I was just reading an older post from March so
I couldn't respond to it directly.

SCCP can carry ISUP traffic although it is commonly
directly on top of MTP3.

In addition there must be a lot of SCCP traffic
using SCCP for standard A interfaces, between
BSCs and MSCs.

For example
IOS (not CISCO IOS), IS-634-A in North American
ANSI/IS-41 based systems or BSSAP (GSM 08.06)
for the GSM A interface.  UMTS RANAP will also
use SCCP.

The only way you will be able to see the INAP data
nicely is if someone writes an Ethereal dissector for it.

You cannot change the SSNs.

If you know the SSN for INAP the TCAP dissector could
be changed to at least dissect the TCAP portion.

I can do it if you want.
