What Is HPN-ICF-VOICE-CALL-ACTIVE-MIB?

HPN-ICF-VOICE-CALL-ACTIVE-MIB is a vendor-specific MIB from HP (H3C/Comware-based ICF architecture, "hpnicf" prefix) covering real-time monitoring of currently active voice calls on HP/H3C voice gateway devices. It exposes an active call table with connection identifier, transmit/voice/fax duration, codec ("coder type"), and fax image page count, plus a parallel VoIP-specific active call table for calls carried over IP. Its monitoring focus is on live call/service status rather than hardware: seeing how many voice calls are active, which codec each uses, how long each call/fax has run, and detecting calls stuck at unexpectedly long duration or using an unexpected codec, indicating signaling or media-path problems. It is a vendor-specific extension for voice gateway call monitoring, conceptually related to but not directly dependent on IETF voice/media MIBs. It is deployed on HP/H3C voice gateway or media gateway equipment in enterprise or carrier VoIP/PSTN gateway deployments needing real-time call-state visibility, which the HPN-ICF-VOICE-CALL-ACTIVE-MIB MIB is specifically designed to provide.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-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

HP/H3C voice gateway
HP/Comware media gateway

Monitoring Examples

An operator would poll hpnicfVoiceCallActiveTable/hpnicfVoiceCallActiveEntry to read hpnicfVoCallActiveCoderType and hpnicfVoCallActiveTxDuration for each active call, and check the parallel hpnicfVoiceVoIPCallActiveTable for VoIP-specific calls keyed by hpnicfVoVoIPCallActiveConnectionId. A call with an unusually long hpnicfVoCallActiveFaxTxDuration or an unexpected hpnicfVoCallActiveCoderType would indicate a stuck fax transmission or codec negotiation issue on that gateway.

What Can Be Monitored

number and identity of active voice calls
call/fax transmit duration
codec/coder type in use
fax page count
active VoIP call connections

OID symbolic	OID numeric	Type	Access	Description
hpnicfVoCallActive	1.3.6.1.4.1.11.2.14.11.15.2.39.15			This MIB file is to provide the definition of voice call active record information.

hpnicfVoiceCallActiveTable	1.3.6.1.4.1.11.2.14.11.15.2.39.15.1.1		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.
hpnicfVoiceCallActiveEntry	1.3.6.1.4.1.11.2.14.11.15.2.39.15.1.1.1		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.
