VoIP monitor

VoIP monitor is packet sniffer analyzer wav recorder for SIP calls. It calculates MOS (Meaning Opinion Score) by E-model (ITU-T G.107) and stores statistics to MySQL database. Primary goal is to provide complete platform for VoIP quality measurments.


  • Saves SIP calls to WAV from G.711/G.729/G.723/GSM/iLBC/Speex
  • Calculates MOS score according to ITU-T G.107 E-model
  • Fast SIP RTP packet sniffer
  • Web application for filtering CDR and finding worst calls by MOS/Loss/Latences
  • Nice Loss/Latences graphs
  • Jitterbuffer simulator (fixed and adaptive)
  • Detects terminated calls when SIP BYE or OK is missing.

It is the first open source implementation of SIP Servlet v1.1 (JSR 289) and runs with Tomcat or JBoss AS. JSIP is leveraged as the low level SIP protocol stack.
  • Mobicents Media Server is an open source pure Java real time media server. MMS is the first open source implementation of JSR 309 (Media Server Control). MMS delivers competitive, complete, best-of-breed media gateway functionality. It is designed to meet the demands of converged wireless, wireline, cable broadband access and fixed-mobile converged VoIP networks from a single media gateway platform. MMS supports a wide variety of call control protocols and scales down to meet the demands of enterprises and small carrier providers. MMS is designed to scale reliably and predictably in cloud computing environments
  • Mobicents SIP Presence Service provides presence functionalities to SIP based networks, implementing standards from IETF, OMA, 3GPP and ETSI. It includes a XDM Server, a Presence Server, a Resource Lists Server (TBA), all implemented on top of the Mobicents JAIN SLEE core. Client access components such as JAIN SLEE SBB enablers interfaces, internal and external to the servers, are also provided.
  • Mobicents Diameter is an open source implementation of the Diameter family of protocols enabling AAA services for IMS components such as Application Server (AS), Home Subscriber Server (HSS), Call Session Control Function (CSCF), Subscriber Location Function (SLF), and others. Mobicents Diameter is easily extensible to new applications required by 3GPP or custom vendor applications.
  • Mobicents SS7 and USSD Gateway is an open source Java software stack implementing MTP2,3, ISUP, SCCP, TCAP, CAMEL, and MAP protocols for dedicated SS7 equipment such as Dialogic SS7 PC Cards. Mobicents SS7 also provides SS7 interconnectivity over IP vis M3UA (SIGTRAN).

Real time web based SIP Packet analyzer

In this project a real time VoIP signaling analyzer and alarming system was developed which deals with SIP signaling. . The popular C library WinPcap was used to build up the program. The packets were stored in MySQL database through MySQL shell.

Documentation & Presentation :


  • SIP packet capture
  • Captured packets are inserted into mysql database
  • real-time packet tracing using AJAX
  • PHP based web reporting interface

Sipvicious V 0.2.7 released

SIPVicious suite is a set of tools that can be used to audit SIP based VoIP systems.

Changelog For V-0.2.7 :

  • Feature: svcrash.py has a new option -b which bruteforces the attacker’s port
  • Feature: svcrack.py now tries the extension as password by default, automatically
  • Feature: svcrack.py and svwar.py now support setting of source port
  • Feature: new parameter –domain can be passed to all tools which specifies a custom domain in the SIP uri instead of the destination IP
  • Feature: new –debug switch which shows the messages recieved
  • Bug fix: Sometimes nonces could not be extracted due to an incorrect regex
  • Bug fix: Fixed an unhandled exception when decoding tags
  • Bug fix: now using hashlib when available instead of md5
  • Bug fix: removed the space after the SIP address in the From header which led to newer version of Asterisk to ignore the SIP messages
  • Bug fix: dictionaries with new lines made svcrack.py stop without this fix
  • Change: renamed everything to start with sv
  • Bug fix: changed the way shelved files are opened by the fingerprinting module
  • Change: fingerprinting disabled by default since it was giving too many problems and very little benefits

VPND – Virtual Private Network Daemon

vpnd is a daemon which connects two networks on network level either via TCP/IP or a (virtual) leased line attached to a serial interface. All data transfered between the two networks are encrypted using the unpatented free Blowfish encryption algorithm with a key length of up to 576 bits (may be downgraded to a minimum of 0 bits to suit any legal restrictions)

Release Notes v1.1.4 : More configuration options, VoIP optimizations for SIP phones, and minor fixes.

VoIP Hopper 2.01 Released – IP Phone VLAN Hopping Tool

VoIP Hopper 2.01 Released – IP Phone VLAN Hopping Tool

VoIP Hopper is a GPLv3 licensed security tool, written in C, that rapidly runs a VLAN Hop into the Voice VLAN on specific ethernet switches. VoIP Hopper does this by mimicking the behavior of an IP Phone, in Cisco, Avaya, and Nortel environments.

This requires two important steps in order for the tool to traverse VLANs for unauthorized access. First, discovery of the correct 12 bit Voice VLAN ID (VVID) used by the IP Phones is required. VoIP Hopper supports multiple protocol discovery methods (CDP, DHCP, LLDP-MED, 802.1q ARP) for this important first step. Second, the tool creates a virtual VoIP ethernet interface on the OS. It then inserts a spoofed 4-byte 802.1q vlan header containing the 12 bit VVID into a spoofed DHCP request.

Once it receives an IP address in the VoIP VLAN subnet, all subsequent ethernet frames are “tagged” with the spoofed 802.1q header.

VoIP Hopper is a VLAN Hop test tool but also a tool to test VoIP infrastructure security.

New Features

  • New “Assessment” mode: Interactive, menu driven command interface, improves ability to VLAN Hop in Pentesting when the security tester is working against an unknown network infrastructure
  • New VLAN Discovery methods (802.1q ARP, LLDP-MED)
  • LLDP-MED spoofing and sniffing support
  • Can bypass VoIP VLAN subnets that have DHCP disabled, and spoof the IP address and MAC address of a phone by setting a static IP

  • svwar – identifies active extensions on a PBX
  • svcrack – an online password cracker for SIP PBX
  • svreport – manages sessions and exports reports to various formats
  • svcrash – attempts to stop unauthorized svwar and svcrack scans



SIPVicious works on any system that supports python 2.4 or greater.

Operating System

It was tested on the following systems:

Mac OS X
FreeBSD 6.2
Jailbroken iPhone with python installed

If you use it on systems that are not mentioned here please let me know goes it goes.
