A Guide for Cisco Voice Certification – CCNA Voice 640-460 or CVoice 642-436
In this article I want to mention about a popular question of Cisco Voice Certification System. Should you go with CCNA Voice 640-460 or CVoice 642-436? It is also the most asked question in this site so now I am happy to answer it with all the information I know in a separate article. If you know anything more, please don’t hesitate to comment!
First you should learn about the difference between them. The CCNA Voice 640-460 exam, sometimes called the Implementing Cisco IOS Unified Communications (IIUC) 640-460 exam, is the exam for those who are working with the Cisco CallManager Express (CME), Cisco Unity Express (CUE), Unified Communications 500 (UC500) Smart Business Communications System solutions and implementing EPhone, IP Phone. These devices are often used in medium & small organizations (with less than 2000 employees).
In the other hand, the CVoice 6.0 642-436 exam is dedicated for ones who use the Cisco Unified Communications Manager (CUCM) and Cisco Gateways/Gatekeepers, including dial-peer & call-leg concept, H.323 & SIP protocols. It is typically employed by large organizations such as governments, large companies. In general, this path is easier to learn than the previous path and it is similar to CCNA and CCNP with command-line-interface (CLI). Moreover, you can use GNS3 to simulate a Voice Gateway or Gatekeeper so you will have more fun (in the case you don’t have real devices).
