Control Center on Cisco Unified Contact Center Express Serviceability Comprehensive and Detailed Explanation: The Control Center on Cisco Unified Contact Center Express Serviceability is a web-based interface that allows you to start, stop, and restart Cisco Unified CCX services. You can also view the status of each service and the server on which it is running. The Control Center is accessible from the Navigation drop-down list on the Cisco Unified CCX Serviceability page.  You can select either Network Services or Feature Services to manage the corresponding services.

 CTI route points are virtual devices that can receive multiple, simultaneous calls for application-controlled redirection. They are added or configured for Cisco Unified Contact Center Express (UCCX) in the Cisco Unified CallManager Device Configuration. This allows UCCX to integrate with Cisco Unified Communications Manager (CUCM) and use the CTI route points as triggers for UCCX scripts. The CTI route points must be associated with the UCCX application user in CUCM and have the correct partition and calling search space settings.  References :  Cisco Unified Contact Center Express Getting Started with Scripts, Release 12.5(1) - Configuring Unified CCX Triggers ,  Cisco Unified Contact Center Express Design Guide, Release 10.0(1) - Deployment Models ,  CTI Port and CTI Route Point - Cisco Community

A contact service queue (CSQ) is a logical grouping of agents that share similar skills. In Cisco Unified Contact Center Express, skills are assigned to CSQs, not to individual agents. Agents are associated with resource groups, which are then mapped to CSQs based on the skills required. This allows the system to route calls to the most appropriate CSQ, and then to the most qualified agent within that CSQ.

The Cisco Unified Communications Sizing Tool is a web-based tool that helps system engineers to size Cisco Unified Communications solutions, including Cisco Unified CCX. The tool can validate various parameters and requirements for a Cisco Unified CCX deployment configuration, such as the number of agents, supervisors, IVR ports, outbound ports, chat sessions, email sessions, and reporting users. However, the tool cannot validate the following options:

The number of silent-monitoring and remote-monitoring sessions. Silent monitoring and remote monitoring are features that allow supervisors to listen to the agent’s calls without being heard by the agent or the caller. The tool does not support sizing for these features, as they depend on the network bandwidth and the codec used for the calls. The tool only provides a formula to estimate the bandwidth requirement for silent monitoring and remote monitoring, based on the number of sessions, the codec, and the packet size. The formula is: Bandwidth (kbps) = Number of sessions x Codec bit rate x (1 + Network overhead).  For example, if there are 10 silent-monitoring sessions using G.711 codec with a bit rate of 64 kbps and a network overhead of 20%, the bandwidth requirement is: Bandwidth (kbps) = 10 x 64 x (1 + 0.2) = 768 kbps 1 .

The number of historical reporting sessions. Historical reporting is a feature that allows users to generate reports on the historical data of the Cisco Unified CCX system, such as agent performance, call statistics, and queue summary. The tool does not support sizing for this feature, as it depends on the number of reporting users, the frequency and complexity of the reports, and the database size.  The tool only provides some guidelines and best practices for historical reporting, such as limiting the number of concurrent reporting users to 10, scheduling the reports during off-peak hours, and purging the historical data regularly 2 .

The number of ASR and TTS ports. ASR (Automatic Speech Recognition) and TTS (Text-To-Speech) are features that enable voice interaction between the callers and the IVR system, using speech recognition and synthesis technologies. The tool does not support sizing for these features, as they are provided by third-party vendors, such as Nuance or LumenVox.  The tool only provides some recommendations and considerations for ASR and TTS integration, such as using MRCPv2 protocol, allocating enough CPU and memory resources, and configuring the network QoS policies 3 .

The customer must purchase 30 outbound IVR ports and 30 agent seats in addition to the 200 Cisco Unified Center Express Premium agent seats. The outbound IVR ports are required to run the outbound IVR campaign, which can make outbound calls to customers and play prerecorded messages or collect customer inputs. The agent seats are required to handle the outbound calls that are transferred to agents based on the customer’s choice or the campaign configuration.  The outbound IVR ports and the agent seats are licensed separately and are not included in the Premium agent seats 1 , page 2-3,  2 , page 4-1.
