Telephone Service

Telephone service at MSU is provided by a privatized, digital Nortel DMS-100 Centrex telephone switch. The switch provides dial-tone for approximately 14,000 administrative telephone numbers and approximately 11,300 student telephone numbers that have a 517 area code and one of the four prefixes 353, 355, 432 or 884.

Administrative users must contact us for service and student users must contact University Housing for any telephone-related concerns.

Departments can choose to connect to MSU telephone service in two ways. The first method is to connect each telephone number directly to a single telephone instrument located in an office or lab. The second, and more complex method, is to connect each telephone number to a departmental or building-wide telephone system. In this scenario, each user has a proprietary telephone instrument in their office or lab that connects to this centralized system for telephone number access and other advanced features.

Each administrative telephone number can provide faculty and staff with a standard set of digital Centrex features including 5-digit dialing, campus transfer, three-way calling, and caller ID. Each telephone number also allows the greater campus community to access the University Operators, campus voice mail, long distance, and automatic call distribution (ACD), among other features.

Consulting and analysis service is available to help you identify the telephone system and service option that best meets your individual or departmental requirements.
