Module: DIAL-CONTROL-MIB
OID (symbolic): DIAL-CONTROL-MIB::callHistoryTableMaxLength
OID (numeric): 1.3.6.1.2.1.10.21.1.4.1
Node type: OBJECT-TYPE
Type: INTEGER

Description: The upper limit on the number of entries that the callHistoryTable may contain. A value of 0 will prevent any history from being retained. When this table is full, the oldest entry will be deleted and the new one will be created.
What is callHistoryTableMaxLength?
This number specifies the maximum calls to keep in the historical record; operators can adjust it. Engineers set this to balance storage capacity against how much call history they need for troubleshooting and billing. Setting it to 10,000 means the system keeps the 10,000 most recent calls.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.10.21.1.4.1 snmpwalk -v2c -c public <target> DIAL-CONTROL-MIB::callHistoryTableMaxLength
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.10.21.1.4.1.1 snmpget -v2c -c public <target> DIAL-CONTROL-MIB::callHistoryTableMaxLength.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.10.21.1.4.1.1 i <value>
