Last number redial
At Indiana University Bloomington and IUPUI, the Last Number Redial feature of your on-campus telephone service allows you to redial the last number you dialed. (This feature is available only for M5112, M5312, and M5316 business sets.) To activate this feature, press ##.
Note: When activating Last Number Redial on a long distance number, you will need to redial your Authorization Code when you hear the "stutter" dial tone. The code is not stored in the number sequence.
