Development version of Ekiga Softphone now sports a dazzling new contact list feature, which means there is a good chance I might actually be persuaded to keep the app running whilst I get on with my day to day things.
As evident from the screenshot, it supports contact groups, and works as you would expect. Unfortunately my contact list is rather bare at the moment, as no one else seems to use voice and video to communicate? Anyone?
If you run Ubuntu 7.04 you can try the cvs version by using the following magic deb line:
deb http://snapshots.ekiga.net/ubuntu feisty main
Before trying also note that there is a 400MB/day leak in the current svn build, so YMMV.
