Your company hires a new employee in Lisbon.
You assign a Microsoft 365 E3 license to the employee.
The employee must schedule meetings that will include customers in Lisbon. The customers will dial in to the meetings by using PSTN.
You need to ensure that the employee can send meeting invitations that include a dial-in conferencing bridge. The bridge must be set to a local number in Lisbon instead of the company's default dial-in conferencing bridge number.

Hotspot Question
You have a Teams Phone deployment for your company. The company is settings up Direct Routing and it adds a Session Border Controller (SBC). The manager reports that users cannot make calls normally on devices running Windows 10.
You need to troubleshoot the issue.
What should you do? To answer, select the appropriate options in the answer area.
Correct Answer:
Explanation:
You should access the Teams admin center portal. The Teams admin center portal is the place where you can manage the settings and configurations of the company's Teams. You can use this portal to manage objects within Teams, such as users, channels, etc. You can also access a health dashboard related to Direct Routing where you will find details related to any issues occurring with users. One of the reasons why the users cannot make calls may be related to a Transport Layer Security (TLS) connection issue caused by the Session Border Controller (SBC) certificate that must be valid, and neither expired nor revoked.
You should not access the Azure portal. You can use the Azure portal to manage your tenant's objects, such as users, groups, etc. This portal provides identity services for users and protection for sign-ins to your tenant's apps. It also provides protection against domains that you do not want your users to be able to access through the tenant's apps.
You should not access the Microsoft 365 compliance center. You can use this portal to manage the privacy policies for your tenant and to protect your tenant's information using the variety of tools that it provides, such as data classification tools and data connectors.
You should also use a certificate generated from a valid Certificate Authority (CA). These certificates are the ones that an SBC must have in order to ensure that no TLS connections can occur. As previously mentioned, if the certificate is not valid, these connection issues will occur.
To obtain a valid certificate, you must send a request to a valid CA in order for them to generate a certificate that can be used with the SBC.
You should not use a Service certificate. This is a certificate that is attached to cloud services within Azure. You can use Service certificates to achieve a secure connection between your system and a cloud service that uses a Hypertext Transfer Protocol Secure (HTTPS) endpoint.
You should not modify the Devices setting in the Teams admin center. You can use this setting to manage the fields that are related to the Surface Hub devices that are used in Teams meetings.
You would modify the Devices setting if you wanted to enable or disable Surface Hub accounts from sending mails within Teams.
You have a Microsoft Teams Phone deployment.
You need to ensure that when a user dials an emergency number, the security desk receives a notification to join the call.
Which type of policy should you configure?
Correct Answer: C 🗳️
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
Your company uses configuration profiles to manage Microsoft Teams-certified IP phones. The Standard configuration profile is applied to the IP phones. The help desk receives reports that several user phones fail to lock automatically after the timeout period.
You need to verify whether the configuration profile is applied to the problematic phones.
Solution: From Users in the Microsoft Teams admin center, you locate each affected user and review the settings on the Voice tab.
Does this meet the goal?
Correct Answer: A 🗳️

Case Study 1 - Litware, Inc
Overview
Litware, Inc. is an online retailer.
Litware is replacing its telephony platform with Microsoft Teams Phone.
Currently, all users are assigned Microsoft 365 E3 licenses.
Existing Environment
Telephony Environment
The existing telecommunications system has several third-party IP-PBXes at the corporate and warehouse sites. Currently, the PBXes are linked through the corporate WAN and an inter-office dial plan is in place.
A unique PSTN direct inward dial (DID) is assigned to each user. The last five digits of each DID are used as an extension.
Litware piloted Microsoft Skype for Business Server Enterprise Voice, but has since decided to migrate directly to Teams Phone. During the pilot, a response group was created, and the response group is still in use. Agents in the response group use Skype for Business Server- certified handsets.
Locations
Litware has global retail stores and datacenters.
The telephony topology contains the following four types of sites:
Corporate sites
The corporate sites contain information workers who collaborate by using the Teams desktop client and SharePoint Online.
The reception desk at each corporate site has an analog intercom with an integrated door control.
Each intercom connects to an existing PBX by using an FXS Analog Telephony Adapter (ATA).
SIP trunks are delivered directly to the site by using a resilient WAN that connects directly to the on-site PBX solution.
Warehouse sites
The warehouse sites are critical to the business. Users at these sites use either the Teams desktop client or the Teams mobile client.
Each warehouse has a public announcement (PA) system that connects to the PBX by using a SIP ATA, along with the sites' existing ISDN trunks.
Currently, users at the company's warehouse in Georgia can call the PA system by dialing
123456.
All calls to emergency services from the warehouses are played over the warehouses' PA system automatically.
WAN connectivity at the warehouses can be unreliable, so local PSTN connectivity is preferred as compared to centrally hosted connectivity.
Retail sites
Each retail site has only one or two desk phones and a specialized point of sale (POS) computer that cannot run the desktop or web versions of the Teams client.
Users at the retail sites have the Teams app and an associated data plan installed on their mobile device.
Currently, each retail uses a managed SD-WAN appliance to connect to both the internet and the corporate WAN.
The users report that in the event of an internet outage at the retail sites, they can use their mobile devices, which have strong reception.
Requirements
Planned Changes
Litware plans to implement the following changes:
* Maintain the existing emergency call PA integration.
* Replace the existing IP-PBX solutions by using Teams Phone.
* Consolidate all its PSTN trunks by using region-specific datacenters, whenever possible During the planned deployment of Teams Phone, Litware will open a new retail site in the United Kingdom that will have five users. Litware does not have any existing telephony in the United Kingdom. Management at the new retail site wants to use Microsoft Teams Calling Plans for the users.
You are opening a new warehouse site in Melbourne. The new warehouse will connect to a phone carrier by using a Session Border Controller (SBC). Dialing rules are an area code of two digits beginning with a zero followed by a subscriber number of eight digits. For example, an
E.164 number of +61370105550 will be translated to 03 7010 5550 and +61255505550 will be translated to 02 5550 5550.
Technical Requirements
Litware identifies the following technical requirements:
* Minimize the amount of voice traffic over the WAN.
* Whenever possible, use natively supported Teams solutions.
* Avoid replacing existing analog device adapters and SIP phones.
* Assign a Microsoft 365 Phone System license to all the users listed in a CSV file.
* Ensure that the retail sites can place and receive calls in the event of a WAN failure.
* Assign a phone number of +61370105550 to a user named User1. User1 is located at a corporate site.
* Ensure that the warehouse sites maintain calling in the event of an internet outage or Teams service failure.
* Provide users at the United Kingdom retail site with phone numbers. The users must only be allowed to make in-country calls.
* Replace the response group from the Skype for Business Server Voice Enterprise pilot with a call queue. The agents must be able to use their existing handset.
Hotspot Question
You need to assign a license to users to meet the technical requirements.
How should you complete the PowerShell script? To answer, select the appropriate options in the answer area.
