Troubleshooting Microsoft Teams — Question 4

You are managing a Microsoft Teams environment for a company. You are setting up direct routing on a partner-hosted session border controller (SBC).
The SIP proxy does not receive SIP options from the SBC.
You need to resolve the issue.
What are two possible ways to achieve the goal? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.

Answer options

• A. Ensure that the Secure Real-Time Transport Protocol (SRTP) is enabled.
• B. Replace the partner-hosted SBC with a self-deployed SBC.
• C. Ensure that the SBC certificate is from a trusted Certificate Authority (CA).
• D. Modify the FQDN in the SIP profile to match the SBC certificate.

Correct answer: C, D

Explanation

The correct answers are C and D because having a valid certificate from a trusted Certificate Authority (CA) ensures secure communication, which is critical for SIP operations. Additionally, modifying the FQDN in the SIP profile to align with the SBC certificate is necessary for successful validation. Options A and B do not directly address the SIP options issue, making them ineffective solutions in this context.
