Core Capabilities

Everything You Need for Voice Operations

RustPBX unifies SIP trunking, call routing, real-time billing, CDR analytics, and observability in a single open-source softswitch — for wholesale carriers, call centers, and enterprise PBX.

System Stability

Security & System Stability

Carrier-grade reliability built on Rust's async runtime, with layered protection against fraud and abuse.

High-concurrency architecture with asynchronous processing ensures carrier-grade reliability and 99.9%+ uptime
Intelligent security protection: IP ACLs, scanner User-Agent blacklists, and firewall defenses against DDoS attacks and unauthorized access
Real-time monitoring and automated alerts for system health, active calls, and resource utilization

FAQ

Frequently Asked Questions

Common questions about RustPBX, wholesale switching, and running a call center on Miuda.ai.

Is RustPBX free and open source?

Yes. The RustPBX core is open source under the MIT license, including the SIP proxy, media engine, call records, and web console. Miuda.ai additionally offers commercial editions with license activation for advanced addons such as clustering and wholesale billing.

Which protocols and codecs does RustPBX support?

RustPBX speaks SIP (UDP/TCP/TLS), SIP over WebSocket for WebRTC, and SRTP including DTLS-SRTP and SDES-SRTP. Audio codecs cover G.711 a/µ, G.729, G.722, Opus, and iLBC, selectable per trunk or extension, with transcoding in the media bridge.

Can I run a wholesale voice business on it?

Yes. The wholesale addon adds tenant management, rate decks, routing profiles with least-cost routing, circuit breakers with sliding-window ASR/ACD monitoring, real-time billing, and per-tenant CDR — a complete class 4 softswitch and BSS stack.

What call center features are included?

Skill-based routing with ACD queues, agent state management with wrap-up time, overflow strategies, real-time supervisor monitoring with listen/whisper/barge-in, screen-pop with Call-Info/User-to-User headers, and post-call CSAT surveys.

Does it integrate with AI voice services?

Yes. RustPBX integrates ASR/TTS drivers, per-call transcription plans, a realtime AI-voice bridge for LLM agents, and an IVR engine with dynamic prompts — so you can build AI-powered voice agents that hand off to human agents in the same platform.

How do I deploy RustPBX?

Deploy via Docker or as a single static binary on Linux. A built-in web console handles extensions, trunks, routing, and diagnostics; SQLite works out of the box, with MySQL/PostgreSQL recommended for clusters. See the basic setup guide for a first call in minutes.
