IP to outsell traditional PBX this year

I'm keynoting an event next week for a group of IT executives/CIO's of major companies, in participation with Nortel. While preparing, I came across this stunning statistic -- "2003 will be the year when IP station shipments first exceed traditional private-branch-exchange (PBX) stations. " (Source: In-Stat MDR) In other words, the global telephony network is migrating to an Internet-type backbone quicker than you might think. This bears huge implications for the future, in terms of workspace, the future of the office, the way we communicate, and countless other major trends. It's something I've been talking about for years.
