I cleared my CCNA Voice today.
Thanks to everybody in CCNA VOICE GROUP lot for their support. Special regards to Martin.
I took 6 months along with my job. Got bit delayed due to some reasons.
My references: Cisco Press CCNA Voice book.CBT Nuggets(new one)
CCNA is tougher that CCNA voice, as it includes complete basics on all concepts of networking. CCNA voice focuses mainly on telephone stystem.
