Dean Bubley’s view point on Fixed Mobile Convergence is one I have been following closely for the past few years. His recent post on FMC and how it relates to the Enterprise is one for the books and needs a read.
Dean points out that the favorable bucket of minutes in the USA and the lack of distinction between mobile and landline numbers here encourages FMC, while in other parts of the world is an impediment because of the expense of calling a mobile phone from a landline or inter-carrier calling.
