very simple, who owns and controls that phone number. in a rolm you build every exten soft, set the forwards hunts, all attribs.then you put that exten on sets. in a nortel, 333 can be key 0 on 31 phones, if 29 people leave and all forward to a diff person where does the call go? it goes to the forward target of the phone that has the marp for 333.. with marp turned off it goes to disney land. or nowhere or everwhere.. thats why i always have marp on
