I'm using 1.8.0 and it seems the SCCP dissector is never decoding the SCCP Address Indicator h-Bit. Under normal circumstances this should (afaik) be set to '0' but by accident I stumbled into a situation where the h-bit was actually set to '1', breaking things. From the packet-byte window is could be seen, but it would be terrible convenient if the h-bit would also be decoded too. Can this be added or is there a reason not to do this?
(I assume you mean the "reserved for national use" bit in the AI.)
Hmmm, yeah, I guess that was just an oversight (and here I am usually preaching about displaying reserved/spare fields)...
I added decode of that bit (for non-ANSI configurations; the bit is used--and decoded--in ANSI) in r43590. (This change will appear in the automated builds in a few hours and the next development version--i.e., 1.9.0 and later).
