If a second number, maybe it makes sense...
Why isn't the bandwidth shared per account? There is no line...this is old pots thinking where additional wires are installed for a second line! UGH
Actually, second line is the proper terminology if you expect both numbers/lines to be able to be used simultaneously. Two physical lines from the ATA to two different telephones are required for this to work. A second (or third, or fourth, or ...) telephone number can be assigned to a single telephone line, but you will not be able to use each number independently and simultaneously.
