VMware Smart Assurance discovery is the process of using VMware Smart Assurance ICIM class models to create a representation of the managed topology within the repository, or database, of a Domain Manager. For VoIP Availability Manager, data is collected from VoIP-enabled devices in the managed network to create instances of VoIP topology objects, their relationships, and their logical connections.

When a VoIP-enabled device is added to the managed network, VoIP Availability Manager performs discovery on the device to determine the VoIP topology objects associated with the device. When a VoIP-enabled device is removed from the managed environment and deleted from the topology, VoIP Availability Manager removes the device and all of its associated VoIP topology objects from the modeled topology.
