Linphone is a free (as in speech, GPLv2), open source Voice over IP (VoIP) software for Linux, Windows, MacOSX as well as Android, iPhone and Blackberry. It is a secure, encrypted, standards compliant alternative to proprietary alternatives like Skype.
The latest version of Linphone, as of this writing, is 3.7.0. This version is not available in the Debian Wheezy repositories, which have v3.5.2. That version lacks some features of 3.7.0, like integrated text messaging.
This guide explains how to compile linphone version 3.7.0 on Wheezy, with strong encryption support.
Sources: These instructions were prepared from the README file in the linphone sources and this blog post.
- Install all the linphone dependencies which we can from the debian repositories
sudo apt-get install libtool intltool libgtk2.0-dev libspeexdsp-dev libavcodec-dev libswscale-dev libx11-dev libxv-dev libgl1-mesa-dev libglew1.6-dev libv4l-dev libxml2-dev libvpx-dev libasound2-dev libpulse-dev libpolarssl-dev antlr3 libantlr3c-dev libreadline-dev libgsm1-dev libtheora-dev libsoup2.4-dev libsqlite3-dev libupnp6-dev libx264-dev cmake
- Install srtp for call encryption
git clone git://git.linphone.org/srtp.git
cd srtp && autoconf && ./configure && make
sudo make install
git clone git://git.linphone.org/belle-sip
cd belle-sip
git checkout tags/1.3.0
./autogen.sh
./configure --enable-tls
make
sudo make install
- Install zrtpcpp for unbreakable call encryption
git clone https://github.com/wernerd/ZRTPCPP.git
cd ZRTPCPP
cmake -DCORE_LIB=true -DSDES=false . && make
sudo make install
- Download and install linphone 3.7.0
wget http://download-mirror.savannah.gnu.org/releases/linphone/3.7.x/sources/linphone-3.7.0.tar.gz
tar zxvf linphone-3.7.0.tar.gz
cd linphone-3.7.0
./configure --enable-ipv6 --enable-alsa --enable-zrtp
make
sudo make install
sudo ldconfig
- To compile the h264 video plugin
git clone git://git.linphone.org/msx264.git
cd msx264
./autogen.sh
./configure
make
sudo make install
UPDATE: 2014-08-24
A kind reader, Karsten (fk021772@gmx.de), sent an email with these instructions for compiling the G729 codec:
git clone git://git.linphone.org/bcg729.git
cd bcg729
./autogen.sh
./configure
make
make install
## enable G729 plugin in Linphone settings->Codec and shift it on top.
## if you use TLS you need to change the following in settings file:
[sip]
verify_server_certs=0
