Max, I like to use sipscenario, written by Mr. Ray Elliot. Fantastic piece of call trace plotting perl software. It requires that: 1) You have the ability to gather a ethereal trace. 2) You can install the perl code. 3) You learn how to use the perl code to identify specific calls in the trace you wish to plot. If the trace.w file contains just the call you are interested in, you can just run the perl script and plot the whole trace. 4) You can use a text editor to view the trace, or, you can use a html browser. Here is a link to the code, there may be newer ones out there: http://lists.iptel.org/pipermail/serusers/2003-July/002125.html -g On 6/5/06, Max Clark <max.clark(a)gmail.com> wrote: -- Greg Fausak greg(a)thursday.com
