戴夫·舒尔茨本周在博客中顶替温德尔。戴夫已经参与了网络和安全超过24年。在中西部地区经销商合作，他的经验已在安装/支持变化，对于一个企业的数据中心咨询和管理承包。雷竞技电脑网站目前，戴维教授的声音技术的天际线先进的技术服务。Dave拥有CCNP，CCDP和CCVP认证。
现在，你有学习和良好的基本依据走上一个愿望是你旅途中，我们需要把我们的第一个步骤。伴随着良好的学习习惯，学习技术，这是可取的，你开始采取在其网站上看看的CCVP（思科认证语音专家）思科职业认证的位置你的旅程。看到：
(http://www.cisco.com/web/learning/le3/le2/le37/le65/learning_certification_type_home.html）。
你会发现在这个网站，思科提出了一些导致的CCVP认证课程和测试。无论您希望获得此认证，或者只是希望获得的知识，这是可取的，你专注于这些特定教材的研究工作。这将确保你很好地覆盖在所有的基本技术概念，留下你的知识基础没有间隙。
If you currently have a background in networking, I suggest that you start with the CVOICE path (642-432). The training can be achieved through a number of different methods. First, you can purchase the CVOICE book from CiscoPress (http://www.ciscopress.com/）。这将为您提供语音技术的坚实基础，也适用于不仅是路由器，但Cisco CallManager的。而且，我在我的第一篇文章中提到的，你需要知道的技术，什么命令都在做，而不是仅仅知道该类型的命令。然后，我会建议参加教师指导的CVOICE当然前提思科授权培训合作伙伴。天际线先进的技术服务托管在美国（在各个城市，这些和其他所有的思科课程查看我们的网站上http://www.skyline-ats.com/）。Instructor-led training is not only a good start to learning the technology, but will help "fill in the gaps" of your understanding, and works to clarify all aspects of voice technology through lectures, discussions and lab exercises. Also, the course guides that you receive are great reference materials in your arsenal. One of the main reasons to attend instructor-led training is the invaluable hands-on experience you will gain by working on equipment in a non-production environment. In an instructor-led course, you are able to interact with peers, ask question and gain invaluable knowledge that you would not normally get through reading a book or personal study. Of course, personal study/reading, along with instructor-led training is like a well-balanced meal. You really need both to help build a complete understanding.
Once your complete the required courseware, you should be well-prepared to take the Cisco certification exam for that specific courseware (scheduled through Vue athttp://www.vue.com/), if so desired.
其次，我建议跟进这一类服用CIPT（思科IP电话）课程。你需要决定你想了解哪些特定的操作系统，无论是CallManager的（版本4.x或5.x的）。请记住，CallManager的4.x版是基于Windows Server平台，其中CallManager的5.x版是基于Linux平台上。我认为这里的资源将是读叫CiscoPress书，配置Cisco CallManager和统一：有步骤，分步指南，由Dave贝特曼。这本书目前仅适用于CallManager的4.x版。然后，你应该计划出席CIPT1和CIPT2课程（也由天际线提供），因为我提的CVOICE课件同样的原因。这两个课程将不仅为你准备的CIPT考试（642-444 4.1版本），或者，（642-445为第5版），但为您提供了IP电话的坚实基础，以及CallManager的的工作知识。
The other courses mentioned on the Cisco Career & Certifications site will build on this technology. Troubleshooting Cisco Unified Communications Systems (TUC), with exam 642-426, will build a deeper understand of CallManager and Unity, from the perspective of troubleshooting and knowing how to use the specific tools integrated within CallManager. The Implementing Cisco Voice Gateways and Gatekeepers (GWGK) course, with exam 642-453, will also build on your understanding of gateways and gatekeepers that you previously learned within the CIPT courseware. Finally, the Quality of Service (642-642) courseware will provide you with an understanding to manage the quality of service within your existing network, since it is important to optimize the given bandwidth before implementing IP telephony. The best resource I would suggest here for QoS, along with the instructor-led training, is to purchase the Quality of Service book (CiscoPress) book written by our host of this article, Wendell Odom.
最后,你的学习resources should also contain two necessary items. The first item is the Solution Reference Network Design (SRND) for CallManager. Cisco makes these available on their web-site, and, has provided these for every technology and product that they support. The CallManager SRNDs' are over 900 pages of design information, technology and product information that will accelerate your learning, and help build your understanding on CallManager. The second resource is the Cisco DocCD (www.cisco.com/univercd) that provides all configuration information on CallManager. Also, if you are planning to go on to CCIE (Cisco Certified Internetwork Expert) certification, this is the only documentation that you are allowed to use during the lab exam.
In the next installment in this series, I will address the learning of voice technology for those that may not have a networking background, and also, address the questions and replies to the past articles. So, feel free to send your questions and thoughts and I'll do my best to help set you on the path of breaking into the world of IP Telephony.
