TransferHTTP: A SIP Integrated Web Browser for HTTP Session Mobility and Multimedia Services

Artemisa is a VoIP/SIP-specific honeypot software designed to connect to a VoIP enterprise domain as a user-agent backend in order to detect malicious activity at an early stage. Moreover, the honeypot can play a role in the real-time adjustment of the security policies of the enterprise domain where it is deployed.

Artemisa uses the Python module provided by PJSIP

This SIP softphone is written in Java as an eclipse RCP application. It uses the pjsip SIP stack for connecting to SIP servers. The phone runs on Windows and Linux. It would run on Mac OS too, but manually compiling it is necessary because of the JNI bindings to pjsip. The Java-JNI binding which are used by the phone are hosted on sourceforge.net, but are currently included in the SVN tree.

The Host Identity Protocol (HIP) and the related architecture form a proposal to change the TCP/IP stack to securely support mobility and multi-homing. Additionally, they provide for enhanced security and privacy and advanced network concepts, such as moving networks and mobile ad hoc networks. The InfraHIP project studies application related aspects of HIP, including APIs, rendezvous service, operating system security, multiple end-points within a single host, process migration, and issues related to enterprise-level solutions.

Network-emulator is a simple utility intended to test how network losses affects speech quality in VoIP-based applications. Experimenter can set up loss rate, bandwidth, encoder options and select one of the packet loss suppression algorithm.

Emulator can help quickly obtain these measures:

• compare encoding quality for different codecs and codecs modes.
• estimate the impact of the loss level and distribution on the speech quality.
• estimate the impact of the different PLC algorithms on the speech quality.

Open Peer-to-Peer VoIP and IM System

OpenVoIP is "an open source peer-to-peer VoIP and IM system of ~1000 nodes running on ~300 PlanetLab machines. OpenVoIP runs Peer-to-Peer Protocol (P2PP) which can be used to implement well-known DHTs or unstructured protocols. Unlike OpenDHT, where it was only possible to put/get the data, we allow non-PlanetLab nodes to become part of our overlay".

The OpenVoIP project uses STUN, TURN, and ICE features in PJNATH for its NAT traversal.

Open Peer-to-Peer VoIP and IM System

SIP SIMPLE client is Python software library built on top of PJSIP that together with middleware allows for easy development of Internet communications end-points based on SIP and related protocols for voice, rich presence, instant messaging (IM) and file transfers. Other session types can be easily added by using an extensible API.

SIP softphone, also a simple and small SDK to develop VoIP applications in Python.

YASS began as a university project, and has been released to the public. Apart from being a SIP softphone, YASS pretends to be a simple and small SDK to develop VoIP applications in Python. It's based on PJSIP's pjsua Python bindings for the core and the Qt4 libraries for the GUI part. Communication between the core and the GUI is made through callbacks, so it's completely detached.
