Description: Manages VoIP gateway call configuration, codec selection, and session statistics on Ascend equipment.

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 ASCEND-MIBVOIP-MIB?

ASCEND-MIBVOIP-MIB is a proprietary Ascend MIB for managing VoIP gateway call configuration, codec selection, and session statistics. It exposes configuration objects for codec and call-routing policy alongside live session data such as active call count, codec in use, and call-quality-related statistics. Its monitoring role centers on software/session health: tracking active VoIP session counts, codec negotiation outcomes, and call statistics reveals whether the gateway's voice-processing software is handling calls cleanly or degrading under load. It depends on the underlying call-handling MIBs in this family (such as ASCEND-CALL-MIB) for the call legs that VoIP sessions ride on. It was deployed on Ascend VoIP gateways used by carriers and enterprises to bridge traditional telephony and IP networks. Engineers can download the ASCEND-MIBVOIP-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in ASCEND-MIBVOIP-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.

Ascend VoIP gateways

Monitoring Examples

An operator polls the VoIP session statistics objects to see current active call count and which codec was negotiated for each session, comparing that against the gateway's configured codec preference list. A rise in fallback to a lower-quality codec, or an increase in session-statistics error counters, indicates network congestion or a codec-negotiation problem affecting call quality. Session statistics are typically correlated with ASCEND-CALL-MIB call data to pinpoint whether a quality issue is voice-specific or trunk-wide.
