On June 24th, 2009, Learning@Cisco announced program changes to the CCNA Voice certification. There are now two options available for candidates wishing to achieve their CCNA Voice certification: A commercial option and an enterprise option.
The new CCNA Voice Certification enterprise option assesses skills/knowledge related to the Cisco Unified Communications Manager 6.0 (CUCM 6.0). It is typically employed by large organizations such as governments, large companies, and colleges. Passing the CVOICE #642-436 exam will meet the requirements for this option.
The CCNA Voice Certification commercial option continues to use the IIUC #640-460 exam and assesses skills and knowledge related to the Cisco Unified Communications Manager Express 4.1 (Cisco UME) and Cisco Unity Express (CUE), solutions typically used by medium & small organizations such as companies with less than 2,000 employees, retail businesses, and small school districts.
