This chapter describes the Cisco Unified Contact Center solutions available with the Cisco Unified Communications System. It includes information on Cisco products such as Cisco Unified Contact Center Express, Cisco Unified Contact Center Enterprise, and Cisco Unified Customer Voice Portal. It also covers the design considerations for deploying these Cisco Unified Contact Center products with Cisco Unified Communications Manager and other Unified Communications components.
This chapter covers the following topics:
This chapter starts with a high-level overview of the main Cisco Unified Contact Center Portfolio. Then it covers the various Unified Communications deployment models for contact centers. Finally, it discusses design considerations on topics such as bandwidth, latency, Cisco Unified Communications Manager integration, and sizing.
The intent of this chapter is not to provide details on each contact center product and their various components but rather to discuss the design considerations for their integration with the Cisco Unified Communications System. Detailed design guidance for each Unified Contact Center product is covered in specific Solution Reference Network Design (SRND) guides for the Cisco Unified Contact Center Express, Cisco Unified Contact Center Enterprise, and Cisco Unified Customer Voice Portal products. These product-specific SRNDs are available at
Table 24-1 lists the topics that are new in this chapter or that have changed significantly from previous releases of this document.
Other minor updates for Cisco Collaboration Systems Release 10.0
This chapter discusses the following main Cisco Contact Center products and related features:
The Cisco Unified CM call queuing feature provides the capability for queuing the incoming callers to a hunt pilot number. With this option enabled, callers to the hunt pilot can be put in queue to wait for an available agent that is configured as a hunt member to answer the call. Callers receive an initial greeting announcement when they first enter the queue, and they hear periodic announcements while they are in queue. When an agent becomes available, the call is taken out of the queue and answered by the agent. For customers who need a basic contact center with very limited functionality, Cisco Unified CM call queuing can be an option. However, unlike the full-featured Cisco Contact Center products, the Unified CM call queuing option lacks much of the contact center functionality such as agent desktop, supervisor, and reporting capabilities. If customers require complete contact center functionality, Cisco Unified Contact Center Enterprise or Cisco Unified Contact Center Express should be used.
The hunt pilot line members can display the queue status about their associated hunt pilots from the phone screen, and the queue status provides the following information:
In addition, Unified CM call queuing provides statistics on the number of calls currently waiting in queue and the longest call waiting time, along with other statistics, through the serviceability counters based on the hunt pilot number. This allows the supervisor to monitor the queue status using the Real Time Monitoring Tool (RTMT). For details on the serviceability counters, refer to the latest version of the Cisco Unified Communications Manager Features and Services Guide, available at
For each hunt pilot, callers can be routed to an alternate configurable destination such as voicemail or another hunt pilot if any of the following situations occurs:
Note For calls routed to the queue-enabled hunt pilot number through a SIP trunk, the SIP Rel1XX Options should be set to Send PRACK if 1XX contains SDP in the SIP profile associated with the SIP trunk.
For additional information on the Unified CM call queuing option, refer to the latest version of the Cisco Unified Communications Manager Features and Services Guide, available at
Cisco Unified Contact Center Enterprise (Unified CCE) provides a VoIP contact center solution that enables you to integrate inbound and outbound voice applications with Internet applications, including real-time chat, Web collaboration, and email. This integration provides for unified capabilities, helping a single agent support multiple interactions simultaneously, regardless of the communications channel the customer has chosen. Because each interaction is unique and may require individualized service, Cisco provides contact center solutions to manage each interaction based on virtually any contact attribute. The Unified CCE deployments are typically used for large size contact centers and can support thousands of agents.
There is also a predesigned, bounded deployment model of Unified CCE: Cisco Packaged Contact Center Enterprise (Packaged CCE). Customers whose contact center requirements fit the boundaries of the solution can enjoy the advantages of the simplified management interface, smaller hardware footprint, and reduced time to install. Those customers can also benefit from the comprehensive feature set of Cisco Unified Contact Center Enterprise and Cisco Unified Customer Voice Portal. The solution comes packaged with Cisco Unified Intelligence Center for comprehensive reporting and Cisco Finesse desktop software for an enhanced, next-generation desktop experience. For more details on Packaged CCE, refer to the documentation at the following locations:
Unified CCE employs the following major software components:
The Call Router makes all the decisions on how to route a call or customer contact.
