Hello,
the respective patch was done to fix generating CDRs on local BYE. Maybe
cnxcc is locking slots as well, I am not familiar with the module at all.
Perhaps the best is to change the mutexes to be re-entrant, to avoid
such conflicts between dialog and upper layer modules relying on it. I
will push a patch for it.
Cheers,
Daniel
