Centrex Lines:

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. 

In 2007, the Centrex contract formerly held by Verizon was awarded to Level 3 Communications.  During 2008, the state's phone lines will be migrated to Level 3 from Verizon in a gradual process by location.  DII Telecommunications and Level 3 are working to minimize disruption of state business when a site is impacted by the migration.

Analog phones:

This type of phone is the most common standard-issue for most state employees answering a single line at their desk.  There are also analog phones capable of answering two, three and four lines if circumstances require this capability.

ISDN phones:

These are commonly used at high volume attendant or receptionist positions where multiple line appearances are required.    User guides for some of the ISDN phones the state uses are listed below.
