Unified CVP VRU Call Flow Models with NIC Routing

This section describes the call flows and provides configuration instructions for the following
Unified CVP call flow models:

•

•

•

Note: Be aware that in VRU-Only mode, Unified CVP by itself does not provide queuing
capability; however, it can hold calls being queued when used with Unified ICME/Unified CCE
with appropriate Unified ICME network interface controllers.

Type 8 Unified CVP VRU-Only Call Flow Model, Unified ICME

In this call flow model, Unified CVP works with the Voice Gateway to act as the VRU; VRU
voice treatment is provided by the Gateway and can include ASR/TTS.

When deployed with a NIC being used to queue and transfer calls (VRU Type 8), the NIC
interfaces to the TDM switch or to the PSTN to transfer the call to an agent.

Note: Neither the Unified CVP H.323 Service nor the Unified CVP SIP Service are part of this
call flow model.

The Unified CVP VRU-Only call flow model requires the following components:

•

Call Server with IVR and ICM Services enabled

•

VoiceXML Gateway

•

Operations Console

•

Unified ICME

Note: The VXML Server and the Reporting Server are optional.

The following figure shows the call flow for the Type 8 call flow model; in this figure, the NIC
transfers the call.

Note: In the following diagram, solid lines indicate voice paths and dashed lines indicate
signaling paths.
