Using UniCom, how do I make a phone call?

Use Microsoft Lync to access Indiana University's UniCom service.

Note: For Mac users, UITS recommends Lync for Mac to connect to UniCom at Indiana University. Communicator for Mac and Messenger for Mac are not supported.

Note: In order to place a call to anyone other than another UniCom user, you must be subscribed to UniCom Enterprise Voice. UniCom Basic users can only make PC-to-PC calls, i.e., calls using the Lync client. See IU UniCom feature comparison.

Note: In Windows, if you have a USB phone plugged into your computer and set up as your primary calling device, and you initiate a call from within the Lync client instead of dialing on the phone, your phone will ring to alert you to pick up the handset as it makes the call. For more about audio devices, including the ability to switch between audio devices during a call in Lync, see Microsoft's Lync 2010 Help for Audio Device settings.

Calling by name (all modes)

To make a call to someone by name or username (all modes):

  • If the person is already in your Lync Contact list, in the main Lync window, click the phone icon to the right of the name in your Contact list to call the person's default number.

    If you have UniCom Enterprise Voice, you may be able to call a different number. Mouse over the phone icon, click the arrow that appears on the right, and select from the drop-down list.

  • To search for someone in the IU Global Address List (GAL) and your personal Outlook Contact list (if Outlook is running), type the name or IU username into the search box in the main Lync window. A list of names will appear; to call the person, click the phone icon to the right of the name.

    If you have UniCom Enterprise Voice, you may be able to call a different number for that person. Mouse over the phone icon, click the arrow that appears on the right, and select from the drop-down list.

    Note: If you have UniCom Basic, you will only be able to place calls to other UniCom users, who will have colored circles next to their names. A clear circle indicates someone who is not a UniCom user.

Calling by number (Enterprise Voice only):

To make a call by phone number, type the phone number into the search box in the main Lync window, or dial it on your UniCom-optimized phone, as follows. If you're dialing on a phone, the phone will automatically initiate the call when you've finished dialing. If you're dialing on your computer, in Lync for Windows, mouse over the search return, and click Call. In Lync for Mac, click the picture of the contact, and then click the phone number link that appears.

  • On-campus calls (IUB and IUPUI): You can dial any on-campus number at either the IUB or IUPUI campus by dialing only the last five digits, e.g., 5-XXXX, 6-XXXX, 7-XXXX, or 8-XXXX.

  • On-campus calls (regional campuses): For calls on your campus, dial the last four digits of the number. For calls to another IU campus, dial the 10-digit number, e.g., 812-XXX-XXXX. Do not dial 9 before the number.

  • Off-campus local calls: Dial the 10-digit number, e.g., 812-333-1212 or 317-555-1212. Do not dial 9 before the number.

  • Direct dial long distance calls: Dial the 10-digit number, i.e., the area code plus the seven-digit number. Do not dial 9 before the number.

  • International calls: Dial 011 plus the international number. (You may see the numbers 256 before the 011 on your display.) Do not dial 9 before the number. When you hear the stutter dial tone, enter your Authorization Code.
Note: You can enter your Authorization Code (or numbers for a voice menu) using either your computer keyboard or your phone; in the Lync conversation window, you can also copy and paste numbers into the Dial pad. Click the Dial pad button ( 
The Display Dial pad button appears in the conversation window while your call is dialing
 ) to display the Dial pad.

To block caller ID on outgoing calls, dial *67 before the number. For on-campus calls, you must then dial the 10-digit number, as if you were calling an off-campus number (e.g., *67-812-855-XXXX).
