If you're having trouble making calls on Microsoft Teams, there are several potential issues to consider:
- Calling License: Ensure that you have the appropriate calling license. If you receive an error message stating that you can only call people within your organization, it may indicate that you are not enabled for the Enterprise Voice feature. You should contact your IT administrator to check your license status.
- Device Registration: If you are using SIP devices, make sure that your device is properly registered. You can also try restarting your device to see if that resolves the issue.
- Valid Phone Number: If you are trying to call a Public Switched Telephone Network (PSTN) number, ensure that the number is valid and properly formatted. If you receive an error message indicating that something went wrong, it may be due to an invalid phone number.
- Country/Region Code: If you are calling from a contact, account, or lead record in Dynamics 365 Sales, ensure that the number includes the country code. If the country/region code prefixing is enabled, you may need to disable it in the settings.
If these steps do not resolve your issue, you may want to refer to the Microsoft Community for further assistance.
