Call Forwarding
Forwarding to an On-campus Phone

needs dictate. You can forward incoming calls to another MIT phone number, including the voice mail system if you are a subscriber.
For details on call forwarding for voice mail, see the
User's Guide to the MIT Voice Mail System
(TC-1).
Call Forwarding Conditions (On Campus)
The following table described the call forwarding conditions and gives the codes to activate and cancel each one. You can have any
combination of call forwarding conditions active at one time; however, forwarding of all calls supersedes any other active forwarding.
