I am a voice engineer and have been working on IP Telephony since 2004. My plan is to take the CVoice, CIPT 1 & 2, and TUC exams, to get them out of the way and then do CCNA and QoS to complete the CCVP requirements. My question is, once I pass the CVoice exam how long do I have to complete CIPT 1 & 2, TUC, CCNA & Qos? Do I have 3 years to have all of them completed in order to become CCVP certified or is the time shorter? Also, is the CVoice the exam that is taken to satisfy the CCNA Voice Certification or is there a CCNA Voice exam? Any info would help.
