Description: Manages Sonus Networks softswitch CDR accounting service configuration and call detail record generation.

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 SONUS-ACCOUNTING-SERVICES-MIB?

SONUS-ACCOUNTING-SERVICES-MIB is a vendor-specific MIB from Sonus Networks (a VoIP softswitch/media gateway vendor) covering the accounting/CDR subsystem that logs call detail records. It exposes configuration of CDR generation mode and log destination, plus performance counters for call attempts, completions, failures, and busy-hour rates. Its monitoring value is largely software/service status: sonusAcctIntAcctState shows whether interim accounting is active, and counters like sonusAcctNumCallAttemptFailures and sonusAcctOutOfServiceReason reveal when the accounting or call-processing service is degraded or unable to log records. It is part of a broader family of Sonus MIBs (SONUS-SIP-SIGNALLING-MIB, SONUS-H323-SIGNALLING-MIB, etc.) sharing the sonusMib-2 tree, and does not stand alone from the switch's core call-processing state. It is deployed on Sonus GSX/PSX softswitches and media gateways in carrier and enterprise VoIP networks, and billing teams reference the SONUS-ACCOUNTING-SERVICES-MIB MIB definition when integrating CDR collection tools.

IPNetwork Monitor allows you to monitor SNMP objects defined in SONUS-ACCOUNTING-SERVICES-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

VoIP media gateway

Monitoring Examples

A billing/NOC operator would poll sonusAcctNumCallAttempts against sonusAcctNumCallCompletions and sonusAcctNumCallAttemptFailures to compute a real-time call success ratio, and watch sonusAcctBusyHourAttempts and sonusAcctCallAttemptRate for capacity planning. sonusAcctAvgCallDuration helps spot abnormal call patterns, while sonusAcctIntAcctState and sonusAcctGenerationMode confirm CDR generation is actually running as configured. A rising sonusAcctNumCallAttemptBlocked count alongside a populated sonusAcctOutOfServiceReason would flag that the accounting subsystem itself is blocking calls due to a fault.

What Can Be Monitored

call attempt/completion/failure counts
busy-hour call attempts
call attempt rate
average call duration
CDR generation/log destination state
out-of-service reason

How to Use in IPNetwork Monitor

Example using sonusAcctNumCallAttempts OID:

Select a Sonus Networks softswitch, VoIP media gateway (CDR accounting/call-attempt statistics) as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type sonusAcctNumCallAttempts into the Find box to locate it in the OID tree, then select it and click OK. The total Number of Call Attempts since last reboot. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter64-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
