Jabber is the only mainstream free (as in speech) instant messaging protocol. Unfortunately, most Jabber clients for GNU/Linux only provide options for messaging and group chats, overlooking the audio chatting portion of Jabber (powered by the Google-funded libjingle). Enter Jabbin, the free Qt-based Jabber VoIP client.
My children recently started school. I wanted a way for them to be ableto chat with their friends, get help with homework, and generally have funon the Internet without exposing them to the world at large. So, I did whatany extremely geeky dad would do: I built a secured instant messaging (IM)server for their school.
I could have set my children up with any number of accounts on thenormal, commercial services. However, I decided to create my own forseveral reasons.
