VoIPBIN is a CPaaS (Communications Platform as a Service) designed to simplify and empower voice and messaging solutions for developers, startups, and enterprises alike.

"CPaaS for all."

• 🌍 Project Site — Landing page for VoIPbin
• 🔧 Admin Console — Admin console for voipbin(Demo account is ready)
• 📞 Agent — Simple web application demo for agent
• 🎥 Meeting — Simple web application demo for video/voice conference meeting

Detailed documentation is available here:

• 📘 API Documentation — Explore and test VoIPbin APIs

• Programmable Voice Flows: Design advanced call logic using declarative JSON-based Flows with branching, loops, forking, and post-call hooks
• SMS & Messaging Flows: Handle incoming and outgoing messages using the same flow engine. Enables surveys, notifications, and chatbot replies.
• Extension Management: Register SIP/WebRTC clients, assign extensions, and route calls to the right agent, queue, or flow.
• Call Queues & Agent Management: Create call queues with priority rules, agent login/logout, ring strategies, and call wait handling.
• Outbound Campaigns: Launch bulk voice or SMS campaigns via API or UI. Campaigns can use flows to automate actions per call/message.
• Multitenancy & Customer Isolation: Full tenant separation with isolated configurations, flows, agents, and access control. Designed for SaaS CPaaS scenarios.
• Conferencing & Moderation Tools: Host secure, real-time audio conferences with recording, breakout rooms, and moderator roles.
• Chat & Web Messaging: Support real-time messaging between customers and agents. Designed for seamless web or mobile integration.
• AI-Powered Voice: Integrate chatbot flows that understand user input, trigger smart actions, and provide fallback TTS messaging.
• Real-time Transcription: Transcribe speech on the fly or after the call, optionally summarized via AI with customizable flow triggers.
• Call Recording: Record conversations, generate transcripts, and summarize content using post-call flow execution.
• Webhook & HTTP Integration: Trigger webhooks mid-call or post-call, and dynamically adjust flows based on real-time external responses.
• Flexible Flow Execution: Use fork, next_action_id, and conditionals to model real-world conversation logic. Async execution supported.
• Codec & Media Control: SRTP, OPUS, PCMU, PCMA support via RTPEngine. Transcoding minimized for low-latency audio.
• Secure Registration & Authentication: Digest auth for SIP/WebRTC, token-based auth for API, tenant-based access segregation.
• ... And more and more!

VoIPBIN is composed of microservices designed to work together or independently:

• monorepo(https://github.com/voipbin/monorepo): Monorepository for the backend services.
• voipbin-go(https://github.com/voipbin/voipbin-go): voipbin SDK for golang.

⚠️ VoIPbin is not a plug-and-play application.

It's a platform composed of multiple microservices, SIP/media infrastructure (e.g., Asterisk, RTPEngine), Kubernetes-based deployments, and cloud integrations (e.g., Twilio, OpenAI). You don't just "run it" — you assemble and deploy it based on your architecture.

That said, here's how to begin:

VoIPbin is composed of multiple services that run independently and communicate over HTTP, gRPC, SIP, and WebRTC. You’ll need:

• A Kubernetes environment (we recommend GCP GKE)
• Compute engine with static public IP Address
• A public domain with TLS (e.g., via Cloudflare)
• A media path (RTPEngine or equivalent)
• Optionally, Asterisk instances for call bridging, conferencing, and SIP registration

We recommend reading the platform architecture guide (coming soon) before setup.
