On campus calls are four-digit dials called a "Local". To dial external numbers, first dial 9.
If you press 7* on a campus phone you will be able to access voice mail. You can also access the voice mailbox from other campus phones by pressing 7*, waiting for the attendant, then press **. Additionally, you can access your voice mail from off campus by calling your full ten digit number, and when the greeting starts press the * key. The system will then ask for your password.
Voicemail Instructions can be found in the IT Services Knowledge Base: Voicemail Instructions. Review the PDF attached to this linked article.