The Logger maintains the system database that stores contact center configurations and temporarily stores historical reporting data for distribution to the data servers. The combination of Call Router and Logger is called the Central Controller.
The Peripheral Gateway (PG) interfaces to various "peripheral" devices, such as Cisco Unified CM, Cisco Unified IP Interactive Voice Response (Unified IP IVR), Cisco Unified CVP, or multichannel products such as Cisco Unified Web Interaction Manager (Unified WIM) and Cisco Unified E-Mail Interaction Manager (Unified EIM). A Peripheral Gateway that interfaces with Unified CM is also referred to as an Agent PG.
The CTI Server and CTI Object Server interface with the agent desktops. Agent desktops can be based on the Cisco Agent Desktop (CAD) solution, Cisco CTI Desktop Toolkit, or customer relationship management (CRM) connectors to third-party CRM applications.
The Administration & Data Server provides a configuration interface as well as real-time and historical data storage.
The Cisco Unified CCE solution is based on the integration with Cisco Unified Communications Manager (Unified CM), which controls the agent phones. For deployments without Unified CM but with traditional ACD, use Cisco Unified Intelligent Contact Management Enterprise (Unified ICME) instead of Unified CCE.
The queuing and self-service functions are provided by Cisco Unified IP Interactive Voice Response (Unified IP IVR) or Cisco Unified Customer Voice Portal (Unified CVP) and are controlled by the Unified CCE Call Router.
Most of the Unified CCE components are required to be redundant, and these redundant instances are referred to as side A and side B instances. For example, Call Router A and Call Router B are redundant instances of the Call Router component running on two different virtual machines.
Agents can use a large variety of endpoints, including some video endpoints and some Cisco TelePresence endpoints such as the Cisco TelePresence System EX60 and EX90. For a list of supported endpoints, refer to the Compatibility Matrix for Unified CCE, available at
Cisco Unified Customer Voice Portal (Unified CVP) provides carrier-class voice and video IVR services on Voice over IP (VoIP) networks. It can perform basic prompt-and-collect or advanced self-service applications with CRM database integration and with automated speech recognition (ASR) and text-to-speech (TTS) integration. Unified CVP also provides IP-based call switching services by routing and transferring calls between voice gateways and IP endpoints.
Unified CVP is based on the Voice Extension Markup Language (VXML), which is an industry standard markup language similar to HTML and which is used to develop IVR services that leverage the power of web development and content delivery.
The Unified CVP solution employs the following main components:
The Unified CVP Call Server provides call control capabilities for SIP and H.323 through the SIP and H.323 services. The Unified CVP Call Server can also integrate with the Unified CCE Call Router through the Intelligent Contact Management (ICM) service. The IVR service provides a platform to run VXML Micro applications and to create VoiceXML pages.
This component executes complex IVR applications by exchanging VoiceXML pages with the VoiceXML gateway's built-in voice browser. Unified CVP VXML applications are written using Cisco Unified Call Studio and are deployed to the Unified CVP VXML Server for execution. Note that there is no RTP traffic going through the Unified CVP Call Server or the Unified CVP VXML Server.
The Cisco Voice Gateway is the point at which a call enters or exits the Unified CVP system. The Cisco Voice Gateway could have a TDM interface to the PSTN. Alternatively, Cisco Unified Border Element could be used when the interface to the PSTN is an IP voice trunk.
The VoiceXML Gateway hosts the Cisco IOS Voice Browser. This component interprets VoiceXML pages from either the Unified CVP Server IVR Service or the Unified CVP VXML Server. The VoiceXML Gateway can play prompts based on.wav files to the caller and can accept input from the caller through DTMF input or speech (when integrated with Automatic Speech Recognition). It then returns the results to the controlling application and waits for further instructions.
