With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
Cisco Call History Iec Index
This object is used to index one or more IECs in the context of a single call. In most cases there will only be one IEC when a call fails. However, it is possible for the software processing the call to generate multiple IECs before the call ultimately fails. In that scenario, there will be multiple entries in this table related to a single call (cCallHistoryIndex) and this object will serve to uniquely identify each IEC.
