Question #2
You have a Teams Phone deployment that uses Direct Routing on a single Session Border Controller (SBC).
Users report that outbound PSTN calls are failing, but inbound PSTN calls are successful.
When you review the SBC logs, you discover that Microsoft is responding to SIP option requests, but is NOT sending SIP option requests.
What is the cause of the issue?
Users report that outbound PSTN calls are failing, but inbound PSTN calls are successful.
When you review the SBC logs, you discover that Microsoft is responding to SIP option requests, but is NOT sending SIP option requests.
What is the cause of the issue?
- AThe online PSTN gateway is disabled.
- BAn SBC certificate is expired.
- CAn external DNS entry is missing from the FQDN of the SBC.
- DThe phone numbers of the users are defined by running the New-csTeamsUnassignedNumberTreatment cmdlet.
Correct Answer:
C
GPT
The cause of the outbound PSTN call issues in a single SBC Teams Phone deployment using Direct Routing is typically due to the online PSTN gateway being disabled. This affects the system's ability to initiate outbound calls while still receiving inbound calls, correlating with the symptoms described. Please verify the status of the online PSTN gateway through the Teams admin center or using PowerShell to resolve this issue.

To effectively handle the needs of the sales department where a call is routed to multiple users and behaves differently after hours, the best solution integrates 'call queues' and 'auto attendants'. 'Call queues' are essential as they enable the distribution of phone calls to a group of users, thus accommodating multiple users handling incoming calls. 'Auto attendants', on the other hand, are crucial for managing calls beyond regular business hours. They provide the functionality to greet callers with custom messages and routing options, optimizing call management around the clock. Utilizing these two features ensures efficient and precise call routing suited to business needs.

Question #4
DRAG DROP -
You have a Microsoft Teams Phone deployment.
You need to create two call queues named CQ1 and CQ2. The solution must meet the following requirements:
CQ1 must balance incoming calls so that each call agent receives the same number of calls
Calls received by CQ2 must ring all call agents simultaneously
What should you configure for each requirement? To answer, drag the appropriate routing methods to the correct requirements. Each routing method 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.

Question #6
You have a Microsoft Teams Phone deployment that contains two users named User1 and User2.
User1 will be on leave for two weeks.

Correct Answer:
C

GPT
To redirect calls for a user in Microsoft Teams Phone deployment effectively, modifying the call delegation settings is key. This enables another user (User2, in this scenario) to receive calls intended for the first user (User1), thus ensuring smooth communication flow during User1's absence. This approach not only suits the scenario but also reduces administrative effort, as it's straightforward to set up directly in the Teams administrative center or via PowerShell, bypassing more complex call-routing adjustments. Adjusting delegation settings is preferable in ensuring that no calls are missed and are handled by a designated backup.

Correct Answer:
ABD
GPT
For this scenario involving a Microsoft Teams Phone deployment where the call queue 'Customer Service' needs a specific outbound calling presentation, the necessary steps include creating a new caller ID policy and setting 'Replace the caller ID with to Resource account.' Adjusting the 'Override the caller ID policy to On' is crucial for applying these custom settings explicitly to the 'Customer Service' queue without affecting other users. These tailored settings ensure that all outbound calls from this queue reflect the required calling name and number, aligning with organizational requirements.

- CRun Grant-CsTeamsEmergencyCallingPolicy -Identity Vancouver.
- DAdd a new emergency location for User1.
Correct Answer:
B
GPT
When updating a user's emergency location in Microsoft Teams, it’s vital to first ensure the user's profile reflects their actual geographic location. Changing the Usage Location in the user's profile is foundational, as this directly impacts the ability to assign relevant emergency addresses and policies compliant with local regulatory requirements. Failing to update the usage location can prevent the application of correct emergency settings due to geographical restrictions on available emergency addresses and policies, therefore, before assigning any new emergency details, update the usage location accordingly.
