Centrex is a service provided by your local phone company, sometimes under
various service marks; here in New Jersey, we have a Centrex service called
CustoPak, which is a service mark of Verizon. Regardless of the name, there
are several things about Centrex you should understand before buying phones
to use with Centrex services.
Centrex is a service originally intended to provide multi-location businesses
with the ability to tie their locations together as though (from a telephone
standpoint) they were in one location. Universities with large campuses (and
multiple campuses), chain stores, and other multi-location organizations have
benefited from Centrex.
The big benefit is that phones in the same Centrex group can put callers on
hold, transfer calls to other phones in the organization, hold conference calls
across multiple locations, even page from one location to another (with appropriate
paging hardware).
