not sure its a violation to have a reason header in a 18X response. what the carrier is saying in this case is... here is a 183, bring up media... BUT here is a REASON ( with q850 most probably ) you can conditionally hangup now.. EG. 183 with Q850 code 1 ( Unallocated number ) now if you dont hangup, the carrier plays a recorded announcement saying "unallocated number" key here is, you can decide if you want the recording, or to just hangup when you get the reason.
