Bcmatroska2 is a C library to parse Matroska files (.mkv and .mka).

Bcg729 is an implementation of both encoder and decoder of the ITU
G.729 Annex A/B speech codec. It supports concurrent channels
encoding/decoding for multi call application such as conferencing.

Utilities library used by Belledonne Communications softwares like belle-sip, mediastreamer2 and linphone.

Belcard is a C++ library to manipulate the vCard standard format files.

belle-sip is a SIP (RFC3261) implementation written in C, with an object oriented API.

Belr parses input formatted according to a language defined by an ABNF grammar, such as the protocols standardised at IETF.

BroadVoice is a family of speech coding algorithms created by Broadcom and standardized by CableLabs, SCTE, and ANSI for Voice over IP applications in cable telephony. BroadVoice is also part of the ITU-T Recommendations J.161 and J.361.

bzrtp is a FOSS implementation of ZRTP keys exchange protocol.
The library written in C 89, is fully portable, and can be executed
on many platforms including x86 and ARM processors.

LIME is an encryption library for one-to-one and group instant messaging, allowing users to exchange messages privately and asynchronously. It supports multiple devices per user and multiple users per device.

LIME offers two major security benefits to instant messaging users:
* End-to-end encryption, which means that only you and your contact (and not even the server) can decrypt the content that you shared.
* Perfect forward secrecy, which ensures that encrypted messages cannot be decrypted by a third party, even if a key is compromised in the future.

Linphone is a Web phone with a Qt interface.
It lets you make two-party calls over IP networks such as the Internet.
It uses the IETF protocols SIP (Session Initiation Protocol) and RTP (Real-time Transport Protocol) to make calls, so it should be able to communicate with other SIP-based Web phones. With several codecs available, it can be used with high speed connections as well as 28k modems.
