LibiLBC is a packaging friendly copy of the iLBC codec from the WebRTC project. It provides a base for distribution packages and can be used as drop-in replacement for the non-free code from RFC 3591.

Mumble is an low-latency, high quality voice chat software primarily intended for use while gaming. Mumble consists of two applications for separate usage: mumble for the client, and murmur for the server.

GNU ccRTP is an implementation of RTP, the real-time transport protocol from the IETF. It is suitable both for high capacity servers and personal client applications. It is flexible in its design, allowing it to function as a framework for the framework, rather than just being a packet-manipulation library.

GNU oSIP is an implementation of the SIP protocol. It is used to provide multimedia and telecom software developers with an interface to initiate and control SIP sessions.

SpanDSP is a library of DSP functions for telephony, in the 8000 sample per second world of E1s, T1s, and higher order PCM channels. It contains low level functions, such as basic filters. It also contains higher level functions, such as cadenced supervisory tone detection, and a complete software FAX machine.

GNU SIP Witch is a peer-to-peer Voice-over-IP server that uses the SIP protocol. Calls can be made from behind NAT firewalls and without the need for a service provider. Its peer-to-peer design ensures that there is no central point for media intercept or capture and thus it can be used to construct a secure telephone system that operates over the public internet.

Libre is a portable and generic library for real-time communications with async IO support and a complete SIP stack with support for protocols such as SDP, RTP/RTCP, STUN/TURN/ICE, BFCP, HTTP and DNS.

LibIAX2 implements the Inter-Asterisk-Protocol for relaying Voice-over-IP (VoIP) communications.

xgoldmon is an utility that converts the USB logging mode messages that various Intel/Infineon XGold modems send to the USB port to gsmtap. It then then sends them to a given IP address to enable users to view cellular network protocol traces in Wireshark.

It supports the following smartphones:

• Samsung Galaxy S4, GT-I9500 variant

• Samsung Galaxy SIII, GT-I9300 variant

• Samsung Galaxy Nexus, GT-I9250 variant

• Samsung Galaxy SII, GT-I9100 variant

• Samsung Galaxy Note II, GT-N7100 variant

GNU Common C++ is an portable, optimized class framework for threaded applications, supporting concurrent synchronization, inter-process communications via sockets, and various methods for data handling, such as serialization and XML parsing. It includes the uCommon C++ library, a smaller reimplementation.

GNU ZRTP C++ provides a library that adds ZRTP support to the GNU ccRTP stack and serves as library for other RTP stacks (PJSIP, GStreamer).

SIPp can be used to test many real SIP equipements like SIP proxies, B2BUAs, SIP media servers, SIP/x gateways, and SIP PBXes. It is also very useful to emulate thousands of user agents calling your SIP system.

Sofia-SIP is a SIP User-Agent library, compliant with the IETF RFC3261 specification. It can be used as a building block for SIP client software foruses such as VoIP, IM, and many other real-time and person-to-person communication services.

Alacritty is a GPU-accelerated terminal emulator with a strong focus on simplicity and performance. With such a strong focus on performance, included features are carefully considered and you can always expect Alacritty to be blazingly fast. By making sane choices for defaults, Alacritty requires no additional setup. However, it does allow configuration of many aspects of the terminal. Note that you need support for OpenGL 3.2 or higher.

This package provides a terminal emulator with hyperlink support. It's based on VTE and aimed at power users.

Havoc is a minimal terminal emulator for Wayland.

Libvterm is an abstract C99 library which implements a VT220 or xterm-like terminal emulator. It doesn't use any particular graphics toolkit or output system, instead it invokes callback function pointers that its embedding program should provide it to draw on its behalf. It avoids calling malloc during normal running state, allowing it to be used in embedded kernel situations.

foot is a terminal emulator for systems using the Wayland display server. It is designed to be fast, lightweight, and independent of desktop environments. It can be used as a standalone terminal and also has a server/client mode.

This package provides an interactive command-line filter usable with any list--including files, command history, processes and more.

Tilda is a terminal emulator similar to normal terminals like gnome-terminal (GNOME) or Konsole (KDE), with the difference that it drops down from the edge of a screen when a certain configurable hotkey is pressed. This is similar to the built-in consoles in some applications. Tilda is highly configurable through a graphical wizard.

mlterm is a multi-lingual terminal emulator. It supports various complex character sets and encodings from around the world. It can display double-width (e.g. East Asian) glyphs, combining characters used for, e.g., Thai and Vietnamese, and bi-directional scripts like Arabic and Hebrew.

Bootterm is a terminal designed to ease connection to ephemeral serial ports. It features automatic port detection, port enumeration, support for non-standard baud rates, the ability to wait for ports to appear, and the ability to read and write via stdin and stdout.

Kmscon is a terminal emulator based on Linux's kernel mode setting (KMS). It can replace the in-kernel virtual terminal (VT) implementation with a user-space console. Compared to the Linux console, kmscon provides enhanced features including XKB-compatible internationalized keyboard support, UTF-8 input/font support, hardware-accelerated rendering, multi-seat support, a replacement for mingetty, and more.
