Cisco Cisco Unified Customer Voice Portal 10.5(1) Guide De Montage

An example of a Unified CVP deployment (VXML Servers, Call Servers, Reporting Servers,
and the call paths) is illustrated below.

Figure 25: CVP Servers and Call Paths

The figure shown above depicts two logical CVP units. They are logical units because there is
no path for the call to move from one unit to the other.

•

CVP unit 1 - VS1, VS2, CS1, CS2, RS1

•

CVP unit 2 - VS3, VS4, CS3, CS4, RS2

The following scenario is an example of how you might upgrade a CVP unit.

Scenario 1: Upgrade a CVP unit of related servers in a maintenance window

•

Maintenance Window 1 - RS1, CS1, CS2, VS1, VS2

•

Maintenance Window 2 - RS2, CS3, CS4, VS3, VS4

You can upgrade each logical unit independently. Upgrading a CVP unit can be divided further
using the multiphased upgrade strategy, which is described in the following section.

Multiphased Upgrades

A multiphased upgrade refers to the ability to upgrade a subset of Unified CVP servers and
resume call processing. A multiphased upgrade process provides you with additional ways to
divide your upgrades over time. If a CVP deployment has multiple CVP units, each unit can be
upgraded using a multiphased approach.
