That has never been a Unity requirement. Can you provide a link to that documentation?

Its under Setup Requirments

Setup Requirements

The following components are necessary to integrate Cisco Unity with multiple Cisco CallManager clusters:

Cisco CallManager servers (version 3.1 or later) configured as a cluster at each location

A network connection between the clusters

An H.323 voice gateway for each cluster to connect to the IP WAN or PSTN

An H.323 gatekeeper to provide call admission control

Cisco Unity 3.0 or later, set up and integrated with the clusters

IP WAN

That gatekeeper is completely unnecessary. In fact, that white paper leaves a lot to be desired. It doesn't do a very good job of describing how to configure Unity to work with the multiple clusters.

Yeah, that portion of the doc is attempting to shed some insight on designing VoIP networks with a WAN consideration. Even if you have a WAN in the VoIP network, a gatekeeper isn't a requirement. Gatekeeper or no gatekeeper, Unity would not know the difference.
