Media Gateway Control Protocol (MEGACO/H.248.1)

MEGACO is used to control a Media GAteway in a VoIP system, MEGACO can be Text or Binary encoded.


Protocol dependencies


a TPKT header must be included.

Example traffic

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


The MEGACO dissector works for TEXT encoding of the protocoll if EOL is used as SEParator. 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 PROTO 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 PROTO display filter fields can be found in the [ display filter reference]

Capture Filter

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