• Heartbeat state changes appear in CVP logs as UnreachableDestinationTable add/remove entries and endpointUnreachableClear events. in context
• Technote 218122 states a default of 3 attempts before a CVP heartbeat destination is marked down. disputed in context
• CVP keeps failed destinations in an unreachable destination table; the DsUnreachableDestinationTableTimer default is 180 seconds. in context
• CVP SIP server group heartbeats use the SIP OPTIONS method as a ping to learn endpoint status without placing a call. in context
• Per a CVP 12.5 technote, the Call Server diagnostic page at https://<callserver>:8000/cvp/diag should show the SIP, ICM and IVR states as In Service. in context
• The listen port for the Call Server SIP Service and the listen port for SIP Server Group heartbeats must differ, because they are separate processes and cannot share a port. in context
• Per a CVP 12.5 technote, when heartbeats are not enabled an unreachable endpoint stays in the Call Server's unreachable destination table for 3 minutes before it is tried again. in context
