• Multiple call management (pause and resume)

• Call transfer

• Audio conferencing (merge calls into a conference call)

• Call recording and replay (audio only)

• Instant Messaging with message delivery status (IMDN)

• Picture and file sharing

• Echo cancellation

• Secure user authentication using TLS client certificates

• SRTP, zRTP and SRTP-DTLS voice and video encryption

• Telephone tone (DTMF) support using SIP INFO or RFC 4733

• Audio codecs: opus, speex, g711, g729, gsm, iLBC, g722, SILK, etc.

• Video codecs: VP8, H.264 and H.265 with resolutions up to 1080P, MPEG4

MSAMR is a plugin of MediaStreamer, adding support for AMR codec. It is based on the opencore-amr implementation.

Mediastreamer2 is a powerful and lightweight streaming engine for telephony applications. This media processing and streaming toolkit is responsible for receiving and sending all multimedia streams in Linphone, including media capture, encoding and decoding, and rendering.

BCUnit is a fork of the defunct project CUnit, with several fixes and patches applied. It is a unit testing framework for writing, administering, and running unit tests in C.

MSWebRTC is a plugin of MediaStreamer, adding support for WebRTC codec. It includes features from WebRTC, such as, iSAC and AECM.

BcToolBox is an utilities library used by Belledonne Communications software like belle-sip, mediastreamer2 and linphone.

Liblinphone is a high-level SIP library integrating all calling and instant messaging features into an unified easy-to-use API. It is the cross-platform VoIP library on which the Linphone application is based on, and that anyone can use to add audio and video calls or instant messaging capabilities to an application.

Belle-sip is a modern library implementing SIP transport, transaction and dialog layers. It is written in C, with an object-oriented API. It also comprises a simple HTTP/HTTPS client implementation.

BcG729 is an implementation of both encoder and decoder of the ITU G729 speech codec. The library written in C 99 is fully portable and can be executed on many platforms including both ARM and x86 processors. It supports concurrent channels encoding and decoding for multi call application such as conferencing.

BZRTP is an implementation of ZRTP keys exchange protocol, written in C. It is fully portable and can be executed on many platforms including both ARM and x86.

MsOpenH264 is an H.264 encoder/decoder plugin for mediastreamer2 based on the openh264 library.

pflask is a simple tool for creating Linux namespace containers. It can be used for running a command or even booting an OS inside an isolated container, created with the help of Linux namespaces. It is similar in functionality to chroot, although pflask provides better isolation thanks to the use of namespaces.

Headers of the Linux-Libre kernel.

Kmod is a set of tools to handle common tasks with Linux kernel modules like insert, remove, list, check properties, resolve dependencies and aliases.

These tools are designed on top of libkmod, a library that is shipped with kmod. The aim is to be compatible with tools, configurations and indices from the module-init-tools project.

libnetfilter_log is a userspace library providing interface to packets that have been logged by the kernel packet filter. It is is part of a system that deprecates the old syslog/dmesg based packet logging. This library has been previously known as libnfnetlink_log.

1. receiving to-be-logged packets from the kernel nfnetlink_log subsystem

kernel-hardening-checker is a tool for checking the security hardening options of the Linux kernel. Provided preferences are based on suggestions from various sources, including:

• KSPP recommended settings

• CLIP OS kernel configuration

• Last public grsecurity patch (options which they disable)

• SECURITY_LOCKDOWN_LSM patchset

• Direct feedback from the Linux kernel maintainers

This tool supports checking Kconfig options and kernel cmdline parameters.

Keyd is a keyboard remapping utility with intuitive ini configuration file format. Keyd has several features, many of which are traditionally only found in custom keyboard firmware like QMK.

ddate displays the Discordian date and holidays of a given date. The Discordian calendar was made popular by the "Illuminatus!" trilogy by Robert Shea and Robert Anton Wilson.

This package contains keytable files and keyboard utilities compatible for systems using the Linux kernel. This includes commands such as loadkeys, setfont, kbdinfo, and chvt.

The libnl suite is a collection of libraries providing APIs to netlink protocol based Linux kernel interfaces. Netlink is an IPC mechanism primarily between the kernel and user space processes. It was designed to be a more flexible successor to ioctl to provide mainly networking related kernel configuration and monitoring interfaces.

iucode_tool is a utility to work with microcode packages for Intel processors. It can convert between formats, extract specific versions, create a firmware image suitable for the Linux kernel, and more.

Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, seccomp-bpf and Linux capabilities. The software includes sandbox profiles for a number of common Linux programs. Firejail should be added to the list of setuid programs in the system configuration to work properly.

This package provides hardware definitions and C headers for use by the Linux driver and by user-space applications for the Cassini/Slingshot high-speed network interconnect made by HPE (formerly Cray). User-land software uses cxi_prov_hw.h from this package.
