PS4, Line 269:        "When receiving a TCAP Continue/End/Abort message where 
no ASP can be assosiated (either via session tracking or by TCAP range for 
dtid). How should this message handled.\n"
"associated"
"message handled" -> "message be handled".

PS4, Line 547:  const char *tcap_unroutable_str = 
get_value_string_or_null(osmo_ss7_as_tcap_unroutable_vals,
This only makes sense in SS7_AS_TCAP_UNROUTABLE_ROUTE_FALLBACK case afaiu, so 
better move this lookup inside the switch case.

Not sure what you mean.

PS4, Line 469:  struct osmo_mtp_transfer_param new_mtp = {};
since you are copying orig_mtp just below, there's no need to zero-initialize 
the struct here.

elsewhere

 :
PS4, Line 506:          /* Message is handled and will be routed elsewhere */
afaiu this comment is misleading, since case "rc" is actually an error and the 
message is not being routed?
