GNU SIP Witch is a call and registration server for the SIP protocol. As a call server it services call registration for SIP devices and destination routing through SIP gateways.
GNU SIP Witch supports using secure telephone extensions, for placing and receiving b2b calls directly over the internet, and intercept/decrypt-free peer-to-peer audio and video extensions.
The initial public release of GNU SIP Witch (0.1.0) offers support of SIP registration, multi-target registration, authentication peering over SIP, registration querying of user agents, basic call processing between registered user agents only including call distribution for multi-target registrations, and basic SIP instant messaging between registered extensions.
GNU SIP Witch is not a SIP "router", and does not try to address the same things as a project like iptel "Ser".
GNU SIP Witch is being designed to create on-premise SIP telephone systems, telecenter servers, and Internet hosted SIP telephone systems.
GNU SIP Witch depends on the UCommon library, which may merge with and become GNU Common C++ 2.0 later this year or early next year. CVS for and new distributions of UCommon will be found in the GNU Telecom project on an interim basis until then.
GNU SIP Witch also uses libeXosip2 and GNU oSIP, and these may be found at their respective sites.

Enhancements
- SIP publish can be forwarded through plugins. Forward plugin publishes status to insecure calling domain.

GNU TeXmacs is a free wysiwyw (what you see is what you want) editing platform with special features for scientists.
The software aims to provide a unified and user friendly framework for editing structured documents with different types of content (text, graphics, mathematics, interactive content, etc.).
The rendering engine uses high-quality typesetting algorithms so as to produce professionally looking documents, which can either be printed out or presented from a laptop.
The software includes a text editor with support for mathematical formulas, a small technical picture editor and a tool for making presentations from a laptop. Moreover, TeXmacs can be used as an interface for many external systems for computer algebra, numerical analysis, statistics, etc.
New presentation styles can be written by the user and new features can be added to the editor using the Scheme extension language. A native spreadsheet and tools for collaborative authoring are planned for later.
TeXmacs runs on all major Unix platforms and Windows. Documents can be saved in TeXmacs, Xml or Scheme format and printed as Postscript or Pdf files. Converters exist for TeX/LaTeX and Html/Mathml.
TeXmacs currently runs on most Unix systems, Mac OS X (using Fink), and Windows (using Cygwin).
System requirements:
- 200MHz processor and 32Mb of memory, but >1GHz and >128Mb are recommended.
- TeX/LaTeX distribution on your system
- Guile/Scheme extension language (to compile TeXmacs from source)
