Get started with UniCom/Skype for Business or Microsoft Teams at IU

Eligibility and account types

At Indiana University, the UniCom service provides unified communications via the Microsoft Skype for Business clients. Phone service for faculty and staff is provided by UniCom Enterprise Voice. Students, as well as faculty and staff members with no IU phone number, may use UniCom Basic, which operates independently of a phone number.

For more about the features of the two different modes, see IU UniCom feature comparison.

When you sign the Emergency 911 statement (see below), you automatically get a UniCom Basic account. To change your service, contact your department's telecommunications coordinator or IT Pro.

If you do not know who your telecommunications coordinator is, at IU Bloomington, call 812-856-2287; at IUPUI, call 317-274-3004. You can also email Communications Planning and Implementation.

To learn the name of your department's IT Pro, consult your supervisor, your departmental website, or IT People. If you still cannot identify your IT Pro, call the UITS Support Center at 812-855-6789 (Bloomington) or 317-274-4357 (Indianapolis).

Emergency 911 notification

If you're a faculty or staff member using UniCom Enterprise Voice, you can use your UniCom client (Skype for Business) to make phone calls from remote locations as well as on campus, and these calls will use your office phone number, no matter where you are. Therefore, if you use your UniCom client to dial 911, the location reported to emergency responders will be your office. If you're somewhere else, it's better to use a cell phone or any available landline to call 911. (UniCom Basic users can only call other UniCom users by name, and thus cannot use UniCom to dial 911.)

To be activated for the UniCom service, you need to read and agree to the IU Emergency 911 Acknowledgment Statement explaining this (IU Exchange login required).

VoIP phones will transmit the location correctly if used in the location where they were installed.


IU is currently migrating from Skype for Business to Microsoft Teams at IU. During the transitional period, you can use either service (with few limitations) to communicate with multiple people via phone, instant messaging, or video. For more information on Microsoft Teams, see Get started with Microsoft Teams at IU.


To use the voice communication capabilities of UniCom, you'll need a headset, or a phone optimized for Skype for Business; "qualified" devices may not be fully supported. If you want others to see you in videoconferencing, you'll also need a webcam. Before making your decision, we recommend you contact UITS Telecom: at IU Bloomington, call 812-856-2287 option 3; at IUPUI, call 317-274-3004 option 3. You can also email Communications Planning and Implementation. For more, see About office telephone equipment at IU.

Log in

By default, Skype for Business for Windows launches automatically when you log into Windows, although you can change this setting. You can also set this option in macOS. All clients will log you in with your primary user account by default; if you need to log into an alternate account (such as a group account), you may need to sign out and log in manually. For more, see Log into UniCom with Skype for Business in Windows or macOS.

The first time you call with UniCom from outside of IU, you will need to connect to IU's VPN. Afterwards, you should not need to connect to UniCom through the VPN again.

Learn the basics

Troubleshooting, help, and feedback

If you're having trouble, try signing out of and completely closing your client software (including Outlook, if you use UniCom Enterprise Voice), and restarting to see if that resolves the problem.

For help, contact your campus Support Center.
