Unified Contact Center Express Solution

Cisco Unified Contact Center Express (Unified CCX) meets the contact center needs of departmental, enterprise

branch, or small to medium-sized companies. Unified CCX offers easy-to-deploy, easy-to-use, highly available,

and sophisticated customer interaction management for up to 400 agents. Unified CCX enhances the efficiency,

availability, and security of customer contact interaction management in a virtual contact center. It offers

integrated self-service applications across multiple sites.

Unified CCX provides reduced business costs and improved customer response by providing a single-server,

contact-center-in-a-box deployment with the following:

• A sophisticated and distributed automatic call distributor (ACD)

• Computer telephony integration (CTI)

• Agent and desktop services

You can add the Cisco Workforce Optimization suite to provide quality management and work force

management tools to improve workforce productivity.

Unified CCX is available in Enhanced and Premium versions to better match product functions with your

business requirements. All Unified CCX solutions are tightly integrated with Unified CM.

Introduction to the Unified CCX Solution Reference Designs

This chapter discusses the reference designs that are available for Unified CCX. Use the Cisco Collaboration

Sizing Tool to help you determine the number and types of servers required for any supported deployment

model and call processing requirements. Before using that tool, it is necessary to have an understanding of

what deployment model you desire.

Cisco Unified Intelligence Center, Cisco Finesse, and Cloud Connect are deployed on the same Virtual Machine

(VM) with Unified CCX and support all the Unified CCX reference designs.

The following table depicts the reference designs that are supported in Unified CCX. These models have no

bearing on which specific server model is used. The Cisco Collaboration Sizing Tool identifies the minimum

server model required. This chapter provides general rules for design and considerations and limitations for

each of these reference designs. This information allows a Unified CCX system planner or designer to

understand what other similar reference designs are supported. This also helps to understand how to determine

the best solution for a given set of requirements.

These components are:

• Cisco Unified Work Force Management and Cisco Unified Advanced Quality Manager.

Unified CCX Reference Designs

Introduction to the Unified CCX Solution Reference Designs

Unified CCX General Rules for Design

The following rules apply when designing a Unified CCX deployment:

• When deploying for high availability (HA), the Unified CCX servers can be located in the same campus

LAN to provide server redundancy. The Cisco Unified CCX servers can also be located in different sites

separated by WAN to provide spatial redundancy.

For HA over LAN deployment, heartbeats are sent every one second and failover occurs if three consecutive

heartbeats are missed. For HA over WAN deployment, heartbeats are sent every second and failover occurs

if ten consecutive heartbeats are missed. These values are not configurable.

Note

• You can locate the Unified Communications Manager servers that run CTI Managers with which Unified

CCX communicates in the same campus LAN. In Unified CCX servers that are deployed over WAN,

for better site redundancy, deploy local Unified Communications Manager server at both sites.

• The Recording component must be redundant, if recording is used in a high availability deployment.

• All agents for a Unified CCX deployment must be using phones that register to the same Unified CM

cluster. Calls can be received from devices and callers on another Unified CM cluster (using intercluster

trunks).

• Unified CCX software versions must be the same for both the master and standby nodes in a high

availability deployment.

• Unified CCX solution works with a combination of software and hardware components, providing an

open and flexible environment for customers to execute complex scripts, custom codes, documents, and

so on. Overloading any of the software and hardware components such as virtual memory and CPU could

impact the solution performance. Review and optimize the scripts, custom codes, and documents before

they are loaded to the production setup. Also constantly monitor the system component and hardware

attributes like disk space and CPU utilization.

When deploying Advanced Quality Management and Workforce Management with Unified CCX, consider

the following guidelines:

• Advanced Quality Management and Workforce Management must be installed on separate VM from

each other and from Unified CCX. No form of coresidency is supported in this release with any other

software, such as installing on Unified CCX or installing both Advanced Quality Management and

Workforce Management on the same VM.

• Unified CCX does not support the use of third-party applications (for example, using TAPI) to control

its devices.

• For more deployment information about Workforce Management and Advanced Quality Management,

refer to the Cisco Workforce Optimization System Configuration Guide available at here:

http://www.cisco.com/en/US/products/ps8293/products_implementation_design_guides_list.html

Unified CCX Reference Designs

Unified CCX General Rules for Design

Existing Unified CCX customers with WFO licenses will have to remain on

classic licensing as WFO licenses are not supported in Smart Licensing. However,

you can move Unified CCX licenses to Smart Licensing and existing Cisco WFO

licenses to Cisco SolutionsPlus. For more information, contact Cisco Support.

Note

Reference Designs

The following sections describe the Unified CCX Reference Designs.

Single-Server Non-High Availability Reference Design

Unified CM integration with Unified CCX on a single-server nonhigh availability is for small deployments.

This reference design places a single instance of all the Unified CCX software components on the same server

and uses Informix Dynamic Server as the database server.

This reference design allows the Unified CCX Engine to fail over to a backup CTI Manager if the primary

CTI Manager fails. CTI ports and CTI route points should be grouped into device pools that have the same

primary and secondary server list as those used for JTAPI communications with the CTI Managers.

Two-Server High Availability Reference Design

This reference design can support silent monitoring and recording for agents at any WAN-connected site by

using desktop monitoring. (See the Unified CCX Compatibility related information located at:

http://www.cisco.com/c/en/us/support/customer-collaboration/unified-contact-center-express/

products-device-support-tables-list.html for a list of phones that support desktop monitoring.) It can also

support SPAN port monitoring for agents on the VLAN segment local to Unified CCX server. This reference

design provides redundancy for both recording and silent monitoring for all agents using desktop monitoring

(regardless of location) or agents on the local VLAN using SPAN port monitoring. Silent monitoring and

recording are not possible for agents who are using the Cisco Finesse IP Phone Agent at remote sites. Similarly,

silent monitoring and recording are not possible for agents at remote sites who are using phones that do not

support desktop monitoring.

This reference design allows either Unified CCX Engine component to fail over to a backup CTI Manager if

the primary server fails. CTI Ports and CTI Route Points should be grouped into device pools that have the

same primary and secondary server list as that used for JTAPI communications to the CTI Managers.

In HA deployments, historical data comes from the database located in the standby engine node. A higher

number of historical reporting sessions during operating hours is supported for HA deployments.
