    One phone number != one phone line.

    Each phone circuit has a single associated billing/account number. Notice I
    say circuit, not line, which is 1 or more channels over some medium. It may
    be a single line POTS, a 2 channel ISDN, a 23/24 channel T1, a 600+ channel
    T3, etc. In addition to the account number, one or more additional phone
    numbers can be directed at that account or agroup of accounts, either as a
    direct routing to a particular channel(s) or a roll-over between groups of
    various accounts. A call to a phone number is therefore is directed at a
    particular account number which, if all channels are busy, may roll on to
    other account numbers in the group.
