VoIP client for Ubuntu

Having used IP Telephony for a number of years I need a workable SIP client for all of the devices I use. I have found a very capable client for my Android phones (SipDroid) and on Windows/MacOSX I generally use X-Lite (as well as it’s paid version EyePhone) from Counterpath.

Having tried several different Linux SIP clients (Ekiga, Twinkle, …) but all discarded them because of weird UI’s and/or problems with stability I noticed that there is a Linux version of XLite available. Unfortunately on current versions of Ubuntu (10.04) it needs a deprecated version of a library.

Download XLite Linux: http://www.counterpath.com/x-lite-3.0-for-linux-download.html

Dowload libstdc++.so.5: http://packages.debian.org/lenny/i386/libstdc++5/download

[you will need root permissions for all of the below]

dpkg -i libstdc++5_3.3.6-18_i386.deb
tar -xzf X-Lite_Install.tar.gz
cd xten-xlite
cp xtensoftphone /usr/sbin
chmod +x /usr/sbin/xtensoftphone
Now you should be able to run:
xtensoftphone

Enjoy calling from your Ubuntu machine !

EDIT: Since upgrading to Ubuntu 11 (Natty) I have switched to QuteCom
