This chapter briefly describes the deployment models that you
can use with Unified IP IVR.
The following are brief descriptions of key items for a
Unified IP IVR deployment:
Voice Gateway: Connects the Unified Communications network to the
Public Switched Telephone Network (PSTN) and to other private telephone
systems. You must purchase gateways separately. Both inbound and outbound calls
to the PSTN travel through the gateway.
Unified CM: Provides the features that are required to implement
IP phones, manages gateways, and directs Voice over IP traffic to the Unified
CCX system. You must purchase Unified CM separately.
Unified IP IVR: Contains the Unified CCX Engine that runs Unified
The following optional, dedicated servers for a Unified IP IVR
MRCP TTS: A dedicated, vendor-specific server that converts
text into speech and plays it back to the caller.
MRCP ASR: A dedicated, vendor-specific server that performs
Unified IP IVR can be deployed in your IP network on Cisco
Media Convergence Servers or Cisco approved customer-provided servers. However,
Unified IP IVR cannot be connected to Unified CM across a WAN.
The following four figures illustrate the different ways you
might deploy Unified IP IVR:
The first two figures show how you can deploy Unified IP IVR,
without Unified CCE.
The second two figures show how you can deploy Unified IP IVR with
The following Unified IP IVR deployment models show Unified
IP IVR deployed apart from Unified CCE.
The following figure shows Unified IP IVR installed on a
separate server. The following are brief descriptions of key items in the
Gateway. Connects the enterprise Unified Communications network to
the Public Switched Telephone Network (PSTN) and to other private telephone
systems such as Public Branch Exchange (PBX). You purchase gateways separately.
Both voice and web correspondence travel through the gateway.
Unified CM Server. Provides the features that are required to
implement IP phones, manage gateways, provides failover and redundancy service
for the telephony system, and directs voice over IP traffic to the Cisco
Unified Contact Center Express system. You must purchase Unified CM separately.
Unified IP IVR and CM have to be installed on separate servers.
Cisco Unified CCX Server. Contains the Unified CCX Engine that
runs Unified IP IVR.
Figure 1. Unified IP IVR Architecture without Unified CCE
The figure below shows how you can deploy Unified IP IVR
apart from Unified CCE. This figure expands the focus to a Unified CM cluster
and depicts the possibility of having a single Unified CCX server with optional
ASR and TTS servers.
In addition to the Unified CCX servers shown in the figure, you can
also have other Unified CCX servers. For example, you can have a separate
server for historical reporting and another separate server for the HTTP

The following figure shows how one or more Unified IP IVR
servers fit into an Unified CCE system.
Figure 3. A Unified Deployment Model within Unified CCE
The following figure shows a Unified CCE deployment model, but
focuses on the Unified CM, Unified IP IVR, and Unified CCE servers. In a
Unified CCE system, there is the Unified CM server or servers, the Unified CCX
server or servers, optional Unified CCX subsystem servers such as MRCP ASR or
MRCP TTS servers, and the Unified CCE servers.
The optional MRCP ASR and TTS software cannot be on the same server
as the Unified CCX engine and is 3rd party software, not Cisco software.
Unified IP IVR supports high availability failover between
two Unified CCX servers but not between a cluster of servers. You can also
deploy multiple Unified CCX servers (with Unified IP IVR) and let Unified CCE
manage the load balancing and failover between them. If one of the IVRs fails,
the Unified CCE system will detect the failure, stop sending calls to the
failed system, and instead send those calls to other Unified IP IVRs.

Services from partners
Ordering from a Cisco-authorized online partner provides
convenience for those customers that know which products best fit their needs
and require immediate delivery. If your needs require onsite design,
installation and ongoing support, a local reseller in your area could provide
those value-added services. There are multiple places to order Cisco products
online. Customers with Direct Purchasing agreements can order direct from
Cisco. There are also numerous channel partners that transact e-commerce on
their website for Cisco products. A full list of global Cisco Partners can be
Cisco's Partner Locator website. Customers at small and
medium sized business who want the convenience of online ordering can use
Cisco's Online Partners.
Depending on individual operational, maintenance, and network
level requirements, each installation has unique support requirements
throughout the network life cycle of planning, designing, implementing,
operating, and optimizing a network.
