Description: Monitors H.323 and SIP protocol-level performance statistics on AudioCodes gateways, including registration rates, call setup success rates, and signaling message counters.

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 AC-PERFH323SIP-GATEWAY-MIB?

AC-PERFH323SIP-GATEWAY-MIB (module identity acPerfH323SIPGateway) is an AudioCodes vendor-specific performance MIB that tracks H.323/SIP call-signaling statistics on AudioCodes media gateways and media servers (Mediant/Stretto product lines, IPmedia 2000). Its acPerfTel2IP and acPerfIP2Tel branches each expose parallel counters for telephony-to-IP and IP-to-telephony call directions — attempted calls, established (connected and voice-activated) calls, busy/no-answer/no-route/no-capability-match failures, fax-attempt/fax-success counts, and total call duration — organized under acPerfH323SIPGWCalls as part of the module's broader acPerformance tree, which per its description also covers IVR, blind-call-transfer, conferencing, and test-trunk performance groups. This makes it useful for monitoring gateway call-completion health in both directions, distinguishing routing failures (no-route/no-capability-match) from destination-busy or no-answer conditions, and tracking fax success rates separately from voice calls. It depends only on SNMPv2-SMI base types (Counter32, Gauge32) and AudioCodes' own enterprise OID registration (audioCodes/acPerformance), and operators tuning AudioCodes gateway alerting commonly reference this MIB's AC-PERFH323SIP-GATEWAY-MIB SNMP monitoring counters for call-quality dashboards.

IPNetwork Monitor allows you to monitor SNMP objects defined in AC-PERFH323SIP-GATEWAY-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

AudioCodes Mediant/Stretto media gateways and IPmedia media servers

Monitoring Examples

An operator polls acPerfTel2IPAttemptedCalls against acPerfTel2IPEstablishedCalls to compute a call-completion ratio, and watches acPerfTel2IPNoRouteCalls; a rising no-route count relative to attempted calls would indicate a dial-plan or routing misconfiguration on the telephony-to-IP leg of the gateway.

What Can Be Monitored

Tel-to-IP call attempt/established/failure counters
IP-to-Tel call attempt/established/failure counters
fax attempted/success call counters
no-answer/busy/no-route/no-match call failure breakdowns
total call duration counters

How to Use in IPNetwork Monitor

Example using acPerfTel2IPAttemptedCalls OID:

Select an AudioCodes Mediant/Stretto gateways 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 acPerfTel2IPAttemptedCalls into the Find box to locate it in the OID tree, then select it and click OK. It reports the number of Attempted SIP/H323 calls. 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 Counter32-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.
