 The Cisco Unified CCX license MAC is generated based on the hostname, IP address, and gateway address of the Unified CCX server. These are some of the system parameters that affect the license MAC, which is different from the physical MAC address of the system. Changing any of these parameters can invalidate the current license files. The Cisco Unified CCX version and the physical MAC are not used to generate the license MAC. References := Cisco Unified Contact Center Express Installation and Upgrade Guide, Release 12.5(1), Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 Course Outline

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 kbps1.
• 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 regularly2.
• 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 policies3.

 In a typical Cisco Unified CCX agent web chat deployment for an online retail shop, Cisco SocialMiner can be deployed in the demilitarized zone (DMZ). The DMZ is a network segment that lies between the Internet and the corporate network, and it provides a layer of security and isolation for the servers that are exposed to the public. Cisco SocialMiner is a server that enables social media customer care by capturing and routing social contacts from various sources, such as web chat, email, Twitter, and Facebook. By deploying Cisco SocialMiner in the DMZ, the online retail shop can offer web chat services to its customers without exposing the Cisco Unified CCX server or the agent desktops to the Internet. Cisco SocialMiner acts as a proxy between the web chat clients and the Cisco Unified CCX server, and it communicates with the Cisco Unified CCX server using a secure HTTPS connection. The web chat clients can access Cisco SocialMiner using a public URL, and Cisco SocialMiner can also access external social media sources if needed. References: Deploying Cisco Unified Contact Center Express (UCCXD) v6.0 - Module 2:Implement a Cisco Unified Contact Center Express System - Lesson 2: Implement Cisco Unified CCX Web Chat - Topic: Cisco Unified CCX Web Chat Deployment Model

The correct answer is C. Only agent phones that are used with the Cisco Finesse agent desktop must be associated to the RmCm application user account. The RmCm application user account is a special user account that is created by Cisco Unified Contact Center Express (UCCX) during the initial setup and is used to control and monitor the agent phones through the Computer Telephony Integration (CTI) interface. The RmCm application user account must have the Standard CTI Enabled and Standard CTI Allow Control of Phones supporting Connected Xfer and conf user roles, and must have the agent phones associated as controlled devices. This allows the UCCX to perform actions such as logging in and out agents, changing agent states, making and receiving calls, transferring and conferencing calls, and sending and receiving enterprise data1.

The other options are not correct because:

• A. All phones must be associated to the RmCm application user account. This is false because not all phones need to be controlled and monitored by UCCX. Only the phones that are used by the agents who log in to the Cisco Finesse agent desktop need to be associated to the RmCm application user account. Other phones, such as supervisor phones, IVR phones, or non-UCCX phones, do not need to be associated to the RmCm application user account2.
• B. None, because that user account is not used for phone association. This is false because the RmCm application user account is used for phone association. The RmCm applicationuser account is the user account that UCCX uses to communicate with the Cisco Unified Communications Manager (CUCM) and control the agent phones. Without phone association, the RmCm application user account cannot perform the CTI functions that are required for the UCCX features1.
• D. Only Cisco Finesse IPPA phones must be associated to the RmCm application user account. This is false because Cisco Finesse IPPA phones are not supported by UCCX. Cisco Finesse IPPA is a feature that allows agents to use the Cisco IP Phone Agent (IPPA) service to log in to the Cisco Finesse server and access the Cisco Finesse agent desktop features. However, this feature is only available for Cisco Unified Contact Center Enterprise (UCCE), not for UCCX. UCCX agents can only use the Cisco Finesse agent desktop web interface or the Cisco Agent Desktop (CAD) application to log in and access the UCCX features3.
