Hm... not working for me:
I dial a non-existing PSTN number via Nikotel:

    -- Got SIP response 404 "Not Found" back from 63.214.186.6
    -- SIP/nikotel-out-phil-b8e1 is circuit-busy

However CAUSECODE remains empty (checked thru NoOp({CAUSECODE}).

If instead I use HANGUPCAUSE I get "5" as return; that looks better as 
this - correctly - translates 404 into "unallocated".

Cheers, Philipp