The Cisco VoiceXML Gateway can be deployed on the same router as the Cisco Voice Gateway. This model is typically desirable in deployments with small branch offices. But the VoiceXML Gateway can also run on a separate router platform, and this model might be desirable in large or centralized deployments with multiple voice gateways.
A video media server in a Unified CVP comprehensive deployment enables video streaming for the Video in Queue feature. Cisco MediaSense or Cisco TelePresence Content Server can be used as a video media server.
Unified CVP can be deployed standalone or integrated with Unified CCE to offer voice and video self-service and queuing functions. The Unified CVP solution now supports the G.711 a-law codec end-to-end.
The Basic Video Service in Unified CVP is available when Unified CVP is deployed along with Cisco Contact Center Enterprise (Unified CCE) in a comprehensive deployment model. This service allows a video caller to interact with an audio-only IVR and subsequently connect with a video agent. It supports Cisco TelePresence endpoints such as the Cisco TelePresence System EX60 and EX90 as customer and agent endpoints. The video agents can also conference in a second audio-only agent by dialing a direct extension from their phone.
The Video in Queue (VIQ) Basic Video is an optional feature in Unified CVP, and it can be enabled on Unified CVP to allow the caller to interact through high-definition video prompts or navigate a video menu using DTMF keys. Cisco MediaSense or Cisco TelePresence Content Server enables the video streaming. The caller can subsequently connect to a video agent. Unified CVP supports only specific Cisco TelePresence endpoints (Cisco TelePresence System 500 Series, EX60, and EX90) for the caller when this feature is enabled.
For more information on Unified CVP system design and detailed call flows, refer to the latest version of the Cisco Unified Customer Voice Portal Solution Reference Network Design (SRND), available at
Cisco Unified Contact Center Express (Unified CCX) meets the needs of departmental, enterprise branch, or small to medium-sized companies that need easy-to-deploy, easy-to-use, highly available and sophisticated customer interaction management for up to 400 agents. It is designed to enhance the efficiency, availability, and security of customer contact interaction management by supporting a highly available virtual contact center with integrated self-service applications across multiple sites.
Unified CCX integrates with Unified CM by means of JTAPI for call control. All the Unified CCX components, including the Unified CCX engine, Unified CCX database, CAD Server, Unified CCX Outbound Dialer, and Express E-mail Manager, are installed on a single virtual machine. For system redundancy, a second identical Unified CCX instances can be added to the deployment.
Unified CCX has built-in email, outbound dialer, and agent silent monitoring and recording capabilities. It supports advanced features such as Automated Speech Recognition (ASR) and Text to Speech (TTS), HTTP, and VXML. It also supports products such as Cisco Unified Workforce Optimization to optimize performance and quality of the contact center. Agents can use a variety of video endpoints such as the Cisco Unified IP Phone 9900 Series with camera. For a list of supported endpoints, refer to the latest version of the Software and Hardware Compatibility Guide for Cisco Unified CCX, available at
Cisco Unified IP IVR shares the same software architecture as Unified CCX. It provides prompting, collecting, and queuing capability for the Unified CCE solution. It could also be used as a standalone self-service application.
Cisco SocialMiner is a social media customer-care solution that can help you proactively respond to customers and prospects by communicating through public social media networks such as Twitter, Facebook, or other public forums or blogging sites. By providing social media monitoring, queuing, and workflow to organize customer posts on social media networks and deliver them to your social media customer care team, your company can respond to customers in real time using the same social network the customers are using. For more information, refer to the documentation available at
Cisco Contact Center products have built-in administration and management capabilities. For example, Unified CCE can be administered with the Configuration Manager tool that is installed with Unified CCE, and Unified CVP can be administered with the Unified CVP Operations Console, also known as Operations, Administration, Maintenance, and Provisioning (OAMP).
