Yes. But take into account that what that flag does is propagate the Reason header, that is, add it to the generated CANCEL if the *received* CANCEL already has one. I don't think that is your scenario. In your scenario OpenSIPS is the one sending the CANCEL with a Reson, right?

If the CANCEL is locally generated perhaps you could catch it in a local route and remove the header there... is that possible Vlad?
