Our vendor has installed a Unified (with Exchange) Unity system with Failover. The system is a Unity release 7.x.
The vendor placed the two Unity servers (accessing a single Exchange message store) in two different geographically diverse locations.
At our main data center (where our Exchange system is located), they placed our primary Unity server. The Failover server is located about 20 miles away (connected via fiber). This second server is configured as a fail over (not distributed messaging) and is homed back to the one Exchange system.
The documentation (Cisco Unified Communications Solution Reference Network Design (SRND), chapter 13) seems to indicate that the primary and fail over Unity servers should be co-located.
Our vendor is Cisco Gold rated but I have to question this configuration. Is something new to Unity release 7.x that provides a reason for a remotely located fail over server?
Make sure you meet the requirements outlined here:

otherwise we won't support your deployment
