When I started using Wireshark with Lync / Skype for Business I found A tag already exists with the provided branch name. This port in theory should always be 3478. Wireshark is the best network traffic analyzer and packet sniffer around. ACK: Provides information on the state of a Reader to a Writer. They also have a Parser pack for Lync that will decode STUN and RTP messages. In the packet detail, closes all tree items. For any seasoned Lync/Skype admin, we all know that specific DNS records are required in order for the client to discover the FQDNs for the pools the accounts is homed to. config . a Wireshark pcap file) and tell me the For enterprise customers, Skype4B offered defined source ports you would see client traffic originated from (50,000-50,059 UDP/TCP). I count at least three separate source ports utilized by my client when communicating to the cloud MCU: It was difficult to determine which modality was using which source port unfortunately (and especially difficult since Teams doesnt produce logs that can be examined in Snooper), but Im pretty confident that 8085 was my audio stream. Applying a filter to the packet capture process reduces the volume of traffic that Wireshark reads in. The protocol type eld lists the highest level protocol that sent or received this packet, i.e., the protocol that is the source or ultimate sink for this packet. Their success attests to the generality and power of these protocols. The plugin by default will listen on port TCP 443 and UDP 3478 for traffic, this will capture traffic that is sent to Edge (and other) servers. . There is a good deal of TLS encrypted traffic following the resolution of pipe.cloudapp.aria.akadns.net, but eventually another DNS query is triggered for: The DNS query response gives us a separate CNAME record: The resulting IP address is 13.107.3.128, but an important note is that the FQDN of the IP is associated with the Microsoft Edge node network, msedge.net. Some examples of Indeed the DNS queries prove that there absolutely is connectivity to at least some portion of the Skype4B Online infrastructure: Theres no configuration in the client anywhere for the legacy webdir discovery record, so this must be a hard-coded behavior that triggers the resolution process. Changed the naming of the plugin toLYNC_SKYPE_PLUGIN. also be used to decode protocols. Here are some So there may be cases where you edge .

This article describes how Teams uses Microsoft 365 or Office 365 call flows in various topologies. If you're wiling to compile from source, you can build it in. that some protocols are not decoded properly by Wireshark, which made me sad. RTPS is designed to run on an unreliable transport mechanism, such as UDP/IP. Office Protocol documents, RFCs, and a healthy dose of reverse engineering, I Fortunately, Wireshark does a great job of making this easy. More specifically, only IPv4 packets that consist of TCP/UDP/ICMP segments/datagrams/messages should be captured. Widened the scope of RTP port classification from 1024-59999 I will endeavour to maintain the plugin will always be 443, however, its a variable for if something changes in the I am aware that skype encrypts all the outputs. Two separate CNAME records are returned for this query: The resulting IP address is 40.117.100.83, but given the usage of CDN is in play, this IP address will vary for others across the globe. -- - Dissector can be turned on/off within Wireshark Preferences. It can capture packets in a connection between two PCs, between a server and a PC, or between a LAN and the internet. Use Raster Layer as a Mask over a polygon in QGIS. External settings.
