The VaxVoIP WebPhone SDK uses WebRTC (Web Real-Time Communication) technology to deliver real-time audio, video, chat, and screen sharing directly in the browser. It enables developers to create secure, plugin-free VoIP webphones that reliably connect website visitors to your SIP servers or IP PBX systems without the need for any additional software or plugins.
Build a Webphone Using your own Design
The VaxVoIP WebPhone SDK lets you build a WebPhone with your own GUI design and branding.
Web-phone Based Solution Development
A WebPhone solution powered by the VaxVoIP WebPhone SDK delivers VoIP services directly through any browser. Built on WebRTC, it removes the need for extra software or plugins, making deployment simple and user-friendly. The solution is flexible, scalable, and works easily across both desktop and mobile environments.
This approach can be customized for various industries and use cases:
Call Centers
Agents can use a web browser-based dashboard to manage inbound and outbound calls, video meetings, and screen sharing. This allows them to help customers directly from the browser while reducing infrastructure costs and simplifying deployment.
Banking & Financial Services
Bank representatives can assist customers through a web-based dashboard, receiving calls to provide real-time account support, share loan details, and guide them through financial services, all without requiring extra software.
IP-Telephony Service Providers
Providers can deliver a ready-to-use browser phone for VoIP calls, enabling fast onboarding and service delivery without extra hardware or complex installations.
With a WebPhone solution, users can dial and receive audio calls, engage in video conferencing, exchange instant messages, and even share their screens, all within the browser. This creates a modern, plugin-free communication experience.
