You have a Microsoft Teams Phone deployment. The 613 7010 5XXX phone number range is allocated to the Session Border Controller (SBC). A user named User1 is configured as shown in the following exhibit. User1 reports that when an external caller attempts to call the phone number of User1, the external caller receives an error message. User1 can make outbound calls, but no caller ID appears. Which two commands should you run to resolve the issues? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

Accepted Answer

C. Set-CsUser user1@litwareinc.com -OnPremLineURI "tel:+61370105555" Setting the `OnPremLineURI` for the user with `Set-CsUser` is crucial for Direct Routing, as this URI is used by the Session Border Controller (SBC) to correctly route incoming PSTN calls to the Teams user, resolving the inbound call error. The format `tel:+E.164` is standard. D. Set-CsUser user1@litwareinc.com -EnterpriseVoiceEnabled $false Setting `EnterpriseVoiceEnabled` to `$false` via `Set-CsUser` for a cloud-only Direct Routing user ensures that their voice routing is entirely handled by Teams Online and Direct Routing configuration, preventing potential conflicts with legacy on-premises voice settings that could cause issues like missing outbound caller ID.

Answer

A. Grant-CsOnlineVoiceRoutingPolicy -Identity user1@litwareinc.com -PolicyName $null Granting `-PolicyName $null` removes any assigned voice routing policy, which would typically prevent outbound calls or further exacerbate routing issues, not resolve them.

Answer

B. Set-CsOnlineVoiceUser user1@litwareinc.com -TelephoneNumber $null Setting `TelephoneNumber` to `$null` would remove the user's assigned phone number, preventing both inbound and outbound calls from working correctly.

Answer

E. Set-CsOnlineVoiceUser user1@litwareinc.com -TelephoneNumber "+61370105555" While `Set-CsOnlineVoiceUser -TelephoneNumber` is used to set the outbound caller ID, the specific issue of 'no caller ID' in this context, combined with inbound call failures, often points to a deeper configuration issue related to `OnPremLineURI` and `EnterpriseVoiceEnabled` for cloud-managed Direct Routing users.
