[asterisk-ss7] different ss7_calling_nai for CICs on same E1

[joseph mpora]

Hullo,

We have 1 E1 from a telco that they would like us to use for both
local and international traffic.

I currently have ss7_calling_nai set to national and this works fine
for local calls. Now they would like us to use CIC 17-31 for
international calls on the same E1.

Is it possible to have ss7_calling_nai as national for CIC 1-16 and
ss7_calling_nai as international on the same E1?
