Hi,
I made some fixes regarding some similar cases - BYE not being
transmitted on the other side, but only in trunk now. I will make the
backport now and let you know when it is done.

I've setup several OpenSIPS proxies (keeping track of
dialogs,acc,etc.) behind a OpenSIPS B2BUA (to implement topology
hiding - nothing else).
I'm currently using version 1.6.3 on both the proxy & b2bua. I
updated the b2bua modules from svn yesterday.
Certain dialogs "hang" because of how the B2BUA handles an
inappropriate response to an INVITE in a never-established (canceled)
dialog coupled with the proxy establishing a dialog after a CANCEL
has been processed.
After the initial call attempt is canceled, the upstream carrier
responds with a 200 OK to the INVITE. The B2BUA sends that back to
the OpenSIPS proxy. The OpenSIPS proxy creates a dialog even though
the INVITE has been canceled. Soon afterwards, a BYE is received
from upstream but the B2BUA does not send that back to the proxy. As
a result, the dialog hangs (until the timeout is reached). I've
tried to show the call flow below:
