Any reason you're using a deprecated module? you should be using
mod_freetdm and not mod_openzap. I think it's been 2 years since we renamed
openzap to freetdm and did all new development on freetdm. I don't
particularly remember if the issue you mention is fixed, but before I would
even look at the logs to see if there is an issue indeed you need to
upgrade to FreeTDM.
