This article describes how to make calls to on-campus phone numbers, off-campus phone numbers, long distance phone numbers, etc.

Before You Begin

Making calls from a campus telephone is somewhat different from using a home phone or mobile phone. Follow the instructions below to learn how to make a variety of calls from an on campus phone.

Making an On-Campus Call

To make an on-campus call, do the following:

  1. Pick up the handset.
  2. Do one of the following:
  • To call an office phone number, dial 8 followed by the four-digit phone number.
  • To call a residence hall phone number, dial 6 followed by the four-digit phone number.

Making an Off-Campus Call

To make an off-campus call, do the following:

  1. Pick up the handset.
  2. Dial 7 followed by the seven-digit phone number.

Making a Toll-Free Call

You can call 800, 877, and 888 numbers toll free. To make a toll-free call, do the following:

  1. Pick up the handset.
  2. Dial 7 + 1 + the ten-digit toll free phone number.
