Read an Excerpt
Professional certifications have been an important part of the computing industry for many years and will continue to become more important. Many reasons exist for these certifications, but the most popularly cited reason is that of credibility. All other considerations held equal, the certified employee/consultant/job candidate is considered more valuable than one who is not.Goals and Methods
The most important aspect of this book is to provide knowledge and skills in unified communications deploying the Cisco Unified Communications Manager (CUCM) product. Another goal of this book is to assist in the Cisco IP Telephony (CIPT) exam, which is part of the Cisco Certified Voice Professional (CCVP) certification. The methods used in this book are designed to help in both your job and the CCVP CIPT exam. This book provides many questions at the end of each chapter to reinforce the chapter content. Additional test preparation software from companies such as SelfTest Software (http://www.selftestsoftware.com) will give you even more test preparation questions to prepare you for exam success.
One key methodology used in this book is to help you discover the exam topics that you need to review in more depth, to help you fully understand and remember those details, and to help you prove to yourself that you have retained your knowledge of those topics. This book does not try to help you pass by memorization it helps you truly learn and understand the topics. The CIPT exam is one of the foundation topics in the CCVP certification, and the knowledge contained within this book is vitally important to consider yourself a truly skilledUnified Communications (UC) engineer. The book will help you pass the CIPT exam by using the following methods:
Helping you discover which test topics you have not mastered
Providing explanations and information to fill in your knowledge gaps
Providing practice exercises on the topics and the testing process via test questions at the end of each chapter
This book is designed to be both a general CUCM book and a certification preparation book. This book is intended to provide you with the knowledge required to pass the CCVP CIPT exam.
Why should you want to pass the CCVP CIPT exam? The CIPT test is one of the milestones toward getting CCVP certification. The CCVP could mean a raise, promotion, new job, challenge, success, or recognition; ultimately, however, you get to say what it means to you. Certifications demonstrate that you are serious about continuing the learning process and professional development. In technology, it is impossible to remain at the same level as the technology all around you advances. Engineers must continuously retrain themselves; otherwise, they will find themselves with outdated commodity-based skill sets.Strategies for Exam Preparation
The strategy you use for exam preparation might differ from strategies used by others based on skills, knowledge, experience, and finding the recipe that works best for you. If you have attended the CIPT course, you might take a different approach than someone who learned Cisco Unified Communications Manager on the job. Regardless of the strategy you use or the background you have, this book is designed to help you understand the material so that you can pass the exam.How This Book Is Organized
The book covers the following topics:
Chapter 1, "Cisco Unified Communications Manager Architecture," discusses the Architecture and all the components involved. CUCM hardware requirements, operating system, database, signaling, licensing, and database replication are discussed.
Chapter 2, "Deployment Models," covers the deployment models in which CUCM can be used. This chapter introduces the technologies required for the different UC models. The advantages and disadvantages of each deployment model are considered.
Chapter 3, "Installation and Upgrade," discusses the installation and upgrade options of CUCM.
Chapter 4, "Administration," covers the various CUCM administration user interfaces.
Chapter 5, "Initial Configuration Settings," examines the network configuration, Network Time Protocol (NTP), and DHCP configuration options of CUCM. The chapter also covers frequently adjusted CUCM enterprise and service parameters.
Chapter 6, "Managing User Accounts," examines user account configuration in CUCM administration, the Bulk Administration tool (BAT), and the Lightweight Directory Access Protocol (LDAP).
Chapter 7, "Endpoints," covers the various Cisco Unified IP Phones and the features that they support. Third-party Session Initiation Protocol (SIP) endpoint support is covered, in addition to the Cisco IP Phone boot cycle and registration process.
Chapter 8, "Cisco Catalyst Switches," covers the power and voice VLAN requirements of the Cisco IP Phone. The Catalyst switch configurations are examined for both Native IOS and CatOS switches. The Cisco and IEEE power specifications are also covered.
Chapter 9, "CUCM Configuration," examines the configuration options and procedure for inserting an IP phone into the CUCM database. The chapter also covers the hardening of the Cisco IP Phone to mitigate security risks.
Chapter 10, "Configuring Voice Gateways," discusses the configuration of Media Gateway Control Protocol (MGCP) gateways in both CUCM administration and Cisco IOS.
Chapter 11, "Call Routing Components," covers the fundamentals of call routing and a public switched telephone network (PSTN) dial plan. Digit analysis and path selection are achieved through the use of the router pattern, route list, and route group CUCM configuration elements.
Chapter 12, "Digit Manipulation," covers the process of digit manipulation through calling and called-party transformation masks, translation patterns, prefixing digits, and digit discard instructions (DDI).
Chapter 13, "Calling Privileges," covers the process of class of service through the use of partitions and calling search spaces. The chapter also covers time-of-day routing through the use of time periods and time schedules.
Chapter 14, "Call Coverage," covers the topic of call-coverage paths through the use of a hunt pilot, hunt list, and line groups. Call-hunting flow is discussed via the various distribution algorithms supported in CUCM.
Chapter 15, "Media Resources," discusses the media resources supported in and through CUCM. The media resource topics include music on hold (MOH), conference bridges, annunciators, transcoders, and media termination points. Media resource allocation is discussed through the application of CUCM Media Resource Manager (MRM), media resource group list, and media resource groups.
Chapter 16, "User Features," covers various CUCM features, including do not disturb, call park, directed call park, call pickup, hold reversion, intercom, call back, barge, privacy, and IP phone features.
Chapter 17, "Presence-Enabled Speed Dials and Lists," covers presence theory and configuration through the use of presence groups, presence speed dials, and presence calling search spaces.
Chapter 18, "Voice-Mail System Integration," covers the process of integrating Cisco Unity voice mail with Cisco Unified Communications Manager. Topics include voice-mail profiles, voice-mail ports, message waiting indicators, voice-mail call flow, Cisco TAPI service providers (TSP), and voice-mail subscriber creation.
Chapter 19, "Cisco Unified Video Advantage," covers the Cisco Unified Video Advantage camera, software, and video-streaming fundamentals. Topics include the CUCM configuration of video-enabled IP phones, including call admission control (CAC) video requirements.
