Here are quick troubleshooting steps for resolving outbound calling issues in Microsoft Teams:
- Check Calling Plan: Ensure the account has a valid calling plan or license assigned.
- Verify Dialing Restrictions: Confirm that the user or tenant doesn’t have any outbound call restrictions set.
- Network Settings: Check your network configuration and ensure ports required for Teams calling are open.
- Policy Settings: Review the voice policies and call settings in the Teams admin center to make sure there are no blocking rules.
- PSTN Connectivity: If using Direct Routing, verify the connection with the Session Border Controller (SBC) is operational.
- Restart Teams: Have the user log out and restart the Teams client to refresh settings.
If the issue persists, escalate to Microsoft support or your telecom provider for further assistance.
