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 SONUS-MGCP-SERVICES-MIB?

SONUS-MGCP-SERVICES-MIB is a proprietary Sonus Networks MIB for managing MGCP (Media Gateway Control Protocol) behavior on the vendor's media gateway, covering call-agent communication timers and endpoint/session tracking. It exposes configuration data (retransmission counts, command/response/critical/partial timeouts, message piggybacking) and session-state data (active MGCP session table). Its monitoring value lies in software/signaling health: confirming the gateway's timeout tuning is appropriate for the call agent's responsiveness and tracking active session counts to spot spikes or stuck sessions that fail to tear down. It directly implements parameters defined by the IETF MGCP protocol (RFC 3435). Typical deployment is on media gateways controlled by a softswitch/call agent via MGCP in VoIP/PSTN interconnect networks. Engineers can download the SONUS-MGCP-SERVICES-MIB file directly to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in SONUS-MGCP-SERVICES-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

  • Sonus Networks media gateway

Monitoring Examples

sonusMgcpGatewayCmdTimeout, sonusMgcpGatewayRspTimeout, and sonusMgcpGatewayMaxReXmit reveal the retransmission and timeout tuning affecting how the gateway tolerates call agent latency. sonusMgcpSessionTable/Entry (keyed by sonusMgcpSessionIndex) lets an operator poll the number and identity of active MGCP sessions, useful for spotting a session count spike or a session that fails to tear down, indicating a stuck endpoint.

What Can Be Monitored

  • active MGCP session count
  • command/response timeout settings
  • max retransmit count
  • gateway port configuration
  • message piggybacking setting
