when you say "guarantee", you mean for all machines that handle H.248 traffic?
If yes then I think the answer is would be No.
That's way the machines that I am working on are doing it and of course for the specific interface.
These are Gateways that inlcude DSPs which convert voice traffic coming from TDM lines to IP.
As far as I know the termination IDs depend on the traffic type that the GW is handling on the TDM side.
TDMs15c4f1/1/6/3/25 for trunking GWs
port_1, port_2 for PSTN
port_PA0014/B1 for ISDN PRI etc, etc, ....
in the filter options I also found the _expression_ h248.termList
but I don't how to use it.
any ideas on that one?
thanks in advance :)))

Unfortunately, nobody can possibly know that, because the Wireshark filter mechanism doesn't support it.
Is there any guarantee that megaco.termid is of the form "port_N", for some numerical value N?
