environment is recommended (a.k.a. Utopia), which puts ancillary processes [including cluster-master; a.k.a.
-master] on the backup box:
High Availability (HA) configured properly as per these guidelines.
Service VRRPs (Virtual Router Redundancy Protocols) in group 1 - box1/box2
Management VRRPs + cluster-master in group 2 - box2/box1
Database preempted in isolated group (say group 10) - box2/box1
All other master services in their own isolated group (registration in group8, call-failover in group9, etc.) - box2/box1
fault-group and media-fault-group set to "0" (this keeps a failover from happening due to a SIP fault, as this causes less of a service blip, due to the lack of a need for a gratuitous arp from a VRRP interface)
Exceptions: Master-Services - accounting in same group as database if local accounting is enabled, auth in same group as service VRRP if the service VRRP is the only route to the external auth server (potentially the same case with directory if an external directory is used)
sip-dead-groups set to "1" (this should match the service VRRP group number - this causes a failover to occur if SIP faults 5x in 1 hour, which would mark the process as "dead" which keeps it from restarting. Failing over gives 5 more attempts to tolerate whatever is causing the fault)
