Description: Provides interface-level VoIP management objects for H3C/3Com gateways, including per-interface call statistics, codec negotiation, and media stream parameters.

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 A3COM-HUAWEI-VOIF-MIB?

A3COM-HUAWEI-VOIF-MIB is an H3C proprietary MIB configuring general voice-interface parameters on H3C voice gateway equipment. Its configuration table, keyed by port/group number, records comfort-noise-generation enable, input/output gain, echo-cancellation switch and delay, PLAR (Private Line Automatic Ringdown) number, description, status, calling/called-number substitution rules, and associated sub-line. As a configuration MIB it lets an administrator confirm a voice interface's echo-cancellation and gain settings match the intended call-quality target. It is deployed on H3C (3Com/Huawei) voice gateway equipment. Engineers can download the A3COM-HUAWEI-VOIF-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in A3COM-HUAWEI-VOIF-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 (3Com/Huawei) voice gateway equipment

Monitoring Examples

An administrator checks h3cVoIfCfgEchoCancelSwitch and h3cVoIfCfgEchoCancellDelay on a voice port reporting echo complaints, to confirm echo cancellation is enabled with an appropriate delay setting.

What Can Be Monitored

voice interface echo-cancellation and gain configuration
