Description: Monitors Cisco Unity voicemail and unified messaging system performance, mailbox counts, and call handler statistics.

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-UNITY-MIB?

CISCO-UNITY-MIB is a Cisco vendor MIB for monitoring Cisco Unity, a unified-communications voicemail and messaging server that provides voicemail, message-waiting indication, text-to-speech, and related unified messaging services. It exposes server-level identity and version information along with per-port status for the voice ports used to handle calls, message playback/recording, and integration signaling. This is directly a hardware/software status monitoring MIB for a UC application server: it lets an administrator confirm the Cisco Unity server's software version (ciscoUnityVersion), and check whether each individual voice port (ciscoUnityPortEntry) is enabled and correctly integrated with the phone system, which reveals capacity problems or port-level failures affecting voicemail service. Because Unity ports integrate tightly with a PBX/Call Manager, this MIB typically works alongside Cisco CallManager/Unified Communications Manager MIBs and telephony integration components (e.g., ties to MWI and AMIS/VPIM messaging standards mentioned in its acronym list). It is deployed on Cisco Unity servers within an enterprise unified-communications/voicemail environment. Engineers searching for cisco unity server monitoring reference this MIB to track Cisco Unity voicemail/messaging server health via SNMP.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-UNITY-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

  • Cisco Unity voicemail/unified messaging server

Monitoring Examples

An administrator would poll ciscoUnityTable/ciscoUnityEntry to confirm ciscoUnityName and ciscoUnityVersion match the expected deployed release, then check ciscoUnityPortTable/ciscoUnityPortEntry, keyed by ciscoUnityPortIndex/ciscoUnityPortNumber, to verify ciscoUnityPortEnabled is true and ciscoUnityPortIntegration/ciscoUnityPortExtension are correctly mapped. A port showing as disabled or with an unexpected extension mapping would indicate a voicemail port has dropped out of service, explaining calls failing to reach voicemail or MWI lamps not updating for affected mailboxes.

What Can Be Monitored

  • Unity server software version
  • voice port enabled/disabled state
  • voice port integration/extension mapping
  • port index/number identification
