500-444 Sample Questions & Answers

After successfully running the Integration Wizard on the primary (Side A) Administration & Data Server, the immediate next step is to run the same wizard on the secondary (Side B) server. This process uses the configuration from the primary to set up the secondary components, establish the database replication for the Logger and HDS, and ensure high availability.

The System Inventory page, accessible via the CCE Administration (formerly Web Administration) tool, is specifically designed for this purpose. It provides a detailed checklist of all prerequisite configuration tasks and validates them against the system, showing a status of 'Complete', 'Incomplete', or 'Warning'. This allows administrators to track their progress and ensure all foundational requirements are met before proceeding with the main deployment and configuration.

This is the first step. The call is placed in the queue for the specialized nurse skill group. A timeout value of 90 seconds is configured directly in this node. If an agent becomes available within this time, the call is routed. If not, the script proceeds from the node's failure/timeout output terminal.

Following the timeout path from the Queue node, a Set Variable node is used to modify the call's priority. This is typically done by using a formula like Call.QueuePriority = Call.QueuePriority + 1 to elevate its importance in the next queue.

After the priority is elevated, the call is sent to another Queue to Skill Group node, this time targeting the general overflow queue. The call now enters this new queue with its higher priority.

After creating a trustpoint (crypto pki trustpoint ), you must authenticate it by importing the CA certificate. The crypto pki authenticate command initiates this process. You would then paste the Base64 encoded certificate into the terminal.

In Precision Routing, every Attribute must be explicitly associated with one or more Media Routing Domains (MRDs). If an attribute is created but not linked to the MRD that is handling the voice calls, the routing engine will not be able to use that attribute for agent selection for those calls. This is a common oversight when adding new attributes to an existing system.

In a SIP interaction, an INVITE is sent to establish a call. If the caller hangs up before the call is answered, the calling endpoint sends a CANCEL request. The receiving endpoint (in this case, CVP/VXML Gateway) responds to the original INVITE with a '487 Request Terminated' to acknowledge that the call setup was cancelled by the originator. Therefore, seeing many 487 messages in CVP logs for queued calls is a strong indicator of caller abandonment.

This is the most common and comprehensive deployment model for PCCE, utilizing CVP for queuing and self-service, and Unified CM for agent endpoints and call control.

This model is used for deployments where only intelligent network routing is required, without local agents. It's a smaller footprint deployment that leverages ICM for network-level routing decisions without the full agent-facing components.

This is the Cisco-supported and recommended design for geographically separated PCCE deployments. The native ICM replication mechanism is designed to handle WAN latency for the Logger's real-time data. SQL Always On is not supported for stretching the Logger database across a high-latency WAN. For historical data, the supported method is to have a separate HDS in each data center, with each HDS receiving data from its local Logger. This prevents historical data replication from impacting real-time call processing and aligns with the standard PCCE redundancy model.

The Network VRU Timeout value is the amount of time, in seconds, that the ICM Router waits for an acknowledgment or response from the VRU Peripheral Gateway (like the CVP PG) after sending it a message (e.g., a 'Run Script' request). If no response is received within this time, the Router assumes the VRU is out of service and will execute the error path in the script.

False. Enterprise Chat and Email (ECE) is a separate solution that requires its own dedicated servers. It is not installed on any of the core PCCE or CVP virtual machines. It integrates with PCCE but has its own distinct architecture and installation process.
