Explanation

To transition a phone number from a physical device (Common Area Phone/User usage) to a Call Queue (Service usage), you must follow a specific lifecycle:

Unassign: A number cannot be modified or reassigned while it is actively linked to a user or device. You must first remove the current association.
Change Usage Type: Microsoft distinguishes between "User" (Subscriber) numbers and "Service" numbers. Call Queues and Auto Attendants require Service numbers. You must convert the usage type in the Teams Admin Center or via PowerShell to make it compatible with a Resource Account.
Assign to Resource Account: Once converted, the number is assigned to the Resource Account associated with the Call Queue to route incoming calls.

Q: 2

You have a Microsoft Teams Phone deployment You assign a Microsoft 365 E5 license lo a user named User1. You need to enable User1 for Direct Routing. Which PowerShell cmdlet should you run?

Options

Correct Answer:

Explanation

To enable a user for Microsoft Teams Direct Routing using PowerShell, you must configure their account with their specific phone number and enable them for Enterprise Voice. The Set-CsUser cmdlet is the correct tool for this task. It allows an administrator to set the essential -OnPremLineURI parameter to the user's E.164 phone number and the -EnterpriseVoiceEnabled parameter to $true. These settings configure the user's account to route calls via the on-premises Session Border Controller (SBC) defined in the Direct Routing configuration.

Why Incorrect

A. Set-CsCallingLineIdentity: This cmdlet is incorrect because it is used to create or modify Calling Line ID (Caller ID) policies, which control the phone number displayed on outgoing calls, not to enable a user for a specific voice routing method.

C. Set-CsOnlineVoiceUser: This cmdlet is incorrect for this specific task because it does not have the -OnPremLineURI parameter, which is required to assign a phone number for Direct Routing. It is typically used for other voice configurations.

D. Set-CsUserServicesPolicy: This cmdlet is incorrect as it is used to manage user services policies that control features like unified contact store, presence, and archiving, which are not directly related to enabling voice routing.

References

1. Microsoft Docs - Enable users for Direct Routing: This official documentation explicitly details the steps to enable a user for Direct Routing.

Reference: In the "Enable user and assign a phone number" section

the document states: "You can use the Set-CsUser cmdlet to configure the phone number and enable Enterprise Voice and voicemail for a user." It provides the following example command: Set-CsUser -Identity "[email protected]" -OnPremLineURI "tel:+14255550100" -EnterpriseVoiceEnabled $true -HostedVoiceMail $true.

2. Microsoft Docs - Set-CsUser Cmdlet Reference: The official documentation for the Set-CsUser cmdlet lists and describes its parameters.

3. Microsoft Docs - Set-CsOnlineVoiceUser Cmdlet Reference: The documentation for this cmdlet shows its parameters

confirming the absence of -OnPremLineURI.

Reference: The parameter set for Set-CsOnlineVoiceUser includes -TelephoneNumber but not -OnPremLineURI

making it unsuitable for the primary step of enabling a user for Direct Routing.

Q: 7

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. A) B) C) D) E)

Options

Correct Answer:

B, E

Explanation

For Direct Routing to function correctly, the user must be assigned a LineURI with the PhoneNumberType set specifically to DirectRouting. The current configuration likely treats the number as a Microsoft Calling Plan number or is in an inconsistent state. Running Option B (Set-CsPhoneNumberAssignment) correctly attributes the number to the Direct Routing service. Additionally, the user is currently assigned a specific voice routing policy ("VIC-All"). In many Direct Routing configurations, clearing a custom policy to use the global default or ensuring the policy is re-evaluated by setting it to $null (Option E) is a necessary step to reset the routing logic and ensure the SBC handles the traffic correctly.

Why Incorrect

Option A: This command removes the phone number assignment entirely, which would prevent the user from making or receiving any calls.

Option C: Set-CsOnlineVoiceUser is a legacy cmdlet primarily used for Skype for Business Online; modern Teams environments use Set-CsPhoneNumberAssignment.

Option D: Disabling EnterpriseVoiceEnabled would strip the user of all Teams Phone functionality, making it impossible to place or receive calls.

Minimal disruption only works if admin sets up in TAC first, then configures User2’s receive-only and settings block, then has User1 confirm as delegate in client.

Aisha H. Jan 12, 2026 1:08 pm

D then F then A is correct. Start in TAC on User1's Voice tab, set User2 just to 'Receive calls' with no ability to change settings, then have User1 finish it in the Teams client. Pretty sure this order keeps it low impact and secure, but let me know if I'm missing something.

Leo Jan 5, 2026 7:58 am

Yeah, looks like it should be: User1 Voice tab in TAC first, then set User2 to Receive calls only with no change rights, then have User1 sign in and set the delegate. Doing the admin parts first keeps things smooth for User1. I think that's the best order but not 100 percent sure if client-side is strictly always needed now.

Layla D. Jan 15, 2026 7:09 pm

Really clear question, nice breakdown! I went with: Step 1: From Users in TAC open User1's Voice tab, Step 2: For User2 set Receive calls and block changing call settings, Step 3: Instruct User1 to sign in and configure delegate. I think this lines up since we want least privilege for User2 and minimal impact for User1 (so do admin steps first). Not totally sure if the client step is always needed but it felt safest here. Agree?

Step 1: From Users in the Microsoft Teams admin center, open the settings of User1, and then select the Voice tab.
Step 2: For User2, set Permission to Receive calls, and then set Allow changing call settings to Off
Step 3: Instruct User1 to sign in to the Microsoft Teams client, establish a remote session to his computer, and then configure the delegation settings in the Teams client.

AmeliaY Jan 18, 2026 12:29 pm

This matching is so confusing, I put: open User2 Voice tab in admin center, then give them Make and receive calls, then remote into User1 for delegation. Seems right from the interface?

Be respectful. No spam.

Q: 9

DRAG DROP Your company has a main office in New York and a branch office in Calgary. All offices connect to each other by using a dedicated WAN. You have a Microsoft Teams Phone deployment. You need to recommend a Direct Routing solution that meets the following requirements: • If a Session Border Controller (SBQ fails in the New York office, PSTN services must remain available through a local PSTN egress in New York. The Calgary office must prioritize a local PSTN egress and ensure that PSTN services remain available in the event of a local SBC outage. • The number of SBCs must be minimized. What should you recommend for each office? To answer, drag the appropriate components to the correct offices. Each component may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content. NOTE: Each correct selection is worth one point.

A cross-site SBC pair
A local redundant SBC pair
A single SBC
PSTN over WAN

Correct Answer:

Answer Areas New York: B. A local redundant SBC pair Calgary: D. PSTN over WAN

Explanation

New York Office: The requirement states that if an SBC fails, PSTN services must remain available through a local PSTN egress. To achieve local failover within the same site without relying on another geographical location, you must deploy a local redundant SBC pair (typically configured as a High Availability cluster). This ensures that the failure of a single physical unit does not disrupt the local egress.

Calgary Office: The requirement is to prioritize local egress but ensure availability during an outage while minimizing the number of SBCs. By selecting PSTN over WAN, Calgary can use the redundant SBC infrastructure in New York as a backup path. This satisfies the survivability requirement without needing to deploy a redundant pair at the branch site, thus minimizing hardware.
