Well, http://ekiga.org/ekiga-softphone-features#audio_codecs http://ekiga.org/ekiga-softphone-features#audio_codecs and http://ekiga.org/ekiga-softphone-features#video_codecs http://ekiga.org/ekiga-softphone-features#video_codecs might change your mind. You can choose between these codecs and speex is particularly good. Not only that, it uses less CPU than skype. I often find audio and video quality of ekiga superior to skype. It's understandable that it might be difficult to convince someone to switch, as the other side must have a sip account and skype account creation is particularly easy, but in terms of audio and video quality, I think ekiga wins, specially the latest versions. I also run a private mumble server which uses speex and the audio quality is amazing, only limited by the available bandwidth.
