7.1

Description (partial)

Symptom:

Not all customers are dns gurus or know what round robin means, much less how to configure it for visual voicemail in active-active cluster web service to work correctly.

Conditions:

Customer is setting up visual voicemail for CUC 7.1 complex configuration in active-active cluster. They read this in the doc here...

http://www.cisco.com/en/US/docs/voice_ip_comm/cupa/visual_voicemail/7.0/english/install/guide/cluster_failover.html#wp1055618

Create one Visual Voicemail service on the Cisco Unified Communications Manager server. Use the cluster DNS alias as the hostname in the following fields: 

-Service URL of the service 

-Default Value of the voicemail_server parameter 

When you use the Cluster DNS alias for the voicemail_server parameter, the Visual Voicemail application uses the Cisco Unity Connection servers in a round robin order. When a user signs in to the Visual Voicemail application, the Cisco Unity Connection server that is used automatically provides the hostname of the partner server to the Visual Voicemail application. The partner hostname is cached locally by the Visual Voicemail application and is used in failover scenarios when the original server is not available. 

This only states how the alias works via round robin. It doesn't state that round robin is needed and how to set it up in a voice domain on a Windows DNS server.
