Microsoft Teams Incoming call via Direct Route shows "Spam Likely" for 4-digit extension
Well this was working just fine until "New calling experience" was rolled out in the latest Teams client version. You have to keep in mind that Direct Routing is not just meant to connect to the PSTN but also to be able to seamlessly communicate to on premise PBX systems which more often than not are not configured for E164 format. I use Cisco CUBE for most implementations which is very simple to configure and I do follow to the T the Cisco and Microsoft configuration guide so I'm not trying to reinvent the wheel here. What I need is for Microsoft to find a way to let 4 or 5 digits in the calling number come across the Teams client without any Spam Likely label which in my opinion is absurd. I know I can manipulate the digits in the CUBE and force an E164 number appear in the Teams client but that defeats the purpose because customers don't want to see the full number for their own business reasons. Believe me, I've tried persuading customers into E164 format but not all like the idea, specially when it interferes with business processes. Spam Likely labeling should be optional like a policy in my humble opinion. Erik365Online

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"
- JCarmonaGAug 25, 2021Copper ContributorErik365Online, 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.
- Erik365OnlineAug 29, 2021Steel ContributorGood 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.
