Techdirt:Does A Mobile To VoIP Bridge Break Any Laws?
Sometimes one needs to be older to remember things like calling cards and dial around numbers from MCI and Sprint. I don't see any difference bridging to a VoIP line from a cell phone, to call international today, than it was to dial one of the "alternative" carriers back in the 70's and 80's from a mobile or cell phone (80's) to make a long distance call after dialing into an 800 number.
Like they say, history always repeats, but it would be funny if Sprint decided that the action was illegal after all these years.
