Disable discovery and topology synchronization in VoIP Availability Manager

By default, the VoIP Availability Manager connects to the configured underlying IP Managers to fetch initial topology for VoIP Availability Manager discovery. This functionality needs to be disabled on both the Active and Standby VoIP Availability Managers in a failover deployment before starting them.

The Failover Manager determines the VoIP Availability Manager where the topology synchronization and discovery is enabled. Discovery or topology synchronization is always enabled on the Active VoIP Availability Manager and disabled on the Standby VoIP Availability Manager.

For both Active and Standby locations, use the following steps to disable discovery or topology synchronization in VoIP Availability Manager:

In the installation area where VoIP Availability Manager is running, go to the BASEDIR/smarts/bin directory and open the bootend.conf file for VoIP Availability Manager. Type:
```
               ./sm_edit conf/voip/bootend.conf
            
```

Navigate to the following section in the bootend.conf file and change the value of suspendTopologyManager from False to TRUE.

ICF_TopologyManager::ICF-TopologyManager {
# suspendTopologyManager
# Suspends all topology manager operations
# Set this to TRUE if you are using the VoIP Server
# in a failover configuration
# Default value is FALSE
    suspendTopologyManager = TRUE
}

Save the file and exit.
