Description: Manages SIP user agent configuration, dial peers, and protocol statistics on Cisco voice gateways and CUCM.

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-SIP-UA-MIB?

CISCO-SIP-UA-MIB is a Cisco vendor-specific MIB that manages and monitors the SIP User Agent (UA) functionality on Cisco voice gateways and Cisco Unified Communications Manager, covering both per-dial-peer SIP configuration and protocol-level statistics. Its cSipCfgPeerTable (indexed by cSipCfgPeerIndex) exposes per-dial-peer SIP settings such as cSipCfgPeerOutSessionTransport (UDP/TCP), cSipCfgPeerReliable1xxRspHdr, and cSipCfgPeerUrlType, layered on top of system-wide defaults, while cSipCfgEarlyMediaTable and cSipCfgBindSourceAddrTable carry related transport and early-media configuration. Protocol health is tracked through statistics tables like cSipStatsSuccessOkTable, which records inbound and outbound 200 OK response counts per SIP method (cSipStatsSuccessOkInbounds/Outbounds), alongside broader success/failure counters for transactions across the UA. It depends on CISCO-VOICE-DIAL-CONTROL-MIB for identifying which dial peers use SIP, and it is deployed on Cisco IOS voice gateways and CUCM systems handling SIP call signaling, where a network engineer monitoring SIP call processing would query this MIB — the reference MIB for Cisco sip ua — to check response and dial-peer statistics.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SIP-UA-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 IOS voice gateways
  • Cisco Unified Communications Manager (CUCM) / Call Manager Express

Monitoring Examples

An operator polls cSipStatsSuccessOkTable to compare cSipStatsSuccessOkInbounds and cSipStatsSuccessOkOutbounds for the INVITE method, and checks cSipCfgPeerTable for a given dial peer's cSipCfgPeerOutSessionTransport setting; a sharp drop in outbound 200 OK counts alongside failure-cause counters rising would indicate a SIP signaling problem on that dial peer.

What Can Be Monitored

  • per-dial-peer SIP configuration table
  • SIP transport/session settings
  • 200 OK success response counters by method
  • SIP transaction success/failure statistics
  • early media and source address binding configuration

How to Use in IPNetwork Monitor

Example using cSipStatsInfoTryingIns OID:

Select a Cisco IOS voice gateway or Unified Communications Manager as the target host to create a monitor — the SNMP service should be up and running on it. Click New Monitor, then check SNMP Custom on the Favorites tab, click Next, and confirm the host. On the next page, click Select... to open the built-in SNMP MIB Browser and type cSipStatsInfoTryingIns into the Find box to locate it in the OID tree, then select it and click OK. This object reflects the total number of Trying (100) responses received by the user agent since system startup. On the monitor's Main parameters page you can set the target's SNMP port (default 161), credentials, polling interval, and other settings — see the SNMP Monitor help for details. On the State conditions and Alerting tabs, configure when the monitor should change state and trigger an alert; since this is a Counter32-type OID, Value bounds is the most useful condition here — trigger an alert if the counter increases sharply between polls relative to its normal baseline, since an unexpected spike often reflects a real change in traffic or activity. Click Finish to create the monitor; you can adjust any parameter later.
