Hello John,
Good day! Thank you for posting to Microsoft Community. We are glad to assist!
Based on your description, I understand that you are having issues with Calls being forwarded to your Teams account on your work computer.
To better understand and narrow down the issue, please help share more details on this issue by answering below questions. Thanks in advance.
- Are you using Microsoft 365 work/school account or a Microsoft hotmail.com/live.com/outlook.com personal account?
- Are you logged into "Your Job-Computer" with more than one account?
Can you please confirm if you're having issues with the below scenario as I understood from your description:
You have a phone number you got from an ISP/ or land line -> This phone number is in your mobile device -> When someone calls this number, you receive a call from your Teams work account on your PC?
Can you please clarify your call flow for us.
I will be looking forward to your response on this. Please note that our initial response does not always resolve the issue immediately. However, with your help and more detailed information, we can find a solution together. Thank you for your help.
Thank you very much for your cooperation and understanding.
