A system and method for numbering plan area (NPA) split processing is
disclosed. In one implementation, a query is received during a permissive
dialing period. The query comprises a destination location that is
associated with a first NPA. It is determined whether a first call
processing record identifies a service that is NPA sensitive. The first
call processing record is associated with a destination location that is
undergoing a NPA split. The first call processing record is identified by
the destination location and the destination location is associated with
a first NPA. A second call processing record is then used for processing
in place of the first call processing record when the first call
processing record identifies a service that is NPA sensitive. The second
call processing record is associated with the destination location that
is undergoing an NPA split. The second call processing record is
identified by the destination location and the destination location is
associated with a second NPA.
