I think the OP's point is that "soft hangup ..." does not hang up one
of the channels successfully. I have seen this before, usually from
soft-phones that do not disconnect cleanly, or WiFi phones that lose
signal during a call.

Using rtptimeout and rtpholdtimeout settings in sip.conf seems to
improve matters, as does using more recent versions of asterisk - You
do not say what version you are running.
