This blog post is the first I am hearing that Qwest, Sprint and Cingular are blocking calls to Iowa, land of the FreeConference call. If you Google 'blocking calls freeconference', you will see many blog posts and articles about it. This headline caught my eye: "FreeConference-Telco Spat a Nonprofit Headache" From Democracy in Action, on March 18, 2007. Granted it is an arbitrage play, but then that is what most of telco is about. Well, that and patent disputes.
