Hi,

The patch is to the graph_analysis functionality, that is generic and not
tied to any specific application. The only one currently using it is the
VoIP calls list, and implementing this for tethereal is difficult, because
you need to choose which calls you want to graph, and the choice is not
trivial -e.g. for SIP calls it depends on the call id, while for ISUP it
depends on the combination of spc, dpc, cic and time-, so I don't know how
to implement it as a command line parameter. One option would be "plot every
call that is in the file".

I'm currently trying to implement a "generic" flow graph function that might
be easier to use from tethereal. If I get it working it then the VoIP possibility 
would probably offer little advantage.
