Hi
Using length fields one could auto-detect the version of MTP3 (and possibly other standards such as ISUP and SCCP), provided that the packet is well formed.
However, when the packet is malformed (which is often the case when trouble shooting), then auto-detecting feature could be a cause of trouble. If a packet is detected as, say, ANSI, but really was a malformed ITU, then trouble could ensue.
In any case, I too had problems getting my first CAMEL trace to be detected correctly. I changed the SSN to 0-254 in the CAMEL preferences to get ethereal to read it as CAMEL.
I don't know how hard could it be to implement this, but what if , when viewing a packet, a little window would show the current (important) preferences to the user, just as a reminder of what he can change?
For instance, when viewing a TCAP trace, the window could show something like:
MTP3 standard: ANSI
SCCP standard: ANSI
TCAP SSN: 5-100
Just my 2 cents.
Best Regards
Javier Acuña
