Each year, the federal government's largest buyer of telecommunications services--the US General Services Administration?s Federal Technology Service (FTS)--meets with its user base and industry partners to consider how best, as a group, to address upcoming challenges. For the Tune into Technology Conference keynote presentation, then FTS Commissioner Sandra Bates asked the question, "What should telecommunications users and managers worry about in this new converged world?" Gilbert Miller, a recognized contributor to some of the largest federal government telecommunications procurements over the past two decades, and Henry Levine, a telecommunications lawyer known for representing large private- and public-sector users in the negotiation of telecommunications contracts, tackled the tough answers to that question. The "Convergence Issues That Keep Us Up at Night" sidebar enumerates their top-10 answers. The rest of the article is based on excerpts from this interview, in which Miller and Levine address the basics of convergence and how it will affect the industry.
