Using Skype for Business/Lync at IU, how can I block my number from caller ID?

Use Microsoft Skype for Business/Lync to access Indiana University's UniCom service.

Important:
As of January 22, 2017, Lync 2010 for Windows no longer works with IU's UniCom service. Windows users at IU should switch to either Skype for Business/Lync 2013, which is available from IUware as part of the Office 2013 suite), or Skype for Business 2016, which is available as an Office 365 ProPlus app. For more, see About the migration from Lync to Skype for Business.

At Indiana University, when dialing a phone call using the Skype for Business/Lync UniCom client or a USB or IP phone with UniCom Enterprise Voice, you can make a call without exposing your phone number to the other party's caller ID by dialing *67 before the 10-digit number. The caller ID of the other party will then display your number as (812) 856-9920 when calling from IU Bloomington and (317) 278-9920 when calling from IUPUI.

When using *67, you must dial the 10-digit number for all calls, including on-campus calls that you might ordinarily be able to dial with fewer digits.

If you want to block your number from caller ID for all off-campus calls you make, email Communications Planning and Implementation. Dialing *67 before the 10-digit number will always block your number from caller ID, even for UniCom to UniCom and on-campus calls.

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.

For an introduction to UniCom, including how-to PDFs and videos, see UniCom.
