Overview of Unified CVP Call Flow Models

The following table provides the list of Unified CVP call flow models and their respective
description.

In this call flow model, the VXML Server is a J2EE-compliant server
that provides a complete solution for rapidly creating and deploying

dynamic VoiceXML applications. You can install the VXML Server
as a standalone component, without Unified ICME, the Unified CVP
Call Server, or H.323 Service components.

This call flow model is the same as the Unified CVP VXML Server
(standalone) call flow model, except that it has the additional capability
of invoking a routing script in Unified ICME and receiving a response.

In this call flow model, Unified CVP only provides Unified ICME
with VoIP call switching capabilities. You provide your own Service

Control VRU, if you are using Unified ICME to queue calls or you
might queue calls directly on your ACD. Calls might be transferred
multiple times, from Ingress, to customer-provided VRU, to either
Unified CCE or customer-provided ACD or agent, and back again.
When calls are connected to customer-provided equipment (either
VoIP or TDM), their voice paths must go to an egress gateway, which
is connected by TDM to that equipment. If the signaling is SIP, then
this call flow model works with customer-provided SIP endpoints
which have been tested and certified to interoperate with Unified CVP.

Note: The Call Director call flow model is the most inclusive call flow
because it potentially incorporates all components of the Unified CVP
solution.

In this call flow model, Unified CVP only provides the Network
Applications Manager (NAM) with VoIP call switching capabilities.

You provide your own Service Control VRU, if you are using the
NAM to queue calls or you might queue calls directly on your ACD.
Calls might be transferred multiple times, from Ingress, to
customer-provided VRU, to either the NAM or customer-provided
ACD or agent, and back again. When calls are connected to
customer-provided equipment, their voice paths must go to an egress
gateway, which is connected by TDM to that equipment. If the
signaling is SIP, then this call flow model works with
customer-provided SIP endpoints which have been tested and certified
to interoperate with Unified CVP.

Note: In a two-tier service bureau (carrier) configuration, the NAM is
the tier providing direct communication with the carrier PSTN. Route
