I have just completed a similar project. I developed a Linux-based telephony service that seamlessly integrated WhatsApp messaging with SIP trunk inbound and outbound calls, featuring real-time call tracking and robust API endpoints. You won’t find a specialist better aligned with what you’re looking for. I understand the importance of reliability and scalability in managing unified communications through a single platform. I specialize in transforming complex business requirements into high-converting, user-centric digital assets. I’d love to chat about your project! The worst that can happen is you walk away with a free consultation. Regards, Bjork Bronkhorst
