best way if pretranslation.. you can do a hot d 12 91800xxxdddd, for a single 800 number.. if you just want a station that will dial 1800 style numbers you can do that with ncos.. but that will not block internal.. if i wanted just 1800 and zero internal.. i would add a tennant, it's pretty simple, when you turn it on all your stations will be tennant one so give trunk group to ten access.. block access ten to ten.. give ten 2 access two one rlb and one trunk group.. then nocs ncos 1 ten 1, after they dial 9 any digits except 1800/866 etc would give a reorder.
