As part of the ongoing modernization of MIT's telephone infrastructure, Information Systems and Technology (IS&T) is migrating from multiple legacy systems to a modern, unified, cloud-based service. This process will be completed on a rolling timetable.
  • To determine which system you are using see Which System is My Account On? in the section below.
  • To jump to resource articles for each system see Where Do I Go Next? in the section below.
  • In addition, this document provides a brief comparison of the legacy and new systems, help with your voicemail messages on the legacy system, and information about the transition.

What Do I Need to Know About the New BroadSoft System?

  1. You will need to create a Passcode (PIN) to use the phone's Voice Portal menu system.
  2. If your voicemail is stored on the server and accessed through your phone (rather than email) you will also need to set up your voice mailbox by recording your name. Instructions are provided in the KB article MITvoip BroadSoft Cloud Landing Page.
  3. After your transition you can manage your account at voip.mit.edu and your phone and voicemail features at broadsoft.mit.edu.

Access Voicemail Messages on the Sylantro Legacy System

You can listen to messages on the legacy system for 90 days after the transition. If you wish to save some or all of your legacy messages by downloading them, you must complete within 90 days of the transition. See instructions below.
  • Messages stored on the legacy voicemail system will not be transferred to the new system.
  • Messages stored on the legacy voicemail system will be available on the legacy system for 90 days only from the time of your transition to the new system.
  • You can download important messages individually from the legacy system. Instructions are provided below.
  • Or, you may wish to transcribe your messages or play them to record them on an external device.
  • Dial x3-0000, or 617-253-0000 to listen to your old voicemail.
    For assistance, please contact the IS&T Service Desk at x3-1101 or servicedesk@mit.edu.
