Virtual Voice Mail Referral Lines for Faculty

The online telephone directory lookup contains location and title only for those who have a telephone extension number.  Most faculty members, for example, do not have a campus extension or phone, so Telecommunications has broadened the use of the voice referral line.

By redesigning the voice referral line option, the new Voice Mail Referral line is a virtual line that will give any employee a campus number that goes straight to voice mail when dialed. When the caller leaves a message, it will be routed to the employee’s email inbox as an email containing a WAV file attachment of the message and a transcription.

This line type allows the employee to have a more substantial campus presence.
