Hello All,
I am absolutely new to voice communication via IP but have a
requirement to setup a teacher-to-student voice communication
capability in a thin client system. I am currently using K12LTSP 5EL
(Centos5) in a development testbed that will eventually be put into
production in a learning lab. I use fl_teachertool to maintain visual
contact with the desktop of each connected terminal client (TC).
fl_teachertool also allows me to take control (mouse and keyboard and
desktop) of any terminal client if I need to demonstrate a task or
application to a student. What I would like to be able to do is allow
the teacher to communicate with any individual student via headphone
and microphone.
Also, I need to keep the system completely self-contained. That is, I
can not require the system to depend on any type of outside
switchboard or voip service provider.
Could someone please point me the in proper direction for how to
design and build this system?
Regards,
Murrah Boswell
You could look into using jabber(XMPP)+jingle(the standard, not
necessarily google's libjingle) for that. It would allow for text, voice
and probably even video. It can be run completely selfcontained, you'd
just need a jabber server. Where I'd see the bigger problem is the
client side. There are very few clients that can do voice and probably
fewer that do video and I don't know how much user interaction would be
required with the clients as they are. As far as I know the most likely
to work framework/client is telepathy/empathy which is sadly tied to
gnome.
HTH,
