Mr.SIP Pro Documentation

A complete guide to installing, licensing, and using Mr.SIP Pro for VoIP security testing.

1. Introduction

Mr.SIP Pro is a professional-grade VoIP security suite built to conduct deep security assessments across SIP and RTP infrastructures. With a modular interface and over 18 attack and analysis modules, Mr.SIP Pro enables users to uncover weaknesses, simulate abuse scenarios, and validate the resilience of SIP-based environments.

Capabilities include multi-threaded scanning, dynamic SIP message generation, IP spoofing simulation, and attack chaining. Its user interface streamlines complex assessments into repeatable and scalable workflows — designed for both security consultants and enterprise security teams.

2. Installation & Licensing

  • Supports Linux (Ubuntu 20.04+) and Windows 10+ environments.
  • Installers and binaries are delivered via the user dashboard after purchase.
  • Initial activation is done via license key entry; offline activation (HWID-based) is also supported.
  • Licensing panel in-app provides current status, remaining activations, and license re-issue.

3. Task Overview (What Can You Do with Mr.SIP Pro?)

Mr.SIP Pro empowers security professionals to simulate VoIP-specific threat scenarios, discover network and application misconfigurations, and validate infrastructure resilience using modular, task-driven workflows. Each task represents a capability designed to solve real-world testing needs.

  • Infrastructure Discovery: Identify SIP endpoints, extract version data, and map protocol behavior across IP ranges.
  • User & Auth Enumeration: Detect valid users, SIP extensions, and authentication mechanisms for targeted testing.
  • Passive Traffic Inspection: Intercept SIP and RTP flows for metadata analysis or media session monitoring.
  • Call Eavesdropping & Signal Profiling: Monitor ongoing calls, capture control-plane data, and analyze signaling patterns.
  • Vulnerability Correlation: Match service fingerprints with known CVEs, exploits, default settings, or protocol misuses.
  • Denial of Service Testing: Stress systems with bursty or persistent SIP traffic to assess overload handling.
  • Authentication & Session Weaknesses: Replay, manipulate, or brute-force SIP digest authentication flows.
  • Signaling Injection & Caller ID Spoofing: Evaluate trust boundaries through custom INVITE sequences or forged headers.
  • Advanced Attack Scenarios: Chain logical flaws or retransmission bugs to simulate multi-stage attacks.
  • Fuzzing & Protocol Robustness: Send malformed SIP requests to uncover parser-level bugs or crash conditions.
  • RTP Stream Control: Capture, inject, modify, or replay audio content in real time.
  • DTMF Capture: Intercept and decode keypad tones from live RTP sessions.
  • Robocall Simulation: Emulate SPIT (spam over IP telephony) with prerecorded calls to test anti-abuse defenses.
  • Man-in-the-Middle Injection: Combine ARP spoofing and SIP proxying for inline traffic tampering.
  • Automated Assessment: Use Auto-Deep mode to trigger comprehensive scans across modules in an orchestrated flow.

4. Architecture & Module Design

Mr.SIP Pro is built on a modular and extensible architecture designed to support scalable, task-driven VoIP security assessments. Its components are grouped into four core categories, each serving a distinct role in the evaluation pipeline.

  • 1. Information Gathering Modules: Designed to discover network-facing VoIP infrastructure, users, and signaling metadata. These modules form the reconnaissance backbone for more targeted analysis and attack simulation.
  • 2. Vulnerability & Exploit Analysis: Performs protocol-aware assessments to identify misconfigurations and known vulnerabilities. By leveraging live fingerprints and discovery insights, these modules help prioritize actionable findings.
  • 3. Offensive Simulation Modules: Focus on stress-testing SIP-based systems through controlled abuse scenarios — including signaling manipulation, denial-of-service conditions, and protocol fuzzing. These tests are aligned with real-world attack behaviors.
  • 4. Utility & Orchestration Layers: Enable automated task chaining, dynamic input generation, and result correlation across modules. This layer allows security teams to conduct both focused and full-stack assessments with minimal friction.

Rather than relying on fixed playbooks, Mr.SIP Pro supports flexible testing flows and data-aware execution. Module outputs are securely passed and correlated within the platform’s core engine — ensuring that each phase benefits from contextual awareness without exposing implementation specifics.

5. Navigating the Interface

  • Web GUI provides module selection, parameter configuration, real-time logs, and detailed results.
  • Task buttons and modals are dynamically adapted to each module’s operational scope.
  • Support for dark/light theme, custom dictionaries, and auto-saving of scan sessions.

6. Usage Scenarios

  • Red Teamers conducting VoIP attack simulations.
  • Penetration testers and consultants performing SIP/RTP protocol audits.
  • VoIP service providers validating infrastructure against robocall and SPIT abuse.
  • Researchers developing SIP security tools or fuzzing SIP stacks.
  • Telecom security engineers testing resilience against signaling-layer DDoS or media manipulation.

7. Troubleshooting & Support

  • Installation issues: Check dependency list in docs/dependencies.md.
  • No module output: Increase verbosity in Settings → Logging → Level: Debug.
  • License errors: Confirm HWID matches or contact info@vulnhero.com.
  • Custom support available for Enterprise clients via email or Slack.

8. Versioning & Updates

  • Product checks for updates automatically (can be disabled).
  • Manual update: Replace the old binary with the newly downloaded one.
  • Changelog is available under the HelpRelease Notes section in-app.
