The value of this object will depend on the interface type as well as on the protocol and protocol version being used on this interface. Some references for possible cause values are given below.

What is callHistoryDisconnectCause?

This byte string encodes a network-level reason code for why the call ended, format varies by interface type. Engineers decode these values to distinguish normal disconnects from errors, aiding root-cause analysis. A value of '10' might mean 'normal call clearing'.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.21.1.4.3.1.6
snmpwalk -v2c -c public <target> DIAL-CONTROL-MIB::callHistoryDisconnectCause

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.10.21.1.4.3.1.6.1
snmpget -v2c -c public <target> DIAL-CONTROL-MIB::callHistoryDisconnectCause.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> callHistoryDisconnectCause.1
