i think so.

in theory yes, but when i implemented this, there was a patch to tm
module that assigned final reply to sip_msg structure field called
"final_reply".  there is still no such field in current rel_0_9_0
sip_msg structure and i didn't see anything else either that could give
access to the reply contact header.

in summary: without access to reply message, there is no way to
implement this functionality.
