Voice for Teams: Sync Error: missing data: SIPUserName,SIPPassword


When you attempt to perform a Teams sync in the Voice for Teams admin portal, the sync fails and the sync history log reports the following error:

  • ERROR: Failed to activate user XXX: missing data: SIPUserName,SIPPassword


Applies To

  • 8x8 Voice for Microsoft Teams
  • Microsoft Teams
  • Voice for Microsoft Teams Admin Portal


There may have been an 8x8 user profile synchronization issue when the MS Teams integration license was enabled for that user in the 8x8 Admin Console.


This process most often resolves this specific issue:

  1. Open the 8x8 Admin Console as an administrator.
  2. For each user reported with this issue in the Voice for Teams sync log, navigate to Home > Users, locate the affected user, and click the Edit / pencil icon clipboard_ee8c8f441172fb1a81ae9af44810e710f.png of that user to edit their profile.


  1. Scroll down to Services and permissions.
  2. Click the Enable MS Teams integration slider to disable the license clipboard_ec88418187a2fa6596e45576576a3a83a.png (gray).

  4. Click the Enable MS Teams integration slider again to re-enable the license clipboard_ec0168afcdaa35d618804f4d9563370d0.png (blue).
  5. Click Save again at the bottom of the page.
  6. Repeat the above process as needed for all other affected users.


  1. Finally, return to the 8x8 Voice for Teams admin portal and click Sync Now to perform another full 8x8 / Teams sync.


  1. Once the sync is completed, click the Sync Now dropdown arrow and click Show Sync History.


  1. Locate the most recent 8x8 PBX sync log in the history, and confirm that the sync was successful. The sync log should now show that the user(s) have been activated.
