You did not specify for which version of Asterisk.  I am assuming at least
v1.8.

I think you are wanting the CALLEDTON channel variable.  It is set for
incoming ISDN calls to the lower 7 bits of the Q.931 type-of-number/numbering-plan
octet.  The CALLERID(dnid-num-plan) should have the same value but I cannot
find any code setting the value.  (Looks like I missed setting that value. :))
I could only find the value being set to the CALLEDTON channel variable.
