Objectives of the Exam:

The exam aims to test the candidate's knowledge and skills in implementing and defining centralized call processing. They have to configure or describe fail-over device, survivability call, Remote Site Telephony and Fallback Operations. In this exam it will demonstrate how the Call Admission controls and bandwidth management have to be executed when necessary. The examinees need to classify the purposes of gatekeeper and configure alternate routing, locations and regions. Their strategic skills are assessed in implementing RSVPs, MTPs and transcoders. They have to define issues with multi-site dial plans and globalized call routes as well as to execute numbering plan for multi-sites.

  1. Implementing Mobility Features covers configuring Mobility on Cisco Extension and Unified Communications Manager Devices.
    • Among the configurations to consider are the following; Multi-site Music On-Hold, Locations and Automated Pass4sure 642-457 alternate routing
  2. Describing and Implementing centralized call processing redundancy defines the device fail-over, differentiates trunk types and gateways supported by Cisco Unified Communication Manager, globalized call routing, and multi-site dial plans. It aims to implement MTPs, transcoders and trunks as it verifies redundancy operations in the process.
  3. Implementing Cisco Inter-Company Media Exchange and call control discovery
    • Configuring service advertisement frameworks such as call control discovery, client control and forwarder.
    • Configuring regions, call survivability, MGCP fallback operations and tail-end hop offs
    • Configuring Cisco unified communications manager to allow redundancy
    • Configuring Cisco unified survivable remote areas telephony operations
  4. Call Admission Control and Implementing bandwidth management
    • Define gatekeeper functions
    • Implement gatekeeper-based admission controls, SIP Preconditions and RSVP Agents
  5. Identify the dial-plan requirements for SRST and MGCP Fallback by using CUCMs as an option
  6. Identify the function of MGCP Fallback
  7. Identify the function of Cisco Unified SRST
  8. Identify the SRST features, protocol supports and versions that are necessary for the release of Cisco's IOS Software
  9. Determine the basic functions of Cisco unified SRST on how it enables the routers to backup Cisco Unified IP Phones with connection failure when WAN is down or when CUCM servers do not function.
  10. Describe the function of CUCM Express for Cisco Unified SRST and the wider features it offers such as the Cisco Extension Mobility, Presence, CallPark, and Cisco Unity Voice Messaging Access

Meanwhile, CCNP Voice verifies expanded skills and comprehension necessary to converge into the basic networking architectures. Moreover, it provides the most substantial capabilities to implement, troubleshoot, configure and operate integrated IP Networks. It emphasize on Cisco Unified Communications Manager / CallManager QoS or quality of service, IP phones, gatekeepers, gateways, voice applications and Cisco utilities such as Catalyst Switches and Routers. The troubleshooting and integration of Cisco Unified Communication Applications are likewise included in the CCNP Voice particularly the Cisco Unified Presence and Cisco Unity Connection Applications.

Career Prospects:

A Cisco affiliated Professional have the ample opportunities in the globally competitive IT Industry. Every organization seeks highly competitive individuals to fulfill certain specific job roles. It is a common knowledge that Cisco is one of the leading providers of certified outstanding professionals in various fields in Information Technology. For that reason, the Cisco 642-457 ensures profitable careers as Communications Technician, Communications Specialist or a Cisco Unified Communications Manager.