In addition, Cisco Unified Contact Center Management Portal (Unified CCMP) can be deployed to simplify the operations and procedures for performing basic administrative functions such as managing agents and equipment. Unified CCMP is a browser-based management application designed for use by contact center system administrators, business users, and supervisors. It is a dense multi-tenant provisioning platform that overlays the Cisco Unified CCE, Unified ICM, Unified CM, and Unified CVP equipment.
Cisco Unified Intelligence Center (Unified IC) is the main reporting tool for the Cisco Contact Center solutions. It is supported by Unified CCE, Unified CCX, and Unified CVP. This platform is a web-based application offering many Web 2.0 features, high scalability, performance, and advanced features such as the ability to integrate data from other Cisco Unified Communications products or third-party data sources.
Cisco Unified Intelligence Center gets source data from a database, such as an Unified CCE Administration & Data Server database or the Unified CVP Reporting Informix database. Reports are then generated and provided to a reporting client.
The Cisco Unified Enterprise solution supports web interaction and email interaction for multichannel support. Cisco Unified Web Interaction Manager (Unified WIM) technology helps ensure that communication can be established from nearly any web browser. Cisco Unified E-Mail Interaction Manager (Unified EIM) provides inbound email routing, automated or agent assisted email responses, real-time and historical reporting, and role-based hierarchical rights management for agents, supervisors, administrators, and knowledge base administrators.
For more design information on these products, refer to the Cisco Unified Web and E-Mail Interaction Manager Solution Reference Network Design Guide, available at
Cisco Unified Contact Center solutions provide recording and silent monitoring capabilities based on the following mechanisms:
This feature replicates the network traffic to a destination port to which a Cisco contact center server is connected.
In this case, the agent desktop receives the voice packets and sends them to a recording server or to a supervisor desktop for silent monitoring. This option is available with Cisco Agent Desktop (CAD), for example.
With this option, Unified CM is involved in setting up the recording flows and can perform call admission control for those flows. This option can be used with Cisco MediaSense, for example.
This option can be used with Cisco MediaSense, for example.
For more details on call recording and monitoring, see the chapter on Call Recording and Monitoring.
This section describes the various design models used for deploying Cisco Unified Contact Center solutions. For more details on these deployment models, refer to the Cisco Unified Contact Center SRNDs, available at http://www.cisco.com/go/ucsrnd
In this deployment, all the components such as call processing agents, voice gateways, and contact center applications are in the same site. Agents and supervisors are also located at that site. The main benefit of the single-site deployment model is that there is no WAN connectivity required and, therefore, no need to use a low-bandwidth codec such as G.729, transcoders, compressed Real-Time Transport Protocol (cRTP), or call admission control.
A multisite deployment with centralized call processing consists of a single call processing cluster that provides services for many remote sites and uses the IP WAN. Cisco Contact Center applications (Unified CCE, Unified CCX, and Unified CVP) are also typically centralized to reduce the overall costs of management and administration. Figure 24-1 illustrates this type of deployment.
Figure 24-1 Multisite Contact Center with Centralized Call Processing
Because the agents or the voice gateways in this type of deployment are located in remote sites, it is important to consider the bandwidth requirements between the sites. It is also important to carefully configure call admission control, Quality of Service (QoS), codecs, and so forth. For more information on the general design considerations for Unified Communications solutions, refer to the chapter on Collaboration Deployment Models.
Contact center deployments in a Unified Communications system typically have the following additional bandwidth requirements:
Remote agents (for example, agents working from home) are also supported with Cisco Unified Contact Center. There are mainly two solutions. The first one requires the agent to use an IP phone that is connected to the central site by a broadband internet connection. In this solution, the phone is CTI controlled by the Cisco Unified Contact Center application. The second solution is based on Cisco Unified Mobile Agent, which enables an agent to participate in a call center with any PSTN phone such as cell phone.
The model for a multisite deployment with distributed call processing consists of multiple sites, each with its own call processing cluster connected to an IP WAN. This section assumes that each Unified CM cluster has agents registered to it.
A Unified CCX deployment cannot be shared across multiple Unified CM clusters. Each Unified CM cluster requires its own Unified CCX deployment, as illustrated in Figure 24-2.
