(1) act on the format, content, code, protocol or similar aspects
of transmitted information;
(2) provide additional or restructured information; or
(3) involve subscriber interaction with stored data.
Enhanced 800 Service may include dynamic call routing based

translated to one-or-more POTS numbers or trunk groups. In some
cases, duplicate 800 numbers may be assigned in different USA

800 Portability
Original 800 service used the exchange (NXX) to specify the
carrier. This made it impossible to keep the same 800 phone number
when changing carriers (long distance company). On May 1, 1993,
FCC mandated that 800 Service subscribers
can keep their numbers when they change carriers and that they can
divide their traffic among carriers (by time of day, location, etc.)
This has complicated the process of making changes. (See NASC, RespOrg and
SMS)
