Node type: NOTIFICATION-TYPE

Description: A SIP phone unregistration notification is generated when the number of SIP phone unregistrations have exceeded the threshold. The number of currently registered SIP phones is provided here by csrstSipPhoneCurrentRegistered object as a reference such that if csrstSipPhoneCurrentRegistered falls below csrstSipPhoneUnRegThreshold, a notification will be generated to indicate that the number of unregistered SIP phones has crossed the threshold.

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> '' CISCO-SRST-MIB::csrstSipPhoneUnRegThresholdExceed
snmptrap -v2c -c public <manager> '' 1.3.6.1.4.1.9.9.441.0.3

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]:53440->[192.168.30.10]:162]:
  DISMAN-EVENT-MIB::sysUpTimeInstance = Timeticks: (198846656) 23 days, 0:21:06.56
