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 Ethereal can open gzipped files automatically. attachment:SampleCaptures/aaa.pcap Sample SIP and RTP traffic.

Session Initiation Protocol (SIP)

The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol for sessions.

These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences. SIP can create, modify, and terminate sessions with one or more participants.

The SIP protocol is a member of the ["VOIPProtocolFamily"].

History

XXX - add a brief description of SIP history

Protocol dependencies

Example traffic

attachment:SIP.jpg

Ethereal

The SIP dissector is (fully functional, partially functional, not existing, ... whatever the current state is). Also add info of additional Ethereal features where appropriate, like special statistics of this protocol.

Preference Settings

(XXX add links to preference settings affecting how SIP is dissected).

Example capture file

attachment:SampleCaptures/aaa.pcap Sample SIP and RTP traffic.

Display Filter

A complete list of SIP display filter fields can be found in the [http://www.ethereal.com/docs/dfref/s/sip.html display filter reference]

  • Show only the SIP based traffic:

Capture Filter

You cannot directly filter SIP protocols while capturing. However, if you know the ["TCP"] port used (see above), you can filter on that one.
