What You Can Build

The Platform Behind Anything You Imagine

Vinix isn't just a phone system — it's a programmable communications platform. Here's what developers are building on it.

White-Label UCaaS

Build and resell your own branded business phone service. Custom portals, your logo, your pricing — powered entirely by Vinix infrastructure.

Custom Contact Center

Embed intelligent call routing, real-time monitoring, agent dashboards, and CRM screen-pops into your own contact center application.

CRM & Helpdesk Integration

Connect Salesforce, HubSpot, Zendesk, or any CRM. Auto-log calls, pop caller records, trigger workflows on call events.

Global Voice Applications

Build IVR trees, appointment reminders, 2FA voice calls, and interactive voice menus in 200+ countries using the same API.

AI-Powered Voice Bots

Integrate your LLM with live calls via WebSockets. Stream audio, inject TTS responses, and hand off to a human agent seamlessly.

Click-to-Call & WebRTC

Embed a softphone or click-to-call widget directly in your web app. SIP over WebRTC — no plugin, no download, just a JS SDK.
