the persons doing the marketing for the BeoCom 5 f***ed it up! Big time!
I agree! By the incredibly silly standard they used, they could have said that the BeoCom 5 is a satellite phone, an IMMARSAT phone, a Skype phone, a Bluetooth Gateway phone, etc., when, by all lights, it is simply a two-line phone... you can just plug any sort of interface box into either or even both lines and then by such a broad definition, it can be anything you want it to be!
But this is silly, because any old phone meets the exact same standard.
Instance: By B&O's standard, my BeoCom 1 is a cellular phone! —because on Line 1 we have a good 'ole phone line and on Line 2 we have an xLink BTTN, so that when any of our mobile phones ring while at home, we can pick up Line 2 and chat from our BeoCom 1 house phones while using our cellphones as the connection medium.
