IU UniCom feature comparison

On this page:


Office telephone service for faculty and staff at Indiana University will begin to transition from Skype for Business to Microsoft Teams at IU in the first quarter of 2023. UITS encourages all students, faculty, and staff to switch from Skype for Business to Teams for chat now. Faculty and staff should continue to use Skype for Business for external phone calls until notified that their account has been moved to Teams Calls. For more, see About Microsoft Teams Calls at IU.

For Indiana University's UniCom service, the features you can use depend on your configuration, as well as on what equipment and software you have. The main differences between the configurations relate to the connection between your phone line and the phone features available through UniCom:

  • In UniCom Basic, your office phone line and the UniCom phone capability operate independently of each other, so UniCom calls and regular calls function differently. Students may use UniCom Basic, since no phone number is associated with UniCom calls.
  • In UniCom Enterprise Voice, your phone line is routed through UniCom, allowing integration between phone and computer features. UniCom Enterprise Voice includes all the features of UniCom Basic. Only faculty and staff are eligible for Enterprise Voice.

See the table below for detailed descriptions.

In UniCom Enterprise Voice, you can only associate one phone line with UniCom. If you have multiple phone lines, you may want to discuss your situation with IU Telecommunications to determine what configuration is best for you. Call 812-856-2287 (IUB) or 317-274-3004 (IUPUI).

To change your UniCom mode, fill out the UITS Telecommunications Request form.
