Couple things.
1. Bulk Import was never on ciscoUnityTools.com for download - CUBI was only avaialble with the installation of Unity (it's wound around the DB tool's for each release too tightly to be done as a stand alone install).
2. If you ever wonder "is this missing" you can always get to the old site by going to www.LindborgLabs.com.
I'll leave the old site up for at least a year just in case something was missed.
