500-444 Cisco Contact Center Enterprise Implementation and Troubleshooting Questions and Answers

 Device Management Protocol (DMP) is a protocol used between ICM Central Controller and IVR/CUCM PGs. It is used to send commands, such as to bring up a voice channel, to the PGs. OCTI, SIP, and ccagent are not protocols used between ICM Central Controller and IVR/CUCM PGs.

 The readiness for the CCE deployment can be verified in the CCE Web Admin -> Infrastructure - Inventory page. This page shows the list of machines that are part of the CCE deployment, including their roles, IP addresses, hostnames, and status. The status indicates whether the machine is online, offline, or in maintenance mode. The inventory page also allows adding, editing, or deleting machines from the system inventory. To access the inventory page, follow these steps:

• From your desktop, double-click the Unified CCE Tools icon, and then select Administration Tools.
• Double-click the CCE Web Administration link.
• In the Unified CCE Administration, navigate to Overview > Infrastructure Settings, click Inventory.

Answer: B

The sync job that runs every 10 minutes to bring back the OUT_OF_SYNC machine to the IN_SYNC state is the Automated differential sync job. This sync job compares the configuration of the Packaged CCE components on the primary and secondary nodes and applies the changes to the secondary node if there is any difference. The Automated differential sync job is enabled by default and runs every 10 minutes. It can also be triggered manually from the SPOG UI12.

 If Cisco Unified ICM sends back a label of 91919191, the caller will hear ringing. This is because 91919191 is a special label that is used by Cisco Unified Customer Voice Portal (CVP) to play a ringtone to the caller while the call is being transferred to an agent or another destination1. The ringtone is a WAV file that is stored on the media server and is configured on the CVP Operations Console and the VXML gateway1. The label 91919191 is matched by a dial-peer on the VXML gateway that invokes a ringtone service and sends the ringback.wav file to the ingress voice gateway2. The caller will hear the ringtone until the call is connected or disconnected1.

To execute a particular script that is configured using script explorer for a specific time, you need to have a dialed number mapped to a call type and in turn mapped to a scheduled script. This is because the dialed number identifies the call and associates it with a call type, which determines the routing script to be executed. The routing script can be scheduled for different versions or times using the script explorer tool. The script explorer allows you to view, modify, and schedule scripts for different call types and dialed numbers12. References: Scripting and Media Routing Guide for Cisco Unified ICM/Contact Center Enterprise, Release 12.5 (1) and 12.5 (2)1, Cisco Packaged Contact Center Enterprise Features Guide, Release 12.0 (1)2.

The Single Pane of Glass (SPOG) is the web-based administrative interface that should be deployed to provide a unified and simplified view of the Unified CCE system, even though Unified CCE provides Configuration Manager as the legacy User Interface for administrators1. The SPOG is also known as the CCE Web Administration or the Unified CCE Administration console, and it allows administrators to configure and manage various Unified CCE features and settings, such as agents, attributes, precision queues, bucket intervals, media routing domains, license, bulk jobs, deployment type, system information, single sign-on, context service, and contact center AI23.

The other options are incorrect because:

• A: WebSetup is not a web-based administrative interface, but rather a tool that is used to install and configure the web setup components, such as the web setup database, the web setup service, and the web setup client, on the Unified CCE servers. WebSetup is used to perform initial configuration tasks, such as setting the deployment type, the instance name, the security mode, the license server, and the LDAP directory4.
• B: Contact Centre Management Portal (CCMP) is not a web-based administrative interface for Unified CCE, but rather a separate product that provides a web-based interface for managing Cisco Unified Contact Center Express (UCCX) and Cisco Unified IP Interactive Voice Response (IP IVR) systems. CCMP allows administrators to perform tasks such as creating and modifying scripts, applications, triggers, teams, skills, and CSQs, as well as monitoring and reporting on the system performance and agent activity5.
• C: LDAP Plugin is not a web-based administrative interface, but rather a component that enables Unified CCE to integrate with an external LDAP directory, such as Microsoft Active Directory, for user authentication and authorization. LDAP Plugin allows Unified CCE to synchronize user data from the LDAP directory and assign roles and permissions to the users based on their LDAP group membership2.

The Active and Configured CUIC Users for the 2K deployment model are 200 and 800 respectively. This means that the CUIC server can support up to 200 concurrent users and up to 800 configured users. A concurrent user is a user who is logged in to CUIC and actively using the application. A configured user is a user who has an account in CUIC, regardless of whether they are logged in or not. The 2K deployment model is one of the UCCE deployment types that defines the maximum number of agents, supervisors, and reporting users that can be supported by the system. The 2K deployment model can support up to 2000 agents, 200 supervisors, and 200 CUIC concurrent users12. References:

A PCCE initialization under Unified CCE PG performs the following two tasks among others:

• Creates the CUCM Peripheral Gateway (PG) with the CUCM PIM. A CUCM PG is a component that communicates with the Cisco Unified Communications Manager (CUCM) to control and monitor agent phones and route calls. A CUCM PIM is a process that runs on the CUCM PG and acts as an interface between the CUCM and the CTI Server. The PCCE initialization creates the CUCM PG with the CUCM PIM and configures the required settings, such as the JTAPI username and password, the CUCM cluster ID, and the PG ID12.
• Downloads JTAPI from the Unified Communications Manager and installs it on the Unified CCE PG. JTAPI is a Java API that enables computer telephony integration (CTI) applications to interact with the CUCM. The PCCE initialization downloads the JTAPI client from the CUCM publisher and installs it on the Unified CCE PG. This allows the CUCM PIM to use JTAPI to control and monitor agent phones and route calls13.

