SMPP Setup Expert – India SMS Routing

@espsofttech

Hi there, We have delivered messaging and communication platforms with SMS integrations and understand SMPP flows, and got you already have your platform, VPS, and infrastructure ready—so the main focus is setting up and stabilizing the SMPP layer. Once you share the SMPP credentials and current setup, we can jump in and configure bind (TX/RX/TRX), make sure message submission and DLR flow is working correctly, and connect it cleanly with your existing Node.js setup. We will also take care of connection stability (enquire_link, reconnect), check encoding issues, fix any delivery or mapping gaps, and tune things so it works reliably on Indian routes. We would request to connect once so we can quickly review your current flow and get this running smoothly. Thanks, Rahul A.

With utmost respect, I must say that my name is Mashnun Hossain, and I am genuinely the most fitting freelancer for your SMPP Setup Expert – India SMS Routing project. Armed with 10+ years of professional experience as a Full Stack Developer, my expertise extends to Linux, MySQL and PHP - the trifecta crucial for ensuring smooth implementation and stability in any given project. Having previously worked with Indian SMS routes/providers, I have intimate knowledge of the idiosyncrasies involved in establishing and stabilizing SMPP connectivity for SMS delivery across India. Furthermore, during my years of practice, I’ve fine-tuned my ability to debug low-level protocol issues (PDU parsing, session drops, etc.) which will be of critical value in guaranteeing reliable message submission (submit_sm) and delivery receipt handling from your platform. Moreover, my familiarity with throughput tuning and throttling, combined with a deep understanding of error codes means faster troubleshooting for any connectivity or encoding issues that may arise. Lastly, our team firmly understands the importance of effective communication, clean implementation, and reliable delivery when it comes to propelling a project forward. We believe in results-driven work that is high-quality, scalable, maintained at cost-effective pricing while remaining client-focused. In conclusion, let's discuss your project further so we can set up better SMPP connectivity for robust SMS delivery together!

I can configure the TRX sessions, handle the enquire_link drops within your BullMQ workers, and map the Indian route DLR statuses straight to Postgres. Which Node.js SMPP library are you currently using to bind with the provider?

@loxtic

Hello, how are you doing? I have configured SMPP connections for Indian routes before, handling TX/RX/TRX binds, submit_sm, DLR mapping, and session management in Node.js environments with Redis queues. I’ve worked with providers, encoded GSM payloads, and tuned throughput to keep delivery stable on busy routes. I can plug into your existing stack (Node.js, BullMQ, PostgreSQL) and stabilize SMPP connectivity end-to-end. Let me know further if interested.

Establishing and stabilizing SMPP connectivity in India demands not only a deep understanding of the SMPP protocol but also the nuances of local SMS provider environments and encoding requirements. Given your robust tech stack, particularly with Node.js, my focus will be on optimizing the SMPP bind operations and ensuring efficient message submission and delivery receipt handling. The immediate actions include configuring the connection, debugging low-level protocol interactions, and implementing best practices tailored for high deliverability in Indian routes. Expect an initial deliverable in 10 days. Want to see a quick deliverable preview before committing?

@ViktorUmanskyi

As a seasoned backend Python developer, I see a perfect synergy between your project requirements and my skillset. Although primarily Django-oriented, I believe my ability to effectively understand and navigate through FastAPI patterns will be pivotal here. Over the past 3 years, I have successfully delivered multiple large-scale projects dealing with SMS capabilities, database management (MySQL, PostgreSQL), as well as asyncio capabilities, all of which are highly relevant to your SMPP setup requirement. In addition, I am no stranger to working with third-party APIs and integrating them seamlessly into existing systems. My experience implementing secure authentication token flows like JWT/OAuth aligns directly with the work needed to ensure proper message submission and delivery receipt handling that you require. Notably, I bring more than just technical skills to this project. With every task I undertake, I prioritize reliability and stability, two crucial elements for SMTP connectivity. This means doing all it takes to debug any potential hiccup along the way; from low level protocol issues to debug low-level protocol issues (PDU Parsing) or session drops in order to optimize connection handling and mitigate any coding related challenges that may arise. Ultimately,

I’ll establish SMPP connection using provided credentials. 3. Validate bind operations (TX/RX/TRX). 4. Optimize connection handling and debug any issues. 5. Assist with DLR status mapping and GSM encoding. I have extensive experience with SMPP, Node.js, and Indian SMS routes. Let’s talk as soon as possible and get it done. Best Regards, Mihajlo

@afink

Hello I can help you with this. I have written SMPP servers myself and participated on developing Kannel.org. The bid is a placeholder as its still unclear on how much work it would be but I charge 100$ per hour.
