ethereal already supports MTP2/MTP3/ISUP so there is almost
everything in the ethereal. Possibly we would need an MTP1
dissector. Except for zero bit deletion this should be
simple. But if the card does this in hardware and delivers
SUs it would be simple to write an MTP1 dissector. I could
do that. This is all about dissecting which is done in

The other stuff which needs to be done is the sniffing
support. There you need to extend the libpcap to work
with the SS7 card. I have no idea how difficult this might
be, but it would definitely be great. Possibly someone
else on the list can provide more help on this topic?

Do you get some software with the SS7 card which allows
you to capture traffic and write it to a disk file. We
could add support for reading such files to ethereal.

Best regards

Hello everybody,
I was wondering is there any development in the direction of sniffing SS7 traffic from a real (septel) SS7 card, that does not utilize sigtran. Please share any information on ways to do that. Is this on the roadmap at all?
Best Regards
