isdnMibCallInformation

Module: ISDN-MIB

OID (symbolic): ISDN-MIB::isdnMibCallInformation

OID (numeric): 1.3.6.1.2.1.10.20.2.0.1

Node type: NOTIFICATION-TYPE

Description: This trap/inform is sent to the manager under the following condidions: - on incoming calls for each call which is rejected for policy reasons (e.g. unknown neighbor or access violation) - on outgoing calls whenever a call attempt is determined to have ultimately failed. In the event that call retry is active, then this will be after all retry attempts have failed. - whenever a call connects. In this case, the object isdnBearerCallConnectTime should be included in the trap.

Only one such trap is sent in between successful or unsuccessful call attempts from or to a single neighbor; subsequent call attempts result in no trap.

If the Dial Control MIB objects dialCtlNbrCfgId and dialCtlNbrCfgIndex are known by the entity generating this trap, both objects should be included in the trap as well. The receipt of this trap with no dial neighbor information indicates that the manager must poll the callHistoryTable of the Dial Control MIB to see what changed.

Examples

Send this trap to an SNMP manager — replace <manager> with the IP or hostname of your monitoring server (SNMPv2c):

snmptrap -v2c -c public <manager> '' ISDN-MIB::isdnMibCallInformation
snmptrap -v2c -c public <manager> '' 1.3.6.1.2.1.10.20.2.0.1

Listen for incoming traps on the manager host (-f keeps it in the foreground, -Lo prints to stdout — useful for testing):

snmptrapd -f -Lo -c /dev/null authCommunity log public

Example snmptrapd log entry:

zoo11-linux.zoo [UDP: [192.168.30.111]:49634->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (43901410) 5 days, 1:56:54.10
  SNMPv2-MIB::snmpTrapOID.0 = OID: ISDN-MIB::isdnMibCallInformation

SNMPv3 example:

snmptrap -v3 -l authPriv -u snmpv3user -a SHA -A "AuthPass1" -x AES -X "PrivPass1" <manager> '' ISDN-MIB::isdnMibCallInformation
