The reason it matters is if there isn't already a media converter installed outside then VM will install it wherever they want, which is the easiest place for them rather than where the OP wants it. They won't tell the OP when the external install is being done either.
What is a "media converter" please? How big is it (ooer matron)? I am just getting the phone and broadband.
