Introduction

War dialing, also known as wardialing, is a technique of automatically calling telephone numbers (in a given range) to discover modems, fax machines, PBX systems, or other devices that respond to calls. Wikipedia+2Wikipedia+2 Historically used in the 1980s and 1990s, modern versions use VoIP or SIP trunks instead of analog modems. md3v.com+2Wikipedia+2

This blog will cover:

• What is war dialing, its history and purpose

• Key war dialing tools (open source and legacy)

• Practical setup using VoIP or modems

• Step-by-step usage and examples

• Legal/ethical issues and best practices

• Hindi translation for bilingual publication

What Is War Dialing? (Concept & History)

War dialing involves systematically dialing a list or range of phone numbers to detect which numbers respond with modems or data lines rather than human voice. Wikipedia+2Wikipedia+2 The objective is to find exposed systems that can be exploited or studied.

• The name “war dialing” was popularized by the movie WarGames. Wikipedia

• In early days, tools would dial sequential numbers (or randomized) using analog modems (demon dialing) to detect carrier tones. Wikipedia+2Wikipedia+2

• Modern tools often operate over VoIP or SIP, not analog lines. WarVOX is one such example. md3v.com+1

Why Use War Dialing?

• To audit telephone infrastructure and detect unauthorized modems/faxes in an organization

• To discover legacy systems connected to PSTN (public switched telephone network)

• In security assessments of telephony networks

• For research and forensic reasons

Key War Dialing / Wardialing Tools

Here are noteworthy tools (past and present) used for war dialing and telephony scanning:

---

Setting up for Practical Use

To practically use war dialing tools, you need:

1. Access to a telephony trunk / VoIP provider

   • A SIP/VoIP account with outbound dialing capability to the telephone network

   • Sometimes a VoIP to PSTN gateway

2. Modem or serial device (if using analog approach)

   • RS-232 modem connected to phone line

   • Correct configuration (baud rate, parity, etc.)

3. Tool installation & dependencies

   • E.g., WarVOX installation on Linux

   • iWar compilation/configuration

4. Dial range & number list

   • Define number ranges (area code + exchange + last n digits)

   • Exclusion lists for known numbers

5. Logging & classification setup

   • Save logs of answered numbers

   • Audio capture (if available)

   • Banner detection (if device responds with data handshake)

Practical Examples / Commands

Example A: WarVOX (VoIP-based war dialing)

WarVOX does not require an analog modem; it uses VoIP to dial numbers and analyze audio responses. Wikipedia+1

Typical usage (example):

# This is conceptual. WarVOX uses UI / CLI interfaces.
warvox --range 5551000-5551999 --provider sip_provider_conf

WarVOX classifies lines into types like fax, voicemail, modem, IVR, loops, etc., based on audio patterns. Wikipedia

Example B: iWar (Analog / Modem dialing)

Once iWar is installed:

iwar --range 18005550000-18005550999 --device /dev/ttyUSB0 --speed 115200

Parameters:

• --range: dialing number range

• --device: serial device (modem interface)

• --speed: baud rate

• iWar supports random/sequential dialing, banner detection, logging. GitHub

Example C: ToneLoc (Historical / DOS)

ToneLoc scanning invoked on DOS / emulator environment:

toneloc

ToneLoc uses carrier detection and early hangups to speed scanning. Wikipedia

Hands-On War Dialing Exercises

Important: Only perform these exercises in a lab or environment for which you have explicit permission. Do not scan real public phone numbers without legal authorization.

1. Lab Setup with VoIP Trunk

   • Obtain a VoIP provider with outgoing PSTN dialing

   • Configure a softphone or war dialing tool (WarVOX)

   • Define a small dialing range (e.g. 5551000–5551100)

   • Run WarVOX and observe classification of modems or voicemail lines

2. Analog Modem Scanning with iWar

   • Connect a modem to a phone line

   • Use iWar to dial a small local exchange

   • Log numbers that respond with carrier tones

3. Audio Analysis

   • Record call audio and classify responses:

     • Silence / hang up

     • Voice greeting

     • Fax / modem handshake

     • PBX menus

4. Exclusion & Blacklist

   • Configure your tool to skip certain numbers (e.g. emergency lines)

   • Manage “interesting numbers” separately

5. Resumable Sessions & State Saving

   • Use state save/load features in iWar

   • Pause and resume dialing without re-dialing all numbers

Legal, Ethical & Safety Considerations

War dialing can be legally sensitive or outright illegal in many jurisdictions. Key points:

• Always have written permission before scanning phone lines

• Avoid dialing emergency numbers or personal lines

• Respect privacy laws concerning audio recording and data

• Many telecom providers consider mass dialing as harassment or abuse

• Use low rate dialing and respect “Do Not Call” lists

• In corporate settings, war dialing may reveal internal security gaps—handle responsibly

Pros & Cons of War Dialing

Pros:

• Reveals hidden modems, fax machines, PBX systems

• Useful in telephony security audits

• Can uncover legacy systems not detected by IP scanning

Cons:

• Requires telephony infrastructure (modems or VoIP)

• Many numbers are human answered or dead lines → noise

• Detection and blocking by telecom providers

• Legal/ethical risks

• Time-intensive to classify responses
