Cisco Cisco Customer Voice Portal 8.0(1) Guia Do Desenho

The following components of the Unified CVP solution are not part of the Unified CVP product but are 
still required for a complete solution:

The following sections discuss each of these components in more detail. Depending on the particular 
deployment model you choose, some of the above components might not be required.

The following topics describe the Cisco Unified Customer Voice Portal (CVP) product components.

A Unified CVP server can, optionally, be part of the enterprise domain.

The Unified CVP Call Server (Call Server) component provides the following independent services, 
which all run on the same Windows 2003 server:

SIP Service

This service communicates with the Unified CVP solution components such as the SIP Proxy 
Server, Ingress Gateway, Unified CM SIP trunks, and SIP phones.

The SIP service implements a Back-to-Back User Agent (B2BUA). This B2BUA accepts SIP invites 
from ingress voice gateways and typically directs those new calls to an available VoiceXML gateway 
port. After completing call setup, the Unified CVP B2BUA acts as an active intermediary for any 
subsequent call control. While the Unified CVP SIP signaling is hairpinned through this service, this 
service does not touch the RTP traffic.
