Muhammad Ashar, CCIE #26244
I passed my CCIE Voice exam last year and INE material did help me a lot in getting my foundation right. I used INE workbooks to prepare for my CCIE with couple of other vendors as well. They workbooks very quite informative and did the trick of explaining the concept. I still remember I use to go through several posts on INE Voice blog to get a better understanding of a topic. All in all, INE helped me in getting my CCIE.
