During the second phase of the discovery process, imported devices are probed to identify VoIP topology information. Only devices re-discovered in IP Availability Manager since the last VoIP Availability Manager discovery are scheduled for probing. You can change this default probing behavior by modifying the DiscoverAll parameter as described in the VMware Smart Assurance VoIP Availability Manager Configuration Guide. At the end of the probing, instances of VoIP-specific objects are created in the VoIP Availability Manager repository.
During this phase of the discovery process, VoIP Availability Manager creates instances of the classes identified in Initial topology added to the VoIP Availability Manager repository. The hierarchy of the classes is shown in Appendix A, “VoIP Data Model.”

Cisco |
Network services |
||
CallProcessor |
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.
Note:
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. |
Cisco |
GatewayService |
An application that converts voice and fax calls between the PSTN and an IP network.
Note:
For example, a discovered instance of the network service provided by the Nortel Voice Gateway Media Card (VGMC) is modeled as an instance of the GatewayService class. |
All |
