A routing client (also known as a switch leg peripheral). In other words, each peripheral
device which can act as a switch leg must have its own label, even if the digit strings are
the same in all cases.

Unified ICME Release 7.1(1) introduced Network VRU Type 10, which simplifies the
configuration of Network VRU’s for Unified CVP. For most call flow models, a single Type
10 Network VRU can take the place of the Type 2, 3, 5, 7, or 8 Network VRUs, which were
associated with the Customer Instance and/or the Switch and VRU leg peripherals. The
VRU-Only call flow models still require Type 8; however, in one specific case Type 3 or 7 is
still required.

Network VRU configuration entries themselves have no value until they are associated with
active calls. There are three places in Unified ICME where this association is made:

•

Advanced tab for a given peripheral in the ICM Configuration Manager's PG Explorer tool

•

Customer Instance configuration in the ICM Configuration Manager's ICM Instance Explorer
tool

•

On every VRU Script configuration in the ICM Configuration Manager's Network VRU
Script List tool

Depending on the call flow model, Unified ICME looks at either the peripheral or the customer
instance to determine how to transfer a call to a VRU. Generally speaking, Unified ICME
examines the Network VRU which is associated with the switch leg peripheral when the call
first arrives on a switch leg, and the Network VRU which is associated with the VRU leg
peripheral when the call is being transferred to VRU using the Translation Route mechanism.
It examines the Network VRU, which is associated with the Customer Instance or the default
Network VRU from the System Information tool, when the call is being transferred to the VRU
using the Correlation ID mechanism.

Unified ICME also examines the Network VRU which is associated with the VRU Script every
time it encounters a RunExternalScript node in its routing script. If Unified ICME does not
believe the call is currently connected to the designated Network VRU, it will not execute the
VRU Script.

Note: The previously recommended VRU types still work as before, even in Unified ICME
7.1(1) and later; however, new installations must use Type 10 if possible, and existing
installations can optionally switch to Type 10.

Design (SRND) and each call flow model's configuration instructions in this chapter for detailed
information.
