UCaaS - It's Not Your Grandfather's Centrex
Back in 2003, I wrote a client-sponsored piece called, "Hosted Services-It's Not Your Father's Centrex," that was published in the ACUTA Journal of Communications Technology in Higher Education, Winter 2003 issue. For some reason, it was one of the few available analyses of the trade-offs between premises and hosted VoIP alternatives and I received inquiries about it for years (as late as 2011) from everywhere from Australia to Africa.
