Bio

Technical Lead
CCIE-Collaboration #17137.

I have been working with Cisco Collaboration technologies since 2002. I started my career on CallManager 3.3 and limited applications that came with it back then to see the technology evolve to broad range of Collab applications, messaging, presence, SIP trunking, contact center, etc. My other area of focus is contact center ranging from small UCCX deployments to large enterprise UCCE accounts. My daily job includes the full project life cycle from pre-sales, architecture and design, to implementation and support.

I started to regularly participate on Netpro in April 2005, and I have to admit I got kind of addicted to the forum. I find it most useful in finding design, implementation and support tricks and shortcuts that greatly help me in my daily activities.

My advice to anyone interested in Networking technologies is to read, research, study and enjoy these technologies as the material is infinite.
