I have mostly the same problem.  When the softphone behind my NATing
proxy hangs up, the BYE message goes through the proxy.  However, when
the outside phone hangs up, my proxy never sees the BYE message, as
though it was never issued.

My configuration file calls record_route() only for the INVITE action.
Is it sufficient in regard to the fact the BYE will be send to the
IP address in the Record-Route header ?

My configuration file contains:
% if (method == "INVITE") {
% 	record_route();
% 	force_rtp_proxy("r");
% 	t_on_reply("1");
% }

Thank you.
