These aren't calls using a prepaid card, but the LEC issued post paid
calling card (shows on your local home phone bill). The calls are
originating in South Carolina but are arriving with Caller ID of the
Calling Card, which has a Toronto Ontario (416) phone number.
Perviously these arrived as "Private Number" or occasionally "Out Of
Area/Unknown". Now the phone number to which the call is billed is
arriving as Called ID!
