[asterisk-dev] Forwarding of SIP response codes

it seems that SIP response codes are not forwarded thoroughly back to an
SIP-UA. This happens for example in a call setup like this:
SIP-Phone -> Asterisk -> SIP-Gateway
If the SIP gateway answers 404 asterisk converts this into 503 and sends
it to the calling SIP phone. The additional header
"X-Asterisk-HangupCause: Unallocated (unassigned) number" is nice but
does not help the SIP phone to display the correct hangup cause.
Is there any way to just forward the original response code? Did I miss
something in the documentation to get this working?
