IP Availability Manager discovers the underlying transport domain in the VoIP network, monitors availability, and analyzes the network connectivity to identify the root-cause problems and impacts of connectivity failures. It exports network topology, problem, and impact information to the Global Manager, and exports VoIP-enabled device topology and status information to VoIP Availability Manager.
VoIP-enabled device topology includes signaling servers, call servers, media gateways, hosts, routers, switches, and nodes. Device status information consists of status changes associated with the VoIP-enabled device topology imported by VoIP Availability Manager.
A VoIP Availability Manager deployment may contain one or more IP Availability Managers. An IP Availability Manager instance may consist of just an IP Availability Manager process, or may consist of an IP Availability Manager and an IP Performance Manager or IP Server Performance Manager running as a single process.
