I'm just want to clarrify this thing and hope someone can clear this up. I already earned my CCNP.
Cisco website says that the CCNA Voice exam and recommended training are 640-460 IIUC OR 642-436 CVOICE 6.0 / Implementing Cisco IOS Unified Communications (IIUC) OR Cisco Voice Over IP (CVOICE).
But when I checked out the CCVP syllabus, the prerequisites is CCNA Voice. https://learningnetwork.cisco.com/community/certifications/ccvp/syllabus?view=overview
So I could take CVOICE right away and continue with the other 4 exams for the CCVP right? or I have to take 640-460 IIUC 1st?
That is correct. Assuming your CCNP/CCNA are current, once you pass CVOICE, you will have CCNA Voice. CVOICE also counts towards CCVP, so you will have 4 more exams to pass to complete CCVP.
Hope this helps.
