About the VoIP topology collection set

IP Availability Manager performs its discovery of network objects and also, with optional customizations, creates a VoIP topology collection from the discovered network objects for VoIP Availability Manager. It probes the SNMP agent of every device in the managed network for VoIP support.

IP Availability Manager stores the VoIP topology collection set in the VOIP_TopologyCollection::VOIP-System-TopologyCollection object.
