Teams call forwarding shows forwarded call as anonymous

Question

Hi

I configured call forwarding on my teams client to my mobile.
When I now receive a forwarded call on my mobile, it doesn't show me the caller number, instead the call is shown as anonymous.

I am sure that worked before.

We use direct routing, and we have a session border controller installed.

Regards
Peter

Hi @Peter,

Welcome to Q&A!

Before the troubleshooting, please kindly share more information here:

2. Are there any related changes before this issue occurs? Such as the normalization rules, dial plans or anything else.
3. Could you accept the call on your mobile even the caller id show as anonymous?
4. How many users experience this kind of issue?
5. Does this issue happens on both IOS or Android client?
6. Is there any different setting between the affected user and non-affected users?

For this call forwarding issue, we have some suggestions as below for troubleshooting:

1. If you're an administrator, please Run Diagnostic tool (https://aka.ms/TeamsCallForwardingDiag) to validate if your Teams account is configured correctly to forward calls received in Teams to a specific number.

The detailed steps to use the tool are documented in this article (Configure call forwarding and delegation settings - Microsoft Teams), the tests will return the best next steps to address any user settings or configurations to validate that the user is properly configured to forward calls to a specific number in Teams.

2. Comparing the call forwarding related settings for both affected users and non-affected users and attempt to change the settings as the same as the non-affected users to see if it could resolve the issue.

Running this cmdlet could get the detailed settings for users: Get-CsUserCallingSettings -Identity "yourTeamsAccount"
