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 VOICE-OPT-MIB?

VOICE-OPT-MIB is a private MIB (enterprise OID 449, Cisco cdx6500 product family) configuring voice port parameters for DSPM/E&M, DSPM/FXS, DSPM/HC, and DSPM/SM voice interface cards. Its port table records interface/signaling type, E-lead filtering, hybrid FXS/E&M mode, signaling mode/control, digit-collection count, ring count, PCM mode and compression rate, DSI control, smoothing delay, echo control/return-loss, transmit input/receive output signal levels, fax support/rates, voice-band detection, and auto-call mnemonic. As a configuration MIB it lets an administrator confirm a voice port's echo-control and signal-level settings match the intended PBX/carrier interconnection. It is deployed on cdx6500-family voice-gateway equipment. Engineers can download the VOICE-OPT-MIB file directly to load it into their MIB browser.

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

  • cdx6500-family voice-gateway equipment

Monitoring Examples

An administrator checks cdx6500VoiceCfgEchoControl and cdx6500VoiceCfgEchoReturnLoss on a voice port reporting echo complaints from callers, to confirm echo cancellation is enabled with appropriate return-loss settings.

What Can Be Monitored

  • voice port signaling, echo control, and signal-level configuration
