Office telephone service for faculty and staff at Indiana University has transitioned from Skype for Business to Teams Calls.

System administrators are aware of the following issues with Indiana University's UniCom service:

Issue	Modes affected	Description
Loud or persistent dial tone after a call or meeting between Skype for Business and Teams Calls is completed.	UniCom Enterprise Voice	Interaction between Microsoft Teams and Skype for Business may cause Skype for Business users to hear a persistent dial tone or off-hook sound even after their call or meeting is completed. Microsoft is working on a Teams update which will likely solve this problem. As a workaround, exit and then restart Skype for Business and/or the Teams app, or restart the computer. This issue should no longer occur when all call or meeting participants are converted to Teams Calls.
"Vacant or Disconnected" error message is heard when dialing a number.	UniCom Enterprise Voice	If a Skype for Business user has their number set to forward or simul-ring to a team call group, delegate, or other number, and any of the numbers are vacant or disconnected, the caller will hear an error message. Solution: Adjust your call forwarding.
"Vacant or Disconnected" error message is heard when dialing a number.	UniCom Enterprise Voice	If a Skype for Business Response Group (usually a main number) is set to ring one or more other numbers and any of the other numbers are vacant or disconnected, the caller will hear an error message. Solution: Adjust your call forwarding.
Skype for Business Response Group does not ring Skype for Business on Mac.	All	When users of Skype for Business on Mac use equipment other than a physical IP desk phone, a Response Group main number's call routing may not ring the user. Skype for Business Windows users are not affected.
Polycom VVX500 series phone locks and signs out	UniCom Enterprise Voice	Some Polycom VVX500 series phone users may experience unexpected screen locking and signing out; UITS is working with the phone vendor to correct this problem.
Status does not update based on Exchange calendar appointments and meetings	All	When logged into Unicom via the mobile or Mac clients, the status will not change to busy when an appointment or meeting starts. The issue can be resolved for the Mac, but not mobile, by updating to the latest version. Windows clients are not affected.
Polycom VVX500 series phone doesn't allow simultaneous ring to be assigned via the phone	UniCom Enterprise Voice	Polycom VVX500 series phone doesn't allow simultaneous ring to be assigned via the phone; use the Skype for Business client instead. For instructions, see ARCHIVED: Use Skype for Business team calling in UniCom.
Outgoing caller ID displays "IU Trustees"	UniCom Enterprise Voice	Outgoing off-campus calls display "IU Trustees" as the caller ID name. This issue has been submitted to the vendor for correction.
Outgoing calls immediately disconnect in Lync for Mac 2011 v.14.0.5	UniCom Enterprise Voice	Outgoing calls immediately disconnect in Lync for Mac 2011 version 14.0.5. This problem is fixed in version 14.0.6 or later. UITS recommends upgrading to the latest version, available from IUware.
Outlook or Lync for Mac hangs	All	Some Mac users have reported Outlook or Lync becoming unresponsive or taking an excessively long time to complete an action; this happens most frequently on loading. UITS recommends applying the latest updates from Microsoft for both Office and Lync to address this problem.
Trouble making and receiving calls when using Windows Switch User functionality	All	Skype for Business clients will not work properly when multiple users are logged into the same computer. Users need to log out of the computer, as opposed to using Switch User, in order for calls to work correctly.
When dialing an international number from the Skype for Business client, call ends abruptly after the caller enters an Authorization Code.	UniCom Enterprise Voice	When dialing an international number from the Skype for Business client, if the international number is busy, the call will end after the caller has entered an Authorization Code. The caller will not hear a busy signal.
Skype for Business showing incorrect name for person who answers a call	All	This issue occurs when using Skype for Business to call a number shared by a group of people. Due to the method used by the software to locate the number in the directory, the conversation window for the active call may not display the name of the person who actually answered the call.
Voice mail not answered by intended recipient	UniCom Enterprise Voice	If you configure Skype for Business to forward unanswered calls to a colleague, and a call to you then rolls over to your colleague's voice mail, callers may be surprised to reach your colleague's voice mail rather than yours. Other Skype for Business users will see that the call is being forwarded, but callers using standard phones will be unaware of the forward. As a workaround, instead of forwarding your calls, choose to simultaneously ring your colleague's number; see ARCHIVED: Use Skype for Business team calling in UniCom.
