Ubuntu (specially 8.10 Intrepid Ibex) comes with a very old version of Ekiga Softphone. In order to solve this we have a personal site at Launchpad, the PPA for Troels Liebe Bentsen.

Just follow the instructions described in this page: http://wiki.ekiga.org/index.php/Snapshots at the bottom of the page under the title “Ubuntu”.

Beware to use the information found at the PPA for Troels Liebe Bentsen page. That is:

1) the repository information for your Ubuntu version (for Intrepid use: deb http://ppa.launchpad.net/tlbdk/ppa/ubuntu intrepid main & deb-src http://ppa.launchpad.net/tlbdk/ppa/ubuntu intrepid main)

2) the repository signature found here.
