HOWTO: Make google talk voice calls

[chiefofthejojos]

This post will show you how to install a program on ubuntu which can actually make voice calls to other google talk users. Unfortunately, it's not in a stable version yet so we will have to compile the source. This is a development branch of the psi jabber client, being called psi-jingle.

First, lets satisfy some dependancies. NOTE: The universe repository needs to be enabled.

sudo apt-get install darcs speex libspeex-dev libqt3-mt-dev qt3-dev-tools qca-tls qca-dev libqca1c2 libasound2-dev libglib2.0-dev build-essential

There's one more that needs to be compiled and installed by hand. NOTE: currently you must use version 0.7.1 of libortp or it won't work.

wget http://linphone.org/ortp/sources/ortp-0.7.1.tar.gz
tar zxvf ortp-0.7.1.tar.gz && rm ortp-0.7.1.tar.gz
cd ortp-0.7.1
./configure
make
sudo make install
sudo ln -s /usr/local/lib/libortp.so.0 /usr/lib/libortp.so.0

Now, get and compile psi-jingle. NOTE: The --enable-jingle option must be present if you want to make voice calls.

darcs get --partial --set-scripts-executable http://dev.psi-im.org/darcs/psi-jingle
cd psi-jingle
./configure --with-ortp-inc=/usr/local/include/ --enable-jingle
make
sudo make install

Good luck!
