VoIP/WebRTC security has needed a DVWA equivalent for a long time. We built DVRTC: full dockerized VoIP stack, intentionally vulnerable, 7 guided exercises.

Live instance at pbx1.dvrtc.net — try it now.

Web application security has DVWA and WebGoat. VoIP and WebRTC security hasn't had anything like it ... until now.

We built DVRTC (Damn Vulnerable Real-Time Communications): a hands-on lab for learning VoIP/WebRTC attack techniques. Full dockerized stack with Kamailio, Asterisk, rtpengine, and coturn — each configured to exhibit specific vulnerable behaviors.

7 exercises covering SIP extension enumeration, RTP bleed, SIP digest leaks, credential cracking (online and offline), TURN relay abuse, and traffic analysis. There's a live instance at pbx1.dvrtc.net you can test against right now.
