deployments. If an SDDSN server meets the appropriate specifications, you may reuse it as
a CVP Operations Server.
CVP Reporting Servers are optional components in Unified CVP Release 4.1. If you wish
to use the reporting functionality, you must deploy an additional machine for each Reporting
Server.
Gatekeepers are not required in SIP implementations. If you are moving to SIP, you can
decommission gatekeepers or possibly convert them for use as ingress or VoiceXML gateways.
Content Services Switches may have to be added if you are moving from the Queue and
Transfer to the Comprehensive call flow model, and the call volume and desired redundancy
model calls for it.
SIP Proxy Servers and DNS Servers for SIP message routing are optional components for
SIP implementations. If you intend to use these components, you must add them to the
network. Dedicated DNS Servers for Unified CVP are not required.
Note: SIP Proxy Servers and DNS Servers cannot coreside with other Unified CVP product
components.
VoiceXML gateways will need to be added, if you are migrating from Queue and Transfer
to the Comprehensive call flow model.
Dedicated Type 2 and Type 8 CVP Call Control Servers are no longer necessary.
CVP Call Servers in Unified CVP Release 4.1 can handle more calls than could the CVP
Call Control Servers of CVP 3.1 (and earlier) releases. If you are migrating from one of those
releases, this could allow for the elimination of some servers, and the potential to turn them
to other uses. In some cases, the reduction in CVP Call Control Servers could permit the
elimination of one VRU PG pair as well. For detailed sizing information, see the

If you are using older gateway or gatekeeper hardware, the version of IOS required in this
release may no longer support that hardware, making it necessary for you to purchase new
hardware. For more details, see your IOS documentation and the Unified CVP Bill of Materials
at the following location.
