CCIE remains the preeminent vendor certification for network professionals.
The CCIE Voice track was announced in 2003, and more than 800 candidates took the beta-test written exam. This figure was a record number for a CCIE track (surpassing all other tracks, including R&S, Service Provider, Security, and so on).
Since then, the CCIE Voice track has grown in popularity: The number of respondents to the Cisco 2006 CCIE Customer Feedback survey intending to certify in the Voice track now equals the number of respondents intending to certify in the R&S and Security tracks. Furthermore, among those already certified, interest in CCIE Voice now outranks interest in all other tracks, including CCIE Security.
