The flow of information among the components of a VoIP Availability Manager and Enablement Pack deployment proceeds as follows.

During discovery:

  • The IP Availability Manager performs discovery of routers, switches, and hosts, as well as VoIP devices, along with their physical and logical connectivity.

  • The IP Availability Manager groups the VoIP devices into a Topology Collection using deployment customization. This Topology Collection may be used to filter the devices monitored by VoIP Availability Manager based on customers’ organizational partitioning.

  • VoIP Availability Manager imports the VoIP device information from the IP Availability Manager, and uses that information as the foundation for its own discovery.

  • VoIP Availability Manager uses SNMP discovery probes to discover the VoIP specific elements.

  • After a successful discovery, VoIP Availability Manager creates a VoIP topology with relationships between the associated elements.

    During event processing:

  • The IP Availability Manager polls network elements and performs root-cause and impact analysis for the IP domain.

  • The IP Availability Manager sends notifications to the VoIP Availability Manager.

  • VoIP Availability Manager, in conjunction with the installed Enablement Pack(s), uses SNMP Instrumentation to monitor the health of the VoIP topology and generate appropriate symptoms and events.

  • VoIP Availability Manager includes a built-in SNMP trap receiver which listens for VoIP related traps. Traps generated by the monitored devices and forwarded to the VoIP Availability Manager are processed to set the state of the referenced component. Note that the traps must be enabled and their destinations set.

  • VoIP Availability Manager imports the performance oriented data collected by VoIP Performance Manager to enrich the VoIP Availability Manager topology with information from traps sent at regular intervals.

  • The Global Manager receives notifications from the IP Availability Manager and the VoIP Availability Manager for presentation to network operations personnel.
