Description: Defines textual conventions for Session Initiation Protocol (SIP) management, including transport protocol types, entity roles, and method names.
IPNetwork Monitor uses several OIDs from this MIB in network discovery and polling the applicable devices. Start monitoring SIP-TC-MIB with a free 30-day trial of IPNetwork Monitor.
What Is SIP-TC-MIB?
SIP-TC-MIB is an IETF standards-track module (RFC 4780) that defines shared textual conventions for Session Initiation Protocol management, such as SIP transport protocol types, entity roles (proxy, registrar, user agent, etc.), and SIP method names. It belongs to the VoIP/telephony signaling category but is purely a definitional support module rather than a source of live data. It exposes no monitorable objects itself; instead it standardizes data types that other SIP MIBs (like SIP-COMMON-MIB or vendor SIP MIBs) reference to represent SIP-specific values consistently, so its relevance to monitoring is indirect, ensuring uniform interpretation of SIP roles and methods across implementations. As a textual-convention module it is explicitly designed to be imported by other SIP-related MIB modules, making that dependency central to its purpose. It is used wherever SNMP-managed SIP servers, proxies, or gateways are deployed, as a foundational building block rather than a standalone monitored entity. Engineers implementing or auditing this functionality typically reference the SIP-TC-MIB RFC/standard documentation for the authoritative specification.
IPNetwork Monitor allows you to monitor SNMP objects defined in SIP-TC-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
- vendor-neutral, standards-based MIB, not tied to a specific manufacturer; applies to any SNMP-managed SIP server, proxy, or gateway
Monitoring Examples
This is a TEXTUAL-CONVENTION-only module with no runtime data objects of its own; it defines types such as SIP method enumerations and entity-role values that other MIBs import to structure their tables. For example, a companion SIP call or server MIB might use a TC from this module to represent whether a monitored entity is acting as a SIP proxy, registrar, or user agent. There is no realistic direct monitoring scenario for this module in isolation since it contributes only shared data-type definitions.

RFC description
Session Initiation Protocol (SIP) textual conventions for SIP-related MIB modules.
Start monitoring vendor-neutral, standards-based MIB, any SNMP-managed SIP server/proxy/gateway (shared textual conventions) 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.
