Talking about libss7/chan_dahdi the Nature of Address Indicator in the IAM (called party number and calling party number) are show exposed to variables by chan_dahdi at this time. Nahuel (friend of mine) will send to you in a few minutes a patch to do it. This will expose SS7_CALLED_NAI and SS7_CALLING_NAI containing the definition in Q763 3.9b:

1 - subscriber number (national use)
2 - unknown (national use)
3 - national (significant) number
4 - international number
5 - network-specific number (national use)

Best regards,

Gustavo

Besides the destination number plan, there is a Nature of Adress Indicator. If _should be_ set in all calls.
Do you need some traces as examples?
