Candidates who were interested in taking the 9E0-422 IP Telephony Troubleshooting exam must now take the 642-424 IPTT exam. The 9E0-422 test contained up to 65 questions and required 75 minutes to complete. Candidates registered for the exam through Pearson VUE or Prometric. The exam was designed to validate a SE's knowledge and skills in troubleshooting CallManager, Unity, and IP network deployments. The IP Telephony Troubleshooting (IPTT) training course was recommended for anyone attempting to complete the exam. Authorized Certified Cisco Instructors provided the training.
Throughout the 9E0-422 exam, candidates were required to prove their ability to identify voice network troubleshooting issues and tools. Candidates were also required to prove that they could identify network infrastructure troubleshooting issues and the complexities of troubleshooting voice networks. Successful participants were expected to demonstrate an understanding of the symptoms involved in network problems while also being able to identify solutions. Signaling architecture, dial plan and routing troubleshooting, 911 implementation, utilities troubleshooting, database tools, and the Cisco Integrated Communications System 7750 were additional concepts included on the test.
The Real Deal
I will confess that I tried a few other cheaper sites before I tried TestsForge. As the saying goes, you get what you pay for! Their information was really outdated, and poor quality, I regretted my choice right away. Unfortunately it was money wasted as they didn't offer a money-back guarantee. That is how I found TestsForge.com. They really know what they are doing, their examples were spot on for the actual test. They offer the money back guarantee because they know you won't need it, they are that good. Thanks again for helping me succeed on the Cisco 9E0-422: IPTT.

Cisco 9E0-422 Assistance
My job required I get a certificate in routers. I began studying the materials I had gathered. There were so many pages to study that I spent all my time reading. I knew there had to be an easier way to study so I searched the Internet. I found this site with more than just my information, but so many other vendors. I couldn't believe my luck so I ordered the for the Cisco 9E0-422: IPTT exam study materials. When I got the study packet, I knew immediately that I had made the right choice. The pack had test questions showing me exactly what I needed to know. I passed the exam much to my employer's satisfaction. Thanks so much for the help!
