Got your log. Same case, but not quite. In your case the UA which
offered QOP did not send "any" authorization header in BYE. This is a
UA problem, not OpenSBC. Your UA should have sent a new authorization
header to update the previous authorization send in the INVITE
challenge. OpenSBC does not participate in mid dialog request
authentication except acting as a relay. It is also impossible for
OpenSBC to reproduce the QOP state without knowing the exact password
used to produce the original response. If OpenSBC "CAN" do this, then
QOP is in big trouble for obvious reasons.
