Session Initiation Protocol (SIP)

Session Initiation Protocol (SIP), is an application-layer control (signaling) protocol for creating, modifying, and terminating sessions with one or more participants. These sessions include Internet telephone calls, multimedia distribution, and multimedia conferences. IETF Charters related to SIP can be found here: [ SIP] [ SIPPING]


XXX - add a brief description of SIP history

Protocol dependencies

Example traffic

XXX - Add example traffic here (as plain text or Ethereal screenshot).


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

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.

Display Filter

A complete list of SIP display filter fields can be found in the [ 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.
