Unified CVP Comprehensive (SIP/H.323) Call Flow Model, Unified ICME

The Unified CVP Comprehensive call flow model combines the Call Director and the VRU-Only
call flow models. It provides initial prompt and collect, self service IVR, queuing, and VoIP
switching among Unified CCE and TDM agents.

In this call flow model, Unified CVP acts as the Switch, transferring the call to the Network
VRU and to agents. The Unified CVP IVR Service in the Operations Console is also configured
to work with the VoiceXML Gateway to provide VRU treatment, which might include ASR/TTS.

The Unified CVP Comprehensive call flow model requires the following components:

•

Call Server (using either SIP or H.323 call signaling)

•

Unified ICME

•

Ingress Gateway

•

VoiceXML Gateway

•

Operations Console

The following optional components can be used in this call flow model:

•

Reporting Server

•

VXML Server

•

Call Studio

•

Speech Servers

Caution: The Operations Console can only manage speech servers installed on Windows
(or AIX if supported by vendors), not on Linux. If the speech server is installed on Linux,
the server cannot be managed.

•

Media Servers

•

DNS Server

•

Content Services Switch

•

Gatekeeper

•

SIP Proxy Server (if the Call Server is configured to use SIP signaling, a SIP Proxy Server
is optional)
