It would be within the tariff to allow the residences to have
residential rates, while the rest of the campus pays business rates.
It may not be within the capabilities of the PBX to separate the
outgoing call traffic into different outgoing trunk groups.  NJ Bell
even tariffs residence centrex rates, specifically for the college
dorm customer.

It may or may not be the fault of the PBX.  The facts are that NJ Bell
offers answer supervision, in the form of a loop current reversal, on
PBX trunks.  The service is tariffed.  There is a per-trunk,
per-month, charge for this service.  Assuming that Definity is able to
receive and process this signaling, there is no technical reason why
it isn't being used.  There may, however, be a business reason.
Supervision is charged-for.  You'd pay more for the service.  The
trade-off is between paying more for calls that are chargeable and
paying less, but paying it for some calls which should not have been
charged.

It's not a question of being nice.  It's a question of they offer it
under tariff, and the customer decides whether or not to buy it.
