Beginning to pursue the CCIE Voice written exam can be daunting. But, I feel it's best approached as an extension of the Cisco CCVP certification. Much of the suggested reading for the CCVP forms the groundwork for the CCIE Voice Written.
The CCVP certification covers Cisco Voice over IP, QoS Principles, and Implementing and Troubleshooting Cisco Unified Communications Systems. Personally, I found that the CCVP gave me a nice introduction - but it did not provide me all that I needed to know in order to competently support Cisco Unified Communications system. For me, there was no substitute for experience.
That said, the CCVP also did not prepare me to pass the CCIE Voice Written exam. The CCIE Voice Written exam requires a much deeper understanding of the CCVP topics - plus many more topics that are not covered within the CCVP - see the blueprint below. In fact, the first time I took the CCIE Voice Written (I passed on my second attempt) - I was really caught off guard at the shear scope of the topics you will need to know for the CCIE Voice written.
Don't make the same mistake - make sure you're prepared!
