oSTP – SS7 M3UA Signaling Transfer Point

oSTP (aka OSMOCOM Signaling Transfer Point) is yREMORA’s dedicated M3UA STP (Signaling Transfer Point) solution, engineered for modern telecommunications networks requiring MTP3 User Adaptation Layer connectivity. Built on the robust open-source OSMOCOM STP framework with integrated SCCP (Signaling Connection Control Part) stack (formerly osmo-sccp), oSTP delivers enterprise-grade SS7 message routing and addressing over IP with the flexibility of contemporary deployment architectures.

Key Capabilities

Flexible Deployment Models

Deploy oSTP in containerized environments (Docker), virtualized infrastructure (VMware, KVM, OpenStack), or directly on bare-metal servers. Choose the architecture that fits your operational requirements.

M3UA Protocol Support

Seamlessly connects to any ASP (Application Server Process) or SGW (Signaling Gateway) via M3UA (MTP3 User Adaptation Layer), enabling SS7 signaling over IP networks with full SCTP association management and failover capabilities.

Integrated SCCP Stack

Built-in SCCP (Signaling Connection Control Part) layer provides complete SS7 routing and addressing capabilities, including Global Title Translation (GTT), connection-oriented and connectionless services, and subsystem management—all within a unified platform.

Advanced Multi-Homing Architecture

Supports SCTP (Stream Control Transmission Protocol) multi-homing with 2-to-2 IP address configurations for enhanced redundancy and failover capabilities. Single-home deployments (1-to-1 IP) also supported for simplified network topologies.

Intelligent Regex-Based Routing

Powerful regular expression pattern matching enables sophisticated routing logic with granular control over SS7 traffic flows:

Global Titles (GT): E.164, E.212, E.214 addressing schemes
Point Codes: ANSI and ITU format support
Subsystem Numbers (SSN): Application-layer routing
Service Indicators (SI): Protocol-based filtering
Custom SCCP/TCAP Parameters: Advanced routing criteria

Dynamic Routing Tables

Real-time route updates without service interruption via API provisioning. Modify routing policies, add new routes, or adjust traffic patterns on-the-fly without impacting active signaling sessions.

RESTful API Management

Comprehensive API for configuration, provisioning, monitoring, and management—enabling automation, integration with OSS/BSS systems, and programmatic control of routing policies.

Open-Source Foundation

Leveraging the proven OSMOCOM STP framework (github.com/osmocom/libosmo-sccp) ensures transparency, community-driven innovation, and freedom from vendor lock-in while maintaining enterprise-grade reliability.

Ideal For

Perfect for mobile operators, MVNOs, interconnect providers, and enterprises requiring reliable M3UA-based SS7 routing infrastructure with integrated SCCP capabilities and modern deployment flexibility.