The PCCE production deployment model on an ESXi server requires two validations: ensuring that the correct servers are on the correct sides and verifying that the correct RAM and CPU are being deployed. These validations are necessary to ensure that the PCCE components are configured properly and have sufficient resources to run smoothly. The other options are not relevant for the PCCE production deployment model on an ESXi server. Linux verification for containers is not applicable because PCCE does not use containers. The hypervisor provides enough power is not a validation step, but a prerequisite for the ESXi server. The lab is deployed properly is not a validation for the production deployment model, but for the lab deployment model. References: Virtualization for Cisco Packaged CCE Release 11.6(x)1, Deployment Type Info API2.

• Option A is correct because if one side of the ICM Logger fails, the other side can still receive historical data from both sides of the ICM Router. However, the failed side will not be able to receive any data until it is restored1.
• Option B is correct because the Peripheral Gateways (PGs) are connected to both sides of the ICM Router through the private LAN and the visible network. If the private LAN fails, the PGs can use the visible network to communicate with the active ICM Router and determine which side is the master2.
• Option D is correct because the ICM Router uses heartbeats to monitor the status of its duplex pair. If one side does not receive a heartbeat from the other side within a specified time interval, it assumes that the other side has failed and initiates a failover process3.
• Option C is incorrect because if one side of the ICM Logger fails, the impact of call processing is not limited to the corresponding side of the ICM Router. The ICM Router can still process calls using the data from the surviving ICM Logger side1.
• Option E is incorrect because there is some impact on call processing during an ICM Logger failure. For example, some historical reports may not be available, some configuration changes may not be replicated, and some call data may be lost4.
• Option F is incorrect because during an ICM Router failover, calls in progress in Cisco Unified Customer Voice Portal (CVP) are not disconnected. The CVP uses the Survivable Remote Site Telephony (SRST) feature to maintain the calls until the failover is completed5.

 Active Directory (AD) is a directory service that provides centralized authentication, authorization, and management of users, computers, and resources in a network. AD is based on a hierarchical structure of domains, trees, and forests, where each domain represents a logical administrative unit with its own security policies and replication scope. AD also supports site topology, which defines the physical structure of the network based on locations and network links. Some of the considerations for AD are:

• Read-Only Domain Controllers (RODC) are supported. An RODC is a domain controller that hosts a read-only copy of the AD database and does not accept any changes from clients. RODCs are useful for improving security and performance in remote or branch offices that have unreliable or slow network connections to the main office. RODCs can also cache credentials for specific users and groups, and provide local authentication services without exposing the entire AD database12.
• Supports multi-domain, single AD Forest topology. A forest is a collection of one or more AD domains that share a common schema, configuration, and global catalog. A forest can have multiple domains that are organized in a tree structure, where each domain has a trust relationship with its parent domain. A multi-domain, single forest topology allows for administrative autonomy, scalability, and flexibility in managing different domains within the same organization. For example, a company can have separate domains for different regions, departments, or business units, and still share common resources and services across the forest34.

External voice DNs are sourced from CUCM in a CCE Dial Plan. External voice DNs are the DNs that are not associated with any CCE device, such as agent phones, VRU peripherals, or gateways. They are used to route calls to destinations outside the CCE network, such as PSTN numbers, voicemail, or other PBXs. CUCM is responsible for provisioning and managing these DNs and assigning them to the appropriate devices or trunks. CVP can also use external voice DNs to send calls to CUCM for further routing or treatment.

 To use microapps in Cisco Unified CVP Comprehensive mode, the following core components are required12:

• CUCM: CTI Route Point and SIP Trunk. The CTI Route Point is used to trigger the ICM routing script when a call arrives at CUCM. The SIP Trunk is used to send the call to CVP for further treatment by the ICM script1.
• ICM: CVP Type 2 VRU and Network VRU labels. The CVP Type 2 VRU is a configuration option in ICM that allows the ICM script to send instructions to CVP using microapps. The Network VRU labels are used to route the call from CUCM to CVP via the SIP Trunk1.
• VXML Gateway: The VXML Gateway is used to execute the microapps that are sent by the ICM script. The VXML Gateway communicates with CVP using HTTP and plays the media files that are stored on the CVP Media Server1.

Option A is incorrect because it uses CTI Route Port instead of CTI Route Point, and it includes CUBE, which is not required for microapps. Option C is incorrect because it uses CTI Route Port instead of CTI Route Point, and it uses CVP Type 10 VRU, which is not supported for microapps. Option D is incorrect because it uses CVP Type 10 VRU, which is not supported for microapps1.
