Question
You have a Microsoft Teams Phone deployment.
You configure Direct Routing and connect a new Session Border Controller (SBC).
You need to ensure that the Direct Routing connections support outbound and inbound calls, simultaneous ring, and consultative transfer.
What should you use to validate the connections?
Select only one answer.
A. Call Quality Dashboard (CQD)
B. Microsoft Remote Connectivity Analyzer
C. Network planner
D. SIP Tester client script
E. Teams advisor
Answer
D. SIP Tester client script
Explanation
You can use the SIP Tester client script to validate the connections for Direct Routing. The script submits an SIP test to the test runner, waits for the result, and then presents it in a human-readable format. You can use this script to test the following scenarios: Outbound and inbound calls, Simultaneous ring, media escalation, and consultative transfer.
To validate Direct Routing connections in a Microsoft Teams Phone deployment, ensuring support for outbound and inbound calls, simultaneous ring, and consultative transfer, the correct tool to use is D. SIP Tester client script.
Why SIP Tester Client Script?
The SIP Tester client script is a sample PowerShell tool provided by Microsoft specifically designed for testing Direct Routing Session Border Controller (SBC) connections. It validates critical functionalities such as:
- Outbound and inbound calls
- Simultaneous ring
- Consultative transfer
- Media escalation
The script works by submitting test SIP requests to a Microsoft service (e.g., calltester.pstnhub.microsoft.com), analyzing the results, and presenting them in a human-readable format. This makes it an ideal tool for verifying the health and functionality of your Direct Routing setup.
Steps to Use SIP Tester Client Script
- Download the Script: Obtain the SIP Tester script from Microsoft’s official documentation or resources.
- Set Up PowerShell: Ensure your environment supports the required PowerShell version and dependencies (e.g., adal.ps version 3.19.8.1).
- Run the Script: Execute the script with appropriate parameters to test your SBC connection.
- Review Results: Analyze the output for any errors or issues with call flows or features like simultaneous ringing and transfers.
Why Not Other Options?
A. Call Quality Dashboard (CQD): Focuses on monitoring call quality metrics rather than testing SBC connectivity.
B. Microsoft Remote Connectivity Analyzer: Primarily used for troubleshooting connectivity issues but does not validate SBC call flows.
C. Network Planner: Helps in planning network capacity but does not test live SBC configurations.
E. Teams Advisor: Assists with deployment recommendations but does not perform technical validation of SBC connections.
Using the SIP Tester client script ensures that your Direct Routing connections are functioning correctly and meet operational requirements for seamless communication in Microsoft Teams.
