Get started with UniCom/Lync/Skype for Business

On this page:

Eligibility and account types

All Indiana University students, faculty, and staff are eligible to use some features of the UniCom service, which provides unified communications via the Microsoft Lync/Skype for Business clients. Students, as well as faculty and staff members with no IU phone number, may use UniCom Basic, which operates independently of a phone number. Faculty and staff members with a traditional phone line may use UniCom Basic alongside their phone service. Telephone service for all faculty and staff will eventually be converted to UniCom Enterprise Voice, which replaces traditional phones, but individual faculty and staff members may choose to sign up for Enterprise Voice in advance of department conversion.

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 or your departmental website. 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

To be activated for the UniCom service, first read and agree to the IU Emergency 911 Acknowledgment Statement (IU Exchange login required). As described more fully in that statement, computer-based phone services have inherent limitations with connecting to location-specific services, such as the emergency response services accessed by dialing 911. This is chiefly a problem when using UniCom Enterprise Voice to make calls from a location other than your desk. If you make a call from your desk using UniCom Enterprise Voice, your location should still be transmitted to emergency responders correctly. VoIP phones will transmit the location correctly if used in the location where they were installed. Also, newer cell phones use either GPS or triangulation to determine location. (UniCom Basic users can only call other UniCom users by name, and thus cannot use UniCom to dial 911.)



  • Skype for Business: Skype for Business (formerly Lync) is available via:
    • Office 365: You can download and install Skype for Business 2016 as part of Office 365 ProPlus.
    • Office 2013: You can download and install Office 2013 from IUware. Office 2013 includes Lync 2013, which should update to Skype for Business automatically when you launch it.


Mobile clients


To use the voice communication capabilities of UniCom, you'll need a headset, or a phone optimized for Lync; "Lync-qualified" devices may not be fully supported. If you want others to see you in videoconferencing, you'll also need a webcam. For more, see About office telephone equipment at IU.

Learning the basics

To learn how to perform common tasks in the Skype for Business/Lync client, see the UniCom page. Also, see Microsoft's Skype for Business help pages or the Lync for Mac user guide.

Troubleshooting, help, and feedback

To get help with UniCom, or comment about the service, contact the Support Center. If you're having trouble, you can also 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.
