Avaya Definity Gx/PBXLink Integration Guide for Cisco Unity 4.0

Integrating a Secondary Server for Cisco Unity Failover

The Cisco Unity failover feature enables a secondary server to provide voice messaging services when the primary server becomes inactive. For information on installing a secondary server for failover, refer to the applicable Cisco Unity installation guide, available at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html.

For information on failover, refer to the Cisco Unity Failover Configuration and Administration Guide. The Domino version of the guide is available at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/fail/fail401/dom/index.htm. The Exchange version of the guide is available at http://www.cisco.com/univercd/cc/td/doc/product/voice/c_unity/fail/fail401/ex/index.htm.

Requirements

The following components are required to integrate a secondary server:

Phone System

•A data splitter unit to split the single serial cable from the first PBXLink box (which connects to the Cisco Unity servers) into two serial cables.

•Two additional RS-232 serial cables (to be used with the serial cable that was connected from the PBXLink box directly to the primary server when it was integrated with the phone system). With these three serial cables, connect one serial cable from the SMDI port in the first PBXLink box to the data splitter unit; connect the second serial cable from the data splitter unit to the serial port on the primary server; and connect the third serial cable from the data splitter unit to the serial port on the secondary server.

Cisco Unity Server

•One secondary server for each primary server installed and ready for the integration, as described in the applicable Cisco Unity installation guide and earlier in this integration guide.

•The applicable cable configuration for each analog voice messaging port to simultaneously connect the phone system to the corresponding ports on both the primary and the secondary servers. For example, connect port 1 on the phone system with both port 1 on the primary server and port 1 on the secondary server.

•A license that enables failover.

Integration Description

The phone system uses PBXLink boxes to send call information to the primary and secondary servers. The analog voice messaging lines from the phone system provide voice connectivity to the primary and secondary servers. Figure 3 shows the required connections.
