Description: Manages multimedia mail dial control including fax and voice messaging sessions on Cisco gateway platforms.

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-MMAIL-DIAL-CONTROL-MIB?

CISCO-MMAIL-DIAL-CONTROL-MIB is a Cisco vendor extension MIB that enhances the IETF Dial Control MIB (RFC 2128) to manage multimedia mail dial peers, fax and voice messaging sessions bridging a circuit-switched telephony network and an IP mail server, on Cisco voice gateway platforms. It exposes configuration data for IP dial peers (session protocol, session target, image encoding type/resolution for fax) as well as active call session data tracking live connections. Its monitoring value is around software/service status of ongoing calls: cmmIpCallActiveTable lets an operator see currently active multimedia mail calls (via cmmIpCallActiveConnectionId and cmmIpCallActiveRemoteIPAddress), while notification-enable objects like cmmIpPeerCfgMsgDispoNotification and cmmIpPeerCfgDeliStatNotification indicate whether message-disposition and delivery-status traps are enabled for a peer. As stated in its module description, it explicitly builds on and extends IETF RFC 2128 (Dial Control MIB), and it is typically deployed on Cisco voice/fax gateway routers providing unified-messaging or fax-over-IP dial-peer services. Engineers can download the CISCO-MMAIL-DIAL-CONTROL-MIB file directly to load it into their MIB browser.

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

Supported Devices

  • Cisco voice/fax gateway router (unified messaging platform)

Monitoring Examples

An admin would poll cmmIpCallActiveTable to see the current count and detail of active fax/voice-mail calls, using cmmIpCallActiveConnectionId to correlate a specific call and cmmIpCallActiveRemoteIPAddress to identify the remote mail server or gateway endpoint. Checking cmmIpPeerCfgTable entries (cmmIpPeerCfgSessionProtocol, cmmIpPeerCfgSessionTarget, cmmIpPeerCfgImgEncodingType/Resolution) confirms a dial peer is configured with the expected fax encoding and resolution before troubleshooting failed fax deliveries. If cmmIpPeerCfgDeliStatNotification is enabled, the gateway would emit a trap on delivery failure, letting operators react to fax/voice-mail delivery problems in near real time.

What Can Be Monitored

  • active fax/voice-mail call sessions
  • dial peer session protocol/target
  • fax image encoding type and resolution
  • message disposition/delivery notification status
