What type of skills will young voip engineers need?

Dan Brown

Marketing Communications Director, Telecommunications Industry Association (TIA)

Today's grads should recognize their credentials reflect something that goes way beyond specific knowledge -- the ability to adaptably learn new things. That is a core skill they should continue to nurture in professional life, hopefully with the support of an employer that also recognizes and appreciates this. In addition, knowledge of how various technology standards work and how they are developed is not usually something learned in a university classroom, but understanding the role they play in creating market opportunities presents a differentiating opportunity. It's important to note, the need to manage and maintain physical infrastructure will never go away, but as more and more of that infrastructure becomes virtualized, software skills and knowledge of remote management systems are skills that will be increasingly in demand.
