What Is US-SRX-SIP-MIB?

US-SRX-SIP-MIB is a vendor-specific MIB whose MODULE-IDENTITY organization is Siemens Network Convergence LLC (part of Siemens Enterprise Communications' HiQ 8000 / SURPASS RTP softswitch platform), registered under the hiq8000Admin branch — despite the vendor field on this entry naming Juniper, the source module's copyright, organization, and IMPORTS (SURPASS-RTP-MIB, HIQ-ADMIN-MIB) confirm it is a Siemens SIP Signal Manager MIB unrelated to Juniper's SRX security appliances, a naming coincidence worth flagging. It defines usSrxSipConfigStatisticsData with per-message SIP performance counters (usSrxSipPerfInviteMsgsSentByClient, usSrxSipPerf100TryingMsgsRcvdByClient, usSrxSipPerf180RingingMsgsRcvdByClient, and similar counters for other SIP response codes) plus usSrxSipReasonMgmt for SIP reason-header management. This message-level counter granularity is useful for monitoring SIP call-signaling health on the softswitch — confirming that INVITE requests are being answered with expected provisional and final responses rather than timing out. It depends on the vendor's FSC-RTP-MIB, SURPASS-RTP-MIB, SURPASS-RTP-ADMIN-MIB, and HIQ-ADMIN-MIB for shared types and its OID root, and is deployed on Siemens HiQ 8000/SURPASS RTP SIP softswitch platforms; administrators can download the US-SRX-SIP-MIB file to load it into their MIB browser.

IPNetwork Monitor allows you to monitor SNMP objects defined in US-SRX-SIP-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

  • Siemens HiQ 8000 / SURPASS RTP SIP softswitch platform

Monitoring Examples

An operator polls usSrxSipPerfInviteMsgsSentByClient alongside usSrxSipPerf180RingingMsgsRcvdByClient over a polling interval to compute a ringing-response ratio for outbound SIP calls; a sustained drop in that ratio while INVITE volume stays constant would indicate downstream SIP endpoints are failing to respond, pointing to a signaling or trunk-side problem.

What Can Be Monitored

  • INVITE messages sent by SIP client
  • provisional response counters (100 Trying, 180 Ringing)
  • SIP reason-header management objects
  • per-message-type SIP performance statistics

How to Use in IPNetwork Monitor

Example using usSrxSipPerfInviteMsgsSentByClient OID:

Select a Siemens HiQ 8000 / SURPASS RTP SIP softswitch platform (per-message SIP response-code counter status) 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 usSrxSipPerfInviteMsgsSentByClient into the Find box to locate it in the OID tree, then select it and click OK. This value identifies the count of Invite messages sent from Client. 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 an Integer32-type OID, Value bounds is the most useful condition here — trigger an alert if the count changes from its expected baseline, since that would indicate the underlying set of items changed unexpectedly. Click Finish to create the monitor; you can adjust any parameter later.
