Hi, Our company will deploy Ms-Team VOIP phone system soon, with the combination of soft phones (pc based clients) + Yealink SIP-T series physical handset.
1. First thing wanted to ask is MS-TEAM is NOT using RTP tunnelling inside of HTTP/HTTPS right????
It suppose to be separate, RTP for data plane, HTTP/HTTPS for signalling?
2. Also wondering if anyone can help me confirm the below tables of IP network protocols is correct?
Plane | Media Traffic Type | User source port | Destination port | Protocol |
Data | Voice | UDP 50000-50019 | UDP 3478-3481 | RTP over UDP |
Data | Video | UDP 50020-50039 | UDP 3478-3481 | RTP over UDP |
Data | Screen Sharing | UDP 50040-50059 | UDP 3478-3481 | RTP over UDP |
Signaling | TCP 80 and 443 | HTTP/HTTPS |

@danfeng The strong preference is for Teams to use UDP, but if that's not available it will then use HTTPS. HTTPS will have higher latency and lead to lower call quality. I wouldn't normally refer to is as RTP over UDP, just UDP.
Your ports look right to me, strictly I think 3479 is voice, 3480 video and 3481 screen sharing (3478 being for STUN).
