You have a Microsoft Teams Phone deployment.
You need to implement PSTN connectivity by using Direct Routing.
What are three requirements for the implementation? Each correct answer presents part of the solution.
NOTE: Each correct selection is worth one point.
To implement PSTN connectivity using Direct Routing in Microsoft Teams Phone deployment, three requirements must be met: Firstly, a public DNS entry is needed to map the FQDN of the Session Border Controller (SBC) to a public IP address. This allows the SBC to be reachable over the internet. Secondly, a firewall rule must be in place to open a TCP signaling port to Microsoft Teams since Microsoft Teams uses TCP for signaling. Lastly, a Teams-certified Session Border Controller (SBC) is essential to ensure compatibility and reliable operation with Microsoft Teams. Opening a UDP port for signaling is incorrect as signaling in Microsoft Teams occurs over TCP, not UDP.
Answer is correct as the question says UDP *SIGNALLING* port - signalling in Teams is over TCP so opening the UDP ports for signalling answer is invalid here - had it been UDP media ports then there would have been an issue.
Agreed answers are correct TCP is signaling UDP is Media
Signaling port TCP is correct. MS Teams uses 5067 TLS for signaling which is TCP based.
i think the answer should be: C - D - E it is recommended to open UDP Ports 3478,3479,3480,3481 from Teams Client to TR/MP which are in the Microsoft Global Network, if the UDP is blocked by firewall the TCP will be used.
Signaling to Teams is TCP 5061. UDP is mediastream and not signaling.
yes, you are right.
yes, you are right.
anyone who passes this exam, may i know the 55q can pass the exam? I just faild twice for ms-720 exam,just.....wuhawu
