I am using ethereal for MGCP traces. I was wondering, if I can filter
MGCP messages based on content of the MGCP message.
That depends on the part of the content you want to check. If you click on the "Filter:" button when constructing a filter to filter the display, you'll get a dialog box with an "Add Expression..." button; in the color filter dialog, the "New..." button will pop up a dialog box with that button as well. If you click on the "Add Expression..." button, you'll have a scrolling list of protocols - search for "MGCP" and click on the "[+]" box to open up the list of filterable fields for MGCP.
For example : - I want to see MGCP packets with Response code other than 
200 and 100 in color other than black.


From a quick look at the code, it appears that the filter

	mgcp.rsp.rspcode != 200 && mgcp.rsp.rspcode != 100

will check for that.