Figure 24-2 Multisite Unified CCX Deployment with Distributed Call Processing
Requirements for Unified CCE differ from Unified CCX. A single Unified CCE system can span across multiple Unified CM clusters distributed across multiple geographic locations. A Unified CCE Agent PGs must be installed in each Unified CM cluster location and could be physically remote from the Unified CCE Central Controller (Call Router + Logger). Figure 24-3 illustrates this type of deployment and highlights the placement of the Agent PG.
Figure 24-3 Multisite Unified CCE Deployment with Distributed Call Processing
If you require multiple contact center deployments, you could connect those deployments through Unified ICM by using the parent/child deployment model to form a single virtual contact center. The parent/child model provides several benefits, such as enterprise queuing and enterprise reporting across all the contact center deployments. It also provides complete site redundancy and higher scalability. For more details on the parent/child model, refer to the following documents:
Similarly to the multisite model with centralized call processing, multisite deployments with distributed call processing require careful configuration of QoS, call admission control, codecs, and so forth.
In this deployment model, a single Unified CM cluster is deployed across multiple sites that are connected by an IP WAN with QoS features enabled. Cisco Unified Contact Center solutions can be deployed with this model. In fact, the Cisco Unified Contact Center components themselves can also be clustered over the WAN.
For example, with Unified CCE, the side A components could be remote from the Unified CCE side B components and separated from them by an IP WAN connection. (For more details on Unified CCE high availability, see High Availability for Contact Centers.) The following design considerations apply to this type of deployment:
Figure 24-4 illustrates a deployment of Unified CCE using clustering over the WAN.
Figure 24-4 Unified CCE Deployment with Clustering Over the WAN
With Unified CCX and Unified IP IVR solutions, the primary Unified CCX or Unified IP IVR node could also be remote from the backup node. The requirements for Unified CCX deployments are different than the ones for Unified CCE deployments. For example, redundant WAN links are not required with Unified CCX. Also, the maximum latency between the primary and backup Unified CCX nodes is 80 ms RTT. Figure 24-5 illustrates this type of deployment. For more details, refer to the Unified CCX SRND, available at http://www.cisco.com/go/ucsrnd.
Figure 24-5 Unified CCX Deployment with Clustering Over the WAN
This section summarizes the following major design considerations for contact center deployments:
All Cisco Unified Contact Center products provide high availability. For example, with Unified CCX or Unified IP IVR, you could add a second identical Unified CCX or Unified IP IVR node to provide high availability. The second node can reside in the same data center as the primary node or, if geographic redundancy is required, the second node can reside in a different data center across the WAN from the primary node (see Clustering Over the IP WAN). One of the nodes would be the active node and would handle all the call processing. The other node would be in standby mode and become active only if the primary node fails. Unified CVP also supports high available deployments with multiple Unified CVP nodes, voice gateways, VXML gateways, SIP proxies, and so forth.
With Unified CCE, most of the components are required to be redundant, and the redundant instances are referred to as side A and side B instances. For example, Call Router A and Call Router B are redundant instances of the Call Router module (process) running on two different virtual machines. This redundant configuration is also referred to as duplex mode. The Call Routers run in synchronized execution across the two instances, which means both sides of the duplex instances process every call. Other components, such as the Peripheral Gateways, run in hot-standby mode, meaning that only one of the Peripheral Gateways is actually active at any given time.
In addition to the redundancy of the Unified Contact Center components themselves, their integration with Unified CM can also be redundant. For example, each Unified CCX or Unified IP IVR node can connect to a primary CTI Manager and also to a backup CTI Manager in case the primary CTI Manager fails. With Unified CCE, a PG side A would connect to a primary CTI Manager, while the redundant PG side B connects to the secondary CTI Manager, thus providing high availability if one CTI Manager fails.
For more details, refer to the Cisco Unified Contact Center SRNDs, available at http://www.cisco.com/go/ucsrnd.
