Standby Redundancy
•Both Cisco Unity servers must appear on the Cisco Unity Supported Platforms List at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/products_data_sheets_list.html and must belong to the same platform overlay.
•There must be a connection of 100 Mbps between the primary and secondary Cisco Unity servers.
•The network must meet the requirements listed in the “Network Requirements” section of System Requirements for Cisco Unity Release 5.0 at http://www.cisco.com/en/US/docs/voice_ip_comm/unity/5x/requirements/50cusysreq.html.
•If the Cisco Unity servers are being installed into an existing forest, both data centers must have one or more DC/GCs and one or more DNS servers.
If the Cisco Unity servers are being installed into a new forest, both must be DC/GCs in the same Active Directory domain.

•The SQL Server 2000 services MSSQLSERVER and SQLSERVERAGENT on both Cisco Unity servers must be configured to log on as the same domain account, and the account must belong to the Local Administrators group on each server. SQLSERVERAGENT on the primary server must be able to log on to SQL Server on the secondary server by using Windows NT authentication.
