Hi Wilson007,
Is this still ongoing or could it be fixed with the Microsoft Support?
You might check the Teams Calling Policy to disable it now or later, did you already see and read that Microsoft plans to rollout spam call notifications for Teams which seems to be the "feature" you are already having and experiencing.
I wrote an article about it: https://erik365.blog/2021/08/15/microsoft-teams-spam-call-notifications/ also covering the Teams Calling Policy parameters to enable/disable it, e.g globally with Set-CsTeamsCallingPolicy -Identity Global -SpamFilteringEnabledType "Disabled"
Erik365Online, I used the information from your blog to disable the feature and now calls are incoming calls are showing normal. I enable it and it happens again. I also opened a case with Microsoft and they told me they could not provide more information on what SIP header they are using for that classification.
- No documentation available for a GA feature.
NOTE: it can put your 'Contact Center out of service'

- Any further word on what criteria Microsoft is using to filter calls when they mark them as "Likely spam"?
- Good to hear.
Like you, I'm also waiting on some more details (in the documentation) on the spam call notification behavior and process in regards on how a call is marked as spam, e.g. based on what evidence and data.
