About Me


You can see my full LinkedIn profile above if you are really interested, but over the years I've had a variety of network and telephony experience with products by companies such as Cisco, Lucent, Avaya, Microsoft, Adtran, Nortel, etc.

I originally started this blog several years ago as a way to easily keep track of efforts to study for Cisco's CCIE Voice exam.  I figured that if I found something I knew that I'd need to use again later - I could find it on my blog.  As it turns out, there are a few other people that can use it as well and it's turned into what you find today.

Am I a CCIE?  No.  I've passed the CCIE Voice written a couple of times along the way.   However, I've taken one attempt at the CCIE Voice lab and failed - but that was a great learning experience and really clarified how to prepare for it.  It's not out of reach, but it does take dedication and commitment.  I currently hold the CCNP Collaboration certification and a variety of related specializations.

I try my best to use what I learn along the way to enhance this Cisco voice certification blog with information that will most benefit CCNA Voice, CCNP Voice and CCIE Voice (CCIE Collaboration) students.
