Dialing Instructions

Campus, Local, & Long Distance Dialing

The RIT telephone system provides direct inward dialing, direct outward dialing and dialing among telephones within the system.

Callers have several options to connect with faculty, staff and students. From off campus, they can either dial the person's direct number. From on campus, the individual department or person can be reached directly by dialing their 5 digit extension number. A campus directory of faculty, staff and departments is available on line and in print form through ITS Communications Services.

For further assistance, call ITS The Service Desk at x5-5800 (V\TTY).
