Description: Monitors Cisco Survivable Remote Site Telephony (SRST) fallback mode activation and registered phone counts.

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-SRST-MIB?

CISCO-SRST-MIB manages Cisco Survivable Remote Site Telephony (SRST), an IOS feature that provides Cisco IP phones at a branch site with fallback call-processing support if connectivity to a central Cisco Unified CallManager is lost. It belongs to the IP telephony/voice-survivability technology area and exposes configuration and status data including whether SRST is enabled, its version, the CallManager IP address/port it serves as fallback for, and capacity limits for conferences, registered ephones, and directory numbers. Its monitoring emphasis is on software feature/service status: whether SRST fallback mode is currently active (a direct indicator that the primary CallManager link has failed), how many phones are registered against configured maximums, and thresholds like csrstSipPhoneUnRegThreshold that flag when too many SIP phones have failed to register. The module explicitly notes its close relationship to CISCO-CCME-MIB, which manages the related CallManager Express feature, since both share IOS telephony infrastructure. It is typically deployed on Cisco ISR/branch routers configured as SRST fallback gateways for remote-office IP phone deployments. Engineers researching what cisco srst is on a branch router use this MIB to monitor SRST fallback status when the primary Cisco Unified Communications Manager becomes unreachable.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCO-SRST-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 ISR/branch router (SRST gateway)

Monitoring Examples

An operator would poll csrstEnabled and csrstVersion to confirm SRST fallback capability is active and running the expected feature version on a branch router, then check csrstMaxEphones and csrstMaxDN against the actual number of currently registered phones to see if the site is approaching its supported capacity. If csrstSipPhoneUnRegThreshold is being exceeded, that flags that an unusual number of SIP phones have failed to register with SRST, which combined with csrstIPAddress/csrstPortNumber pointing at an unreachable central CallManager, would confirm the branch has failed over and phones are struggling to re-home locally.

What Can Be Monitored

SRST enabled/fallback status
registered ephone count vs. maximum
directory number count vs. maximum
SIP phone unregistered threshold
call forward busy/no-answer configuration

How to Use in IPNetwork Monitor

Example using csrstSipCallLegs OID:

Select a Cisco ISR/branch router (SRST gateway) 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 csrstSipCallLegs into the Find box to locate it in the OID tree, then select it and click OK. It reports the total number of SIP call legs routed through the SRST router since going active. 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.

OIDs

OID symbolic	OID numeric	Type	Access	Description
ciscoSrstMIB	1.3.6.1.4.1.9.9.441			This MIB allows management of Cisco Survivable Remote Site Telephony (SRST) feature in Cisco IOS. SRST is an optional software feature that provides Cisco CallManager with fallback support for Cisco IP phones attached to a Cisco router on a local network. The CISCO-CCME-MIB provides management of Cisco CallManager Express (CCME) feature in Cisco IOS. CCME is an optional software feature that enables Cisco routers to deliver IP telephony services for small office environment. Ephone, ephoneDN, button association tables are common to both CCME and SRST MIBs and are defined in CISCO-CCME-MIB. Ephone specific notifications which are common to CCME and SRST are also defined in CISCO-CCME-MIB.
