Description: Provides common objects for Cisco voice dial control, shared across multiple voice transport MIBs.

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 CISCO-VOICE-COMMON-DIAL-CONTROL-MIB?

This Cisco MIB defines objects common to Cisco's voice dial-control management shared across multiple voice transport encapsulations—VoIP, Voice over ATM (VoATM), and Voice over Frame Relay (VoFR)—on Cisco voice gateways and routers. It exposes call-level data including currently active calls and historical call records, covering call setup parameters like voice activity detection (VAD), codec type/rate, in-band signaling, and caller ID/calling-name information. Its monitoring value lies in tracking the operational software status of the voice-call subsystem—active call counts, per-call codec/bandwidth usage, and completed-call history—rather than general chassis hardware health, letting operators detect stuck or excessive concurrent calls and codec negotiation issues. It is designed to be used alongside the technology-specific VoIP, VoATM, and VoFR dial-control MIBs which reference common objects registered under the CISCO-VOICE-COMMON-DIAL-CONTROL-MIB OID subtree, and depends on Cisco's broader dial-control MIB family. It is deployed on Cisco IOS voice gateways and routers providing PSTN/VoIP interworking in enterprise or carrier voice networks.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-VOICE-COMMON-DIAL-CONTROL-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.

Cisco VG410 Analog Voice Gateway (2024) — IOS-XE analog phone/fax gateway for Unified Communications Manager deployments

Monitoring Examples

An administrator would poll cvCommonDcCallActiveTable/cvCommonDcCallActiveEntry to see currently active calls, checking cvCommonDcCallActiveCoderTypeRate and cvCommonDcCallActiveCodecBytes to confirm codec negotiation and bandwidth consumption match expectations. Reviewing cvCommonDcCallActiveVADEnable and cvCommonDcCallActiveInBandSignaling helps diagnose voice quality complaints tied to VAD clipping or signaling mismatches. The cvCommonDcCallHistoryTable/cvCommonDcCallHistoryEntry rows, keyed by cvCommonDcCallHistoryConnectionId, let an operator audit recently completed calls for abnormal durations or repeated failures.

What Can Be Monitored

active call count
per-call codec type and rate
codec bandwidth usage
voice activity detection (VAD) status
in-band signaling status
call history records

STR cvCommonDcCallActiveCallingName	1.3.6.1.4.1.9.10.55.1.1.1.1.6	SnmpAdminString	read-only	The calling party name this call is connected to. If the name is not available, then it will have a length of zero.

It specifies the transmit rate of voice/fax compression to its associated call leg for the call. This rate is different from the configuration rate because of rate negotiation during the call.
CVC cvCommonDcCallActiveConnectionId	1.3.6.1.4.1.9.10.55.1.1.1.1.1	CvcGUid	read-only	The global call identifier for the network call.

The call leg entry is identified by using the same index objects that are used by Call Active table of IETF Dial Control MIB to identify the call. An entry of this table is created when its associated call active entry in the IETF Dial Control MIB is created and the call active entry contains information for the call establishment to a network dialpeer.
