What is a Network VRU?

A Network VRU supports ICM software's service control interface. An ICM routing script can
divert a call to a Network VRU and instruct the VRU to perform specific processing before
ICM software determines the final destination for the call.

Configuring VRUs

You configure Network VRUs through the ICM software Configuration Manager. Following
are the general steps you must take to configure VRUs before you can write routing scripts.
There are different Network VRU types. Each type represents a different architecture and call
flow. These are summarized below and described in detail in the Cisco ICM Software
Configuration Guide.

Before you can write routing scripts, you must do the following through the Configuration
Manager:

1. Configure the Network VRU.

2. Associate the Network VRU with a Network VRU Label.

3. Depending on the type of Network VRU configured (see the Cisco ICM Software

Configuration Guide) various additional items need to be configured.

4. Configure Network VRU scripts.

Note: You create and maintain VRU scripts on the VRU; however, you must define these
scripts through the Configuration Manager so that ICM software is aware of these scripts
so they can be called from ICM software routing scripts.

Network VRU Types and Script Nodes

Before a routing script can run a Network VRU script or queue a call at a Network VRU, it
might need an explicit node to force the routing client to connect the call to the Network VRU.
The node used to send the call to the Network VRU depends on the Network VRU type, as
shown in the following table:
