Description: HH3C MIB for active voice call monitoring tracking ongoing call sessions on H3C voice-enabled routers.

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-CALL-ACTIVE-MIB?

HH3C-VOICE-CALL-ACTIVE-MIB provides real-time visibility into currently active voice calls on H3C voice-enabled routers and gateways, covering both traditional telephony and VoIP call legs. It exposes active call tables with connection identifiers, call duration split by voice/fax/total transmit time, codec (coder type) in use, and fax page counts for the general call table, plus a parallel VoIP-specific active call table. Its core monitoring purpose is software/service status of the voice subsystem: tracking active call counts, durations, and codec selection reveals whether calls are being set up and torn down normally, whether fax relay is functioning, and whether an unusually long-duration or stuck call entry indicates a signaling or media-path fault. It typically works alongside other H3C voice MIBs (e.g., call history/statistics MIBs) and standard telephony signaling protocols underlying the call legs. It is deployed on H3C voice gateways and multiservice routers handling PSTN, VoIP, or T.38 fax-over-IP traffic in enterprise or carrier voice networks. Network engineers evaluating or troubleshooting this functionality can download the HH3C-VOICE-CALL-ACTIVE-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in HH3C-VOICE-CALL-ACTIVE-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 gateway/router

Monitoring Examples

An administrator would poll hh3cVoiceCallActiveTable for hh3cVoCallActiveConnectionId, hh3cVoCallActiveTxDuration, and hh3cVoCallActiveCoderType to see live call count, duration, and codec mix on the gateway. A hh3cVoCallActiveFaxTxDuration or hh3cVoCallActiveImgPageCount entry that stalls mid-transmission would indicate a failed fax relay session, while checking hh3cVoiceVoIPCallActiveTable's hh3cVoVoIPCallActiveConnectionId lets an operator separately confirm the VoIP call legs are active and progressing normally.

OIDs

OID symbolic	OID numeric	Type	Access	Description
hh3cVoCallActive	1.3.6.1.4.1.25506.2.39.15			This MIB file is to provide the definition of voice call active record information.
hh3cVoiceCallActiveObjects	1.3.6.1.4.1.25506.2.39.15.1
hh3cVoiceCallActiveTable	1.3.6.1.4.1.25506.2.39.15.1.1		not-accessible	This table is the voice extension to the call active table of DIAL-CONTROL-MIB. It contains voice encapsulation call leg information that is derived from the statistics of lower layer telephony interface.
hh3cVoiceCallActiveEntry	1.3.6.1.4.1.25506.2.39.15.1.1.1		not-accessible	The information regarding a single voice encapsulation call leg. The call leg entry is identified by using the same index objects that are used by call active table of DIAL-CONTROL-MIB to identify the call. An entry of this table is created when its associated call active entry in the DIAL-CONTROL-MIB is created and call active entry contains the call establishment to a voice over telephony network peer. The entry is deleted when its associated call active entry in the DIAL-CONTROL-MIB is deleted.
HH3 hh3cVoCallActiveConnectionId	1.3.6.1.4.1.25506.2.39.15.1.1.1.1	Hh3cGUid	read-only	The global call identifier for the gateway call.
G32 hh3cVoCallActiveTxDuration	1.3.6.1.4.1.25506.2.39.15.1.1.1.2	Gauge32	read-only	Duration of transmit path open from this peer to the voice gateway for the call. The units is milliseconds.
G32 hh3cVoCallActiveVoiceTxDuration	1.3.6.1.4.1.25506.2.39.15.1.1.1.3	Gauge32	read-only	Duration of voice transmitted from this peer to voice gateway for this call. The voice utilization rate can be obtained by dividing this by hh3cVoCallActiveTXDuration object. The units is milliseconds.
G32 hh3cVoCallActiveFaxTxDuration	1.3.6.1.4.1.25506.2.39.15.1.1.1.4	Gauge32	read-only	Duration of fax transmitted from this peer to voice gateway for this call. The fax utilization rate can be obtained by dividing this by hh3cVoCallActiveTXDuration object. The units is milliseconds.
HH3 hh3cVoCallActiveCoderType	1.3.6.1.4.1.25506.2.39.15.1.1.1.5	Hh3cCodecType	read-only	The negotiated coder type. It specifies the encode type to the PSTN leg of a call.
G32 hh3cVoCallActiveImgPageCount	1.3.6.1.4.1.25506.2.39.15.1.1.1.6	Gauge32	read-only	The number of fax related image pages are received or transmitted via the peer for the call. The units is pages.
