Configures SIP protocol for ports 5060-5068 (instead of WireShark's default of 5060) Sets the time format to human readable format Why manually configure these on your server (or worse, many servers), if we can automate it? Port 3478 is the standard port used for STUN protocol on the Lync Each has its own purpose, mind you, as Traffic Manageris designed to direct client requests to the most appropriate endpoint based on health status and traffic routing methods, while CloudApp FQDNs are used when architects build an app or service within Azure. Port 443 is the standard port used by Internal Edge services. Lync/Skype4B had very robust media stacks that were configurable to an extent (more so for on-premises customers). However, if you make peer-to-peer calls between clients or phones the ports used may fall into the media port ranges which are not captured by default. Note that both papers may be outdated and that the protocol may have changed since then (the 2006 paper definitely describes things differently from the github description).

Changed the naming of the plugin toLYNC_SKYPE_PLUGIN. However, since HTTP runs over TCP and http only shows packets using the HTTP protocol, this can miss many of the packets associated with the session because they are TCP packets (SYN, ACK and so on). The big news that Microsoft intends to (eventually) sunset Skype for Business Online in favor of Microsoft Teams has once again significantly altered the trajectory of partners and customers consuming Microsofts communications services. The protocols implement reliability in the transfer of issues and state. (Japanese). 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. Corrected some issues with decoding 0x0013 Data Attribute encapsulated data. Another interesting link is a 2004 analysis of Skype's protocol. Note: Im skipping several DNS queries just to keep things short(er), but know that there are 3-4 other FQDNs and referrals I am leaving out for brevity sake. Viewing file meta data Since you can now read any file format, and you can create any "protocol" dissector, you can create fileshark in Lua The concept of fileshark is to let you use wireshark to open various file formats, and view the file's format information as frame decoded data e. g. , view an MPEG file's internal format details .
