Block your IU office number from caller ID

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

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.

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.

The caller ID of the other party will then display your number as one of the following numbers, based on your campus:

Campus Number
IU Bloomington 812-856-9920
IUPUI 317-278-9920
IU East 765-973-8898
IU Kokomo 765-455-9548
IU Northwest 219-981-4228
IU-Purdue Columbus 812-375-7520
IU South Bend 574-520-4329
IU Southeast 812-941-2899

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.
