SRST Traps
SRST Traps
SRST traps are SNMP traps, which are unsolicited notifications of an unusual or a catastrophic system
event sent to the system administrator.
SRST traps or alerts are sent for the following:
•
Notification (alarm/trap): SRST SCCP port is down.
•
Threshold (trap and event correlation) on phones registering back and forth between CM and SRST
router due to flapping WAN link.
•
Threshold (trap and event correlation) on phones registering back and forth between SIP
server/proxy and SIP SRST router due to flapping WAN link.
Note
Send traps by modem or ISDN dial backup links to a secondary NMS when the primary NMS is down.
(Do this through the configuration in the SRST router.)

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.
