interface routing can be configured directly on the CS interfaces. It’s also
called direct call routing.
• Advanced call routing: More complex call forwarding decisions can be configured in the call router.
The call router is a very efficient and flexible tool for routing calls between CS interfaces. Based on a set of
routing criteria, the call router determines the destination (interface) for every incoming call. The forwarding
decisions and features are based on a set of routing tables, mapping-tables and call services.
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 mapping tables can be
used to modify call properties like the calling and called party numbers according to the network requirements.
Call services can be used in the routing path to observe the call state and spawn other calls. The hunt-group
