Description: Monitors SIP endpoint registration status and statistics on ADTRAN AOS devices.

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 ADTRAN-AOS-SIP-REGISTRATION?

This is a vendor-specific MIB from ADTRAN for devices running its AOS (Adtran Operating System) firmware, used to monitor SIP trunk/endpoint registration status toward a SIP registrar. It exposes alarm objects identifying a specific SIP trunk and its registrar, a timestamp of the alarm event, and a trap definition for registration failures, alongside conformance/compliance group definitions. Functionally it monitors software/service status rather than physical hardware — specifically whether a configured SIP trunk is currently registered with its upstream registrar, which is critical to VoIP service availability. It is a small, focused MIB typically used together with ADTRAN's broader AOS system and voice MIBs for full device and call-quality visibility. It's typically deployed on ADTRAN enterprise routers/gateways that provide SIP trunking to a service provider, where loss of registration causes an outage for all inbound/outbound calls. Network engineers evaluating or troubleshooting this functionality can download the ADTRAN-AOS-SIP-REGISTRATION file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ADTRAN-AOS-SIP-REGISTRATION. 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

  • ADTRAN AOS-based router/VoIP gateway

Monitoring Examples

A monitoring system would subscribe to adSipRegistrationTraps and inspect adSipTrunkRegistrationAlarmTrunkIdentity and adSipTrunkRegistrationAlarmSipIdentity to identify which SIP trunk deregistered, cross-referencing adSipTrunkRegistrationAlarmRegistrar to see which upstream registrar rejected or dropped the registration. adSipTrunkRegistrationAlarmTimestamp records exactly when the deregistration occurred, letting an admin correlate it with a WAN outage or registrar-side maintenance window. Repeated registration alarms on the same trunk typically indicate a persistent SIP trunking or authentication problem with the carrier.

What Can Be Monitored

  • SIP trunk registration status
  • registrar identity
  • registration failure timestamp
  • registration alarm/trap events
