I beg to differ. Although the system being used at present adds nearly
10 million numbers each time you add another 'x' prefix (using my
example 020 x yyy zzzz) and yours would add nearly 100 million, the
present system is much easier to implement. Remember, if you're going to
change existing numbers, you have to inform _every_ person what their
new number is going to be - an impossible task to complete with 100%
success. The way BT is proceeding means that you don't have to inform
anyone of the additional numbers since existing lines keep the same
number and only new lines get a new prefix.
