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).
