With nearly a decade of experience in web and mobile app development, I can confidently assert that I have the technical know-how you need to build a production-ready SS7 <-> SMPP Gateway Using JSS7. Throughout my career, I have consistently produced high-quality work for my clients and I'm confident I can extend the same level of proficiency to your project. Moreover, my expertise in Android is highly relevant to the Linux-based JSS7, giving me an edge in designing a robust and efficient gateway. I understand the core purpose of this application is message routing and reliability - and therefore guarantee these will be at the forefront of my design. Using my skills in Java and PHP5 - both key elements in your project description - I'll create a well-structured code comprising a clean SS7 interface layer (MAP/TCAP over M3UA/SCTP), a modular protocol conversion core, and a reliable SMPP 3.4/5.0 transmitter/receiver component. Lastly, working with open-source dependencies is inherent in my approach to software development. From your straightforward config file to the end-to-end messaging flow without any loss or corruption, I will deliver not only the full source code but also detailed documentation on its build, configuration, basic troubleshooting alongside relevant test scripts/proofs like pcap files to demonstrate signaling integrity. Let's turn your ideas into reality!

I can develop a production-ready SS7 ↔ SMPP gateway built entirely around the open-source JSS7 stack, focused exclusively on reliable real-time message routing. The solution will be modular, lightweight, Linux-native, and free from unnecessary components such as billing engines, dashboards, or commercial dependencies. The gateway will support inbound SS7 signaling over SIGTRAN and route messages cleanly toward SMPP clients/providers while preserving message integrity, ordering, and delivery consistency. The architecture will be designed for operational simplicity, maintainability, and high-throughput telecom workloads. Proposed Architecture 1. SS7 Signaling Layer Responsible for handling telecom signaling transport and MAP/TCAP message processing. Components SCTP transport M3UA adaptation layer SCCP routing TCAP session handling MAP parsing/encoding Technology Open-source JSS7 stack Java 17+ Linux SCTP support

Hi, I’ve built SS7/SMPP gateways and worked with JSS7, M3UA, and SMPP 3.4/5.0 in production environments. I understand you need a lean, production-ready gateway that routes signaling from SS7 to SMPP with zero extra features. Here’s how I’ll deliver: **1. Modular Architecture** - SS7 Layer: MAP/TCAP over M3UA/SCTP using Restcomm JSS7 stack - Conversion Core: Clean protocol translation logic

We can do this project easy because more experience on your telling on deploy the service on a fresh server, • plug an STP or SIGTRAN link into it, • bind an SS7 & SMPP client, • see messages flow end-to-end without loss, duplication, or corruption, • and adjust routing rules from a straightforward config file.

Hi there, Instead of a generic approach, I will deliver a production-grade, low-latency SS7-to-SMPP gateway built strictly around the open-source JSS7 stack on Linux, optimized for zero packet loss. This gateway addresses critical real-time parameters to guarantee seamless telco interoperability: Core Architecture: 1. SIGTRAN Ingress: Maps MAP/TCAP over M3UA/SCTP in ASP mode. Uses Java 17+ and the Z Garbage Collector (ZGC) to keep runtime pauses below 1ms, preventing SCTP heartbeat dropouts. 2. Stateful Engine: Integrates a thread-safe concurrent map linking incoming TCAP Transaction IDs directly to outbound asynchronous SMPP Sequence Numbers, ensuring correct TCAP End handshakes. 3. Payload & UDH Parsing: Decodes MAP octets via ASN.1 rules, mapping binary User Data Headers (UDH) directly to SMPP SAR parameters to handle multi-part concatenated SMS seamlessly. 4. SMPP Egress (ch-smpp/JSMPP): Implements an asynchronous TCP Transceiver (v3.4/5.0) with sliding-window backpressure handling to protect network buffers. Managed via a declarative YAML file. Deliverables include full Maven source code, a step-by-step README, and a validated Wireshark PCAP trace proving signaling integrity. Let's connect to review your configuration schema! Best regards, Hassan

Hi I'm Unathi I’ll deliver a production-ready, Linux-based gateway built entirely on the open-source JSS7 stack that routes SS7 MAP/TCAP signaling over M3UA/SCTP into SMPP 3.4/5.0 with zero unnecessary features. Using Java for the core and C where native performance is needed, I’ll structure the code modularly with three clean layers: an SS7 interface layer handling TCAP/MAP, a protocol conversion core for reliable message mapping, and an SMPP transmitter/receiver component for upstream delivery. The solution will compile with open-source dependencies only, run on a fresh Linux server, and use a straightforward config file for routing rules so you can plug in an STP/SIGTRAN link, bind SS7 and SMPP clients, and see messages flow end-to-end without loss, duplication, or corruption. You’ll receive the full source code, a complete README covering build, config, and basic troubleshooting, plus a test script/pcap to prove signaling integrity and real-time performance under load.