This section describes how to provision WAN bandwidth in a multisite contact center deployment, taking into account different types of call control traffic and real-time voice traffic. It is important to understand the latency and QoS parameters because adequate bandwidth provisioning and implementation of QoS are critical components in the success of contact center deployments.
Contact center solutions require sufficient WAN bandwidth to accommodate the following main types of traffic:
Bandwidth calculations and guidelines are provided in the Cisco Unified Contact Center SRNDs, available at http://www.cisco.com/go/ucsrnd.
Agents and supervisors can be located remotely from the call processing components and the contact center. Technically, the delay between the CTI OS server and CTI OS client, as well as between the CAD server and CAD or CSD desktop, could be very high because of high time-out values. Long latency will affect the user experience and might cause confusion or become unacceptable from the user perspective. For example, the phone could start ringing but the desktop might not be updated until later.
Latency requirements between the contact center and the call processing components, and between the contact center components themselves, depend on the contact center solutions. For example, the Unified CCX redundant nodes can be located remotely from each other, with a maximum latency of 80 ms RTT. With Unified CCE, the maximum latency between the Unified CCE components and Unified CM, or between the Unified CCE components themselves, is greater than 80 ms RTT.
For more details, refer to the Cisco Unified Contact Center SRNDs, available at http://www.cisco.com/go/ucsrnd.
Similar to deployments with other Unified Communications components, contact center deployments require the configuration of Quality of Service (QoS) to prioritize time-sensitive or critical traffic. QoS marking for voice and voice signaling in a contact center environment is the same as with other Unified Communications deployments. Traffic specific to the contact center must be marked with specific QoS markings. For example, some of the traffic for the Unified CCE private network must be marked as AF31, while other traffic must be marked as AF11. The QoS marking recommendations and QoS design guidance are documented for each Unified Contact Center solution in their respective Cisco Unified Contact Center SRNDs, available at http://www.cisco.com/go/ucsrnd.
Similar to deployments with other Unified Communications components, contact center deployments require careful provisioning of call admission control. The same mechanisms described in the chapter on Call Admission Control, also apply to contact center environments.
Voice traffic associated with silent monitoring and recording might not be accounted for in the call admission control calculation. For example, voice traffic from silent monitoring and recording by Unified CM (voice traffic forked at the phone) is properly accounted for, but voice traffic from desktop-based silent monitoring (desktop connected to the back of the agent IP phone) is not counted in call admission control calculations.
Call admission control for Mobile Agent and Unified CVP involves special considerations. For more details, refer to the Cisco Unified Contact Center SRNDs, available at http://www.cisco.com/go/ucsrnd.
Observe the following design considerations apply when integrating Cisco Unified Contact Center components with Unified CM:
Figure 24-6 Deployment with One Agent PG and Four Unified CM Subscriber Pairs
The following additional design considerations apply in the situations indicated:
All deployments must be sized with the Cisco Unified Communications Sizing Tool (Unified CST). This tool performs sizing of the contact center products such as Unified CCE, Unified IP IVR, Unified CVP, and Unified CCX. It determines the contact center resources required for your deployment, such as number of agents, number of IVR ports, and number of gateway ports. In addition to performing sizing for the contact center components themselves, the tool also sizes the rest of the Unified Communications solution, including Unified CM and voice gateways. This tool is available to Cisco employees and partners only (with proper login authentication) at http://tools.cisco.com/cucst.
In general, sizing of the contact center depends heavily on the busy hour call attempts (BHCA) for calls coming into the contact center. It also depends on other parameters such as the Service Level Goal and Target Answer Time. For example, a deployment where 90% of the calls must be answered within 30 seconds will require more contact center resources than a deployment where 80% of the calls must be answered within 2 minutes. Another parameter that impacts the sizing is whether CAD or CTI OS is used, which could result in different Agent PG scalability. Use the Unified CST for sizing, and consult the respective Cisco Unified Contact Center SRNDs, available at http://www.cisco.com/go/ucsrnd, for more details.
The contact center design also impacts Unified CM sizing. The following considerations apply to sizing Unified CM when it is deployed in contact center solutions:
For more details, refer to the Cisco Unified Contact Center SRNDs, available at http://www.cisco.com/go/ucsrnd.
