Attached are a collection of tables from CISCO-CCM-MIB to provide additional information about Cisco Call Manager (not CME).
Specifically, the ccmTable which contains information about all the Call Managers in a cluster that the local Call Manager knows about and the ccmGatewayTable which provides information about all of the gateway devices that have tried to register with the local Call Manager.
These UnDPs should be applied to nodes that are Cisco Call Managers that have SNMP enabled on them. After you apply the UnDPs, edit the Node Tabular Universal Device Poller resource and check all of the options and select all rows to include all of the information in one resource (one resource for the ccmTable and another for the ccmGatewayTable).
Feedback greatly appreciated!
