    Our Services

    Connecting the Web to Telephony with SIP.js

    At Xinzex, we build high-performance, browser-based VoIP applications using SIP.js, a lightweight JavaScript library that allows real-time audio, video, and messaging over WebRTC and SIP. Our development services bridge the gap between modern browsers and backend communication infrastructure.

    Custom Browser Calling Solutions

    We develop softphones and embedded dialers directly in your web apps, making it easy for users to initiate or receive calls with no downloads or plugins required.

    SIP.js API Integration

    Connect SIP.js with existing SIP servers (like FreeSWITCH, Asterisk, Kamailio) using secure WebSockets and build real-time dashboards, CRMs, or contact centers.

    WebRTC Media Handling

    Deliver high-quality voice and video via WebRTC with ICE, STUN, and TURN servers—optimized for stability across NAT, firewalls, and mobile networks.

    Custom User Interfaces

    From sleek single-line softphones to complex call control dashboards, we build frontends using SIP.js and modern frameworks like React and Vue.js.

    Secure & Scalable Architecture

    We use secure signaling (WSS/TLS), DTLS encryption, and token-based authentication to ensure your SIP.js applications are scalable and protected.

    Call Control Features

    Implement call transfer, hold, mute, conference, DTMF, and more all accessible via the SIP.js client and controlled via backend logic.

    Performance Monitoring & Analytics

    Track call performance, session activity, and error logs using built-in metrics and integration with third-party monitoring tools.

    Progressive Web App (PWA) Ready

    We can develop SIP.js-based softphones as PWAs that work seamlessly on mobile and desktop with push notifications and offline capabilities.
