Description: HH3C MIB for voice interface configuration managing analog FXS/FXO and digital voice ports on H3C gateways.

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 HH3C-VOICE-IF-MIB?

HH3C-VOICE-IF-MIB is an H3C proprietary MIB configuring general voice-interface parameters on H3C voice gateway equipment. Its interface configuration table covers comfort-noise generation (CNG), non-linear processing switch, input/output gain levels, echo-cancellation enable and delay tap length, and dial-timer intervals (inter-digit and first-digit timeout). As a configuration MIB it lets an administrator tune audio-quality parameters like gain and echo cancellation per voice interface, which are common levers when addressing a voice-quality complaint. It is deployed on H3C voice gateways with analog or digital voice interfaces. Engineers can download the HH3C-VOICE-IF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-VOICE-IF-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

H3C voice gateways

Monitoring Examples

An administrator adjusts hh3cVoiceIfCfgEchoCancelDelay for an interface reporting persistent echo, after confirming hh3cVoiceIfCfgEchoCancelSwitch is enabled but the delay-tap length doesn't cover the actual round-trip echo path.

What Can Be Monitored

voice interface gain, echo cancellation, and dial-timer configuration
