Session Description Protocol (SDP)

SDP is intended for describing multimedia sessions for the purposes of session announcement, session invitation, and other forms of multimedia session initiation.

History

SDP was originally made an RFC in April 1998. A major update was published in June 2006.

Protocol dependencies

• SDP is used by other protocols to describe media sessions such as SIP, MGCP, RTSP, BICC, H248/MEGACO

Example traffic

Wireshark

The SDP dissector is fully functional.

Preference Settings

*Establish RTP Conversation. Default ON

Example capture file

XXX - Add a simple example capture file to the SampleCaptures page and link from here. Keep it short, it's also a good idea to gzip it to make it even smaller, as Wireshark can open gzipped files automatically.
