Centrex Service:

The state has a very cost effective contract for telephone service which is known as "Centrex".  Centrex allows all state callers in the same locality to call other state offices in that locality by dialing only the last four digits of the telephone number. These calls are free and save the cost of local message units. Telecommunications can request that voice mail be provided on any state Centrex line. 

Centrex Features
