If I want to take CVOICE, Is it the pre-requisite is just to have CCNA certification or do I need to have any other certification in 642 series?.And also let me know which book will be good for self preparation and also the pass percentage. And also let me know whether there will be only theoritical or there will be some configurations that we need to do in the exam.
CCNA is the prereq for Cisco voice certifications except CCIE, which can be taken without a current cert.
I would reccommend IP Telephony Self Study for the CVOICE track - there is a new version said to be released in the next month or two from Cisco Press. The old ISBN is 1-58705-050-1, not sure of the new one.
