To verify voicemail and call forwarding configurations in Microsoft Teams, the Get-CsUserCallingSettings cmdlet is the specific tool used to retrieve a user's call forwarding, simultaneous ringing, and voicemail settings. While Get-CsOnlineUser provides general account info, it does not drill down into specific call routing targets. The policy requires callers to record a message or be transferred; therefore, verifying the UnansweredTarget (the destination for unanswered calls) is essential to ensure calls are correctly routed to the voicemail system or the reception desk as mandated.
