TNG has a ratebook for VOX. We do not have a ratebook for each package VOX has available.
Required: At least TNG Version 1.0.7.0, to update to this version your TNG must expire after 01 May 2010.
TNG has a Custom ratebook feature. You can install the VOX ratebook as your default and then use Custom rates to configure a custom ratebook for your VOX package.
