High-Availability VoIP & Media Orchestration
A carrier-grade SIP gateway designed for handling large-scale VoIP traffic. It integrates Drachtio for SIP signaling and RTPEngine for media proxying, providing a robust bridge between disparate telecom networks.
To build a programmable, scalable voice infrastructure that can handle thousands of concurrent calls with sub-millisecond signaling latency.
Developed a custom NestJS gateway using the Drachtio framework. Implemented advanced media handling via RTPEngine, including transcoding and secure RTP (SRTP) termination.
Successfully deployed as a core component for a distributed PBX system, supporting high-fidelity voice calls and complex call routing logic.
