Wireshark-dev: [Wireshark-dev] VoIP call analysis

Hi,

I'm looking at voip_calls.c and there is a voip_protocol_name array
that contains, among others, SCCP, BSSMAP and RANAP.

How does this work for a with the following partial stack:

BSSMAP or RANAP
SCCP
M3UA
...

?

I tried out one of my traces with SCCP and it sort of works.
Was it meant to be used with the above or for some other kind
of protocol layering ?
(I thought only "A-interfaces" used connection-oriented SCCP.)

I say it only sort of works because SCCP can't determine a
call state or even imply a call is taking place.

Should I just ignore the SCCP code eventhough IOS 5 is
carried on it ?

Thanks.
