So I havn't closely followed the whole number portability thing, so this is a stupid question, but is number portability only presently between mobile networks, or can other numbers be ported.
In particular, say somebody had an 0800 number tied to thier Vodafone cell account, and that somebody was thinking of getting a VoIP number and running an asterisk box, is there some manner in which that 0800 number can be ported to a voip providor (assuming the voip providor can do 0800 numbers of course)?