Cisco Contact Center products and solutions described in this chapter can be customized to create specialized solutions for a specific industry such as retail, health care, or financial enterprises. This section describes in brief a few such solutions provided by Cisco.
Cisco Remote Expert Smart Solution is a customized contact center solution that is applicable to various industries such as retail banking, manufacturing, and others. The Remote Expert Smart Solution uses skills-based routing and availability monitoring, then it connects the expert using TelePresence, voice, and content sharing technologies. The Remote Expert solution can also integrate with customer relationship management (CRM) and Common Intermediate Format (CIF) systems to provide a complete view of customer relationships and activities to the agents.
The Cisco Remote Expert Smart Solution architecture comprises three main locations:
The datacenter site hosts components that provide core call routing and processing functions. The Remote Expert Smart Solution leverages advance Unified Communications features for skills-based call routing and media sharing to complete the Remote Expert experience:
– Cisco Unified Communications Manager (Unified CM) provides basic Unified Communications functions such as call control, dial plan, and call admission control.
– Cisco Unified Customer Voice Portal (Unified CVP) and Voice XML (VXML) Gateways provide inbound call queuing and interactive voice response (IVR) services.
– Cisco Unified Contact Center Enterprise (Unified CCE) provides skills-based call forwarding to an available expert based on the customer's selected need.
The Cisco Interactive Experience Manager (IEM) and Cisco Remote Expert Manager also reside at the datacenter. There are other optional components such as Cisco MediaSense and Cisco TelePresence Manager that can reside at the datacenter if their functionality is required.
The expert location is the location of the call center agents and experts. The agent endpoint (such as the Cisco TelePresence System 500 Series, EX60, or EX90) and agent workstation reside at the expert location. The agent workstation has applications such as Agent Desktop, Collaboration Workspace, and Direct Connect installed on it.
The customer location is the location of the caller, and it typically may contain customer-facing components such as human input devices (magnetic card readers, for example), endpoints (such as Cisco TelePresence System EX60 or EX90), a Common Unix Printing System laser printer, and a collaboration pane (touch-screen monitor). The Cisco Interactive Experience Client 4600 Series (IEC 4600) device also resides at the customer location.
The Cisco Remote Expert Smart Solution supports video queuing. If an expert is not available, the call gets queued. The customer can then select videos to play on the collaboration panel while in queue. The solution can also be customized to display the in-queue video on the Cisco TelePresence screen rather than on the collaboration panel.
For more details on the architecture, design, and configuration of the Cisco Remote Expert Solution and supported call flows, refer to the Cisco Remote Expert Smart Solution documentation available at
Unified CCE is managed with the Simple Network Management Protocol (SNMP). Unified CCE devices have a built-in SNMP agent infrastructure that supports SNMP v1, v2c, and v3, and it exposes instrumentation defined by the CISCO-CONTACT-CENTER-APPS-MIB. This MIB provides configuration, discovery, and health instrumentation that can be monitored by standard SNMP management stations. Moreover, Unified CCE provides a rich set of SNMP notifications that alert administrators of any faults in the system. Unified CCE also provides a standard syslog event feed (conforming to RFC 3164) for those administrators who want to take advantage of a more verbose set of events.
For more information about configuring the Unified CCE SNMP agent infrastructure and the syslog feed, refer to the SNMP Guide for Cisco ICM/IPCC Enterprise & Hosted Editions, available at
Unified CVP health monitoring can be performed by using any SNMP standard monitoring tool to get a detailed visual and tabular representation of the health of the solution network. All Unified CVP product components and most Unified CVP solution components also issue SNMP traps and statistics that can be delivered to any standard SNMP management station or monitoring tool.
Unified CCX can also be managed with SNMP and a syslog interface.
Cisco Prime Collaboration can also help manage a Contact Center deployment. For example, Cisco Prime Collaboration Assurance can be used to monitor the number of active calls, number of inbound calls per second, or number of agents logged on.
