VoIP Availability Manager builds a data model of the discovered Cisco VoIP elements in its domain. The model represents the elements and their relationships.

Cisco Enablement Pack object classes lists the elements that VoIP Availability Manager discovers for Cisco and displays in its topology.

Table 1. Cisco Enablement Pack object classes




Provides call processing, call control, transfer, call routing functions other IP phone features. This class covers implementation of software in Call Servers, IP PBX or soft switch. Examples are: Cisco CallManager, Cisco Unity CallManager, or Cisco Unity Communications Manager.


A list of data, provided to a Call Manager, that contains information about the registered, rejected, and unregistered devices for the Call Manager.


Represents a Session between CallManager in the same group to provide CallManager status data.


Represents a collection of CallManagers that together implement a service. The multiple instances of the application are typically accessed in a fault-tolerant manner thereby providing application redundancy.

Composed of CallManager and member of VoipCluster.


A service that provides lightweight call processing, call control, transfer, and call routing functions to local media gateways during a primary Call Manager server failover.


For example, a discovered instance of the network service provided by the Cisco Survivable Remote Site Telephony (SRST) or Cisco CallManager Express (CCME) is modeled as an instance of the CallProcessor class.


A Computer Telephony Integrated application that integrates voice and data between the Call Manager and the client’s business application environment. Examples include the delivery of Caller ID information using a Personal Computer, and the ability to access voice mail using the Personal Computer.


A VoIP network service used to pass traffic between older

Public Switched Telephone Network (PSTN) systems and VoIP systems. This service may also supply media related services, such as music on hold or other softswitch features.


A VoIP network service used to establish a VoIP session.


A physical instrument that acts as a telephone using Voice over IP technology. An IP phone can transmit audio-only information or video and audio information.


A group of IP phones. IP phone groups correspond to topological objects that are vendor-specific. For Cisco, the group corresponds to a device pool of IP phones registered to the same call manager group or, for Cisco CallManager Express (CCME), the same call processor.The device pool is predefined by the Cisco system administrator.


A VoIP network service used to process media streams. Functions included are: decoding DTMF tones, bridging multiple media streams into a conference, playing announcements, processing VoiceXML scripts, speech recognition, text-to-speech, and recording audio.


A personal voice mailbox that stores messages for an individual owner or a general delivery mailbox that distributes broadcast messages to a list of individuals.


A VoIP application providing VoiceMail functionality accessed by the network end-user.


An application that provides a voicemail service for Cisco Unity, Cisco Unity Express, and Cisco Unity Connection devices.


An application that provides an end-user service, such as a service represented by the VoiceMailApplication or CTIService class. A discovered application other than voice mail or CTI is represented as an instance of the VoipApplication class.

An example is Cisco Emergency Responder application.


Represents the logical grouping which integrates the VoIPnetwork and voice services into a single entity. The cluster may consist of call managers, redundancy groups, other VoIP services, and computer systems.


A process that is part of a VoIP application or VoIP network service.


A logical VoIP endpoint.


An application that provides an essential network-connection service, such as a Cisco Publisher or a service.


A running software program that is part of a network service or application. Some processes are designated as critical for the well being of their application/service. A failure of a critical process results in its application unable to fully function.


A software package providing miscellaneous end-user functionality. For example, contact center applications, etc.
