Description: Defines Lucent SIP trap notifications for registration failures and call signaling fault events.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is SIP-TRAP-MIB?

SIP-TRAP-MIB is a Lucent module defining SNMP trap notifications for Session Initiation Protocol events, focused on registration failures and call-signaling fault conditions. It belongs to the VoIP/telephony fault-management category and, unlike statistic-heavy MIBs, its content is centered on notification definitions rather than polled counters. Its monitoring value is about software/service health: alerting operators in near real time when SIP user registration fails or when a call setup/signaling error occurs, which are key indicators of a SIP proxy or gateway's operational health. It depends on SIP protocol concepts (and likely shares textual conventions with a SIP-TC-style module) for representing SIP-specific error and entity information in trap variable bindings. It is deployed on Lucent SIP-capable voice gateways or softswitches handling VoIP call signaling. Engineers can download the SIP-TRAP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SIP-TRAP-MIB. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Lucent SIP-capable voice gateways/softswitches

Monitoring Examples

An operator's NMS would subscribe to the traps defined in this MIB to get immediate alerts when a subscriber's SIP registration fails repeatedly, which could indicate a misconfigured endpoint or an authentication problem on the SIP server. Similarly, a call-signaling fault trap firing during call setup would flag a proxy or gateway issue affecting active calls, prompting investigation before a broader outage. Because the module is trap-oriented, monitoring is primarily event-driven rather than based on a polled table.

What Can Be Monitored

  • SIP registration failure events
  • call signaling fault events
  • SIP trap notification occurrences
