The service that must be restarted after modifying the Java Keystore on the CVP servers is the Cisco CVP WebServicesManager. The Cisco CVP WebServicesManager is a service that provides web services for the CVP components, such as the Operations Console, the Reporting Server, and the Call Server. The Java Keystore is a file that stores the certificates and keys for secure communication between the CVP components and other systems. If the Java Keystore is modified, the Cisco CVP WebServicesManager service must be restarted to apply the changes and ensure the proper functioning of the web services12.

Monitor mode is a feature of the Script Editor tool that allows the user to view the data flow in the script as it executes. Monitor mode displays the values of variables, labels, and expressions as the script runs. It also shows the path that the script takes through the various steps and branches. Monitor mode can be used to troubleshoot and debug scripts, as well as to verify the logic and functionality of the script. Monitor mode can be accessed by clicking the Monitor button on the toolbar or by pressing F5. References: Contact Center Enterprise Troubleshooting and Configuration - Cisco, page 17; Cisco Packaged Contact Center Enterprise Administration and Configuration Guide, Release 12.6(1), section “Scripting Specifics in a Packaged CCE Environment”.

The 2K deployment model for Cisco Contact Center Enterprise (CCE) is a prepackaged solution that offers a simplified and scalable architecture for medium-sized contact centers. The 2K deployment model supports up to 2,000 active agents and up to 8,000 configured agents. An active agent is an agent who is logged in and ready to take calls. A configured agent is an agent who has a profile in the system, regardless of their login status. The 2K deployment model also supports up to 4,000 IVR ports, up to 120,000 BHCA, and up to 12,000 concurrent calls1.

There are two types of upgrades available for CCE: Common Ground and Standard. A Common Ground upgrade is a type of upgrade that allows you to upgrade from one major release to another major release without having to rebuild your configuration. A Common Ground upgrade preserves your existing configuration and data, and applies the new features and enhancements of the new release. A Common Ground upgrade is supported for certain releases and deployment models, and requires a specific upgrade path. A Standard upgrade is a type of upgrade that allows you to upgrade from one minor release to another minor release within the same major release. A Standard upgrade also preserves your existing configuration and data, and applies the bug fixes and minor enhancements of the new release. A Standard upgrade is supported for all releases and deployment models, and does not require a specific upgrade path12. References:

SSLUtil is a Cisco-provided utility that helps to configure web servers for use with TLS. It is located in the \icm\bin folder. It can be invoked in standalone mode or automatically as part of setup. It is used to manage IIS certificates on the CCE servers for web applications such as Unified CCE Administration, WebSetup, and ISE. References:

 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.

The CiscoCertUtil tool is a utility that helps you manage certificates on any Contact Center Enterprise machine for machine-to-machine secure communication across components. Some of the functions of the CiscoCertUtil tool are:

• It generates certificate signing requests (CSR) that can be submitted to a certificate authority (CA) for obtaining CA-signed certificates. A CSR is a message sent from an applicant to a CA in order to apply for a digital identity certificate. It usually contains the public key for which the certificate should be issued, identifying information (such as a domain name) and integrity protection (such as a digital signature).
• It generates self-signed certificates in the PFX format, which is a binary format for storing the server certificate, any intermediate certificates, and the private key in one encryptable file. PFX is an acronym for Personal Information Exchange. PFX files are typically used on Windows machines to import and export certificates and private keys.
• It creates a log file pertaining to the operations that it performs for troubleshooting. The log file is located in the \icm\bin\CiscoCertUtil.log folder. The log file contains information such as the date and time of the operation, the command executed, the parameters used, the status of the operation, and any error messages.
• It validates any certificate that is installed on the machine. It checks the validity period, the signature, the trust chain, and the revocation status of the certificate. It also displays the certificate details such as the subject, the issuer, the serial number, the thumbprint, and the public key.

 The URL for the VOS O/S admin page is https:// :8443/osadmin. VOS O/S admin is a web-based tool that allows you to perform various administrative tasks on the Unified CCE servers, such as managing users, certificates, services, network settings, backups, and upgrades. VOS O/S admin requires the fully qualified domain name (FQDN) of the server and the port number 8443 to access the login page. The other options are not valid URLs for the VOS O/S admin page12. References: Cisco Unified Contact Center Enterprise Installation and Upgrade Guide, Release 12.5(1)1, Cisco Unified Contact Center Enterprise Administration Guide, Release 12.5(1)2.

 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.

The correct tools to download logs for CCE troubleshooting are:

• Diagnostic framework portico: This is a web-based interface that allows you to access various diagnostic tools and logs for CCE components. You can use it to run diagnostic tests, collect logs, view system status, and troubleshoot issues1.
• Unified System CLI: This is a command-line interface that allows you to access diagnostic tools and logs for CCE components from a single point of entry. You can use it to run diagnostic tests, collect logs, view system status, and troubleshoot issues2.
• RTTEST: This is a command-line tool that allows you to monitor the real-time status of CCE components and processes. You can use it to view the state of calls, agents, peripherals, routes, and scripts3.

An automated deferred sync job is a process that synchronizes the configuration data between the Unified CCE Administration and the CVP servers. An automated deferred sync job runs on the Principal AW machine, which is the primary Administration and Data Server (ADS) in the Packaged CCE deployment. The Principal AW machine initiates the sync job every 15 minutes by default, or whenever a configuration change is made in the Unified CCE Administration. The sync job sends the configuration data to the CVP servers using the REST API. The sync job also updates the status of the CVP servers in the System and Device Sync page of the Unified CCE Administration12. References:
