John, Would you be willing to share the ATA that you are having success with? We always obtained results that were "okay", but nothing that was reliable enough for something like a medical clinic that sends a hundred faxes a day. Granted this may have a lot to do with the provider, but I'm still curious as to what you've had success with.
