Chapter 3 Cross-Server Logon, Transfers, and Live Reply
Cross-Server Logon
Although cross-server logon will transfer the calls to the home server in the above cases, doing so for a
large number of subscribers will increase the load on the Cisco Unity servers. Therefore, when a
subscriber account is moved to another Cisco Unity server, the subscriber phone still must be configured
to call the home server.
Prerequisites: Enabling Cross-Server Logon
All of the Cisco Unity servers must be configured for Digital Networking as described in the
“Setting Up Digital Networking” section on page 2-3.
The cross-server features are supported for integrations with Cisco Unified Communications
Manager (CM) (formerly known as Cisco Unified CallManager), integrations with phone systems
through PIMG/TIMG units, and/or integrations with Cisco SIP Proxy Server (CSPS). Integrations
with phone systems through voice cards are not supported. See the “Phone System Considerations
for Cross-Server Features” section on page 3-2 for more information.
Task List: Enabling Cross-Server Logon
Use the following task list to enable cross-server logon. The cross references take you to detailed
procedures.
1. Verify that all of the networked Cisco Unity servers are configured to be in the same dialing domain,
as described in the “Customizing the Primary Location” section on page 2-6.
2. On the destination Cisco Unity servers, verify that the Cisco Unity call routing rules are set to route
calls to the Opening Greeting call handler. (This is the default when Cisco Unity is initially
installed.) See the “Verifying That Call Routing Rules Are Set to Route Calls to the Opening
Greeting” section on page 3-6.
3. On the Cisco Unity server that you have designated to handle cross-server logons (the server that
subscribers will be calling), enable cross-server logon and enter the pilot numbers of the destination
Cisco Unity servers. See the “Enabling Cross-Server Logon and Entering the Pilot Numbers of
Destination Cisco Unity Servers” section on page 3-7.
4. Test the cross-server logon functionality. See the “Testing Cross-Server Logon” section on page 3-7.
Note Subsequently, if a new Cisco Unity server is added to the dialing domain, you will have to add the pilot
number of the new server to the Network > Dialing Domain Options page.
Procedures: Enabling Cross-Server Logon
Verifying That Call Routing Rules Are Set to Route Calls to the Opening Greeting
Do the following procedure on each of the destination servers. For failover systems, do the procedure on
both the primary and secondary servers.
To Verify That Call Routing Rules Are Set to Route Calls to the Opening Greeting
Step 1 In the Cisco Unity Administrator, go to the Call Routing > Direct Calls page.
