H323 analysis
Client possibilities
For some possible H323 (and SIP) VoIP clients you can check this list The only two that support both H323 and linux are:
Ekiga
If it were to work the interface is supposed to look like this To be downloaded from the ekiga page. Unfortunately the packages OPAL and PWLIB libraries have to be installed first. This is a tedious and time comsuming process (lots of compiling needed). When we were finally done with this we tried to configure ekiga but we got the error message: Package gnome-doc-utils was not found in the pkg-config search path. We gave up since no system manager was available at this moment and decided to go on exploring the SJPhone option first.
SJPhone
Very straightforward download from SJ Labs (VoIP software). You get the following interface.
We tried to reach our TrixBox but no connection was established.
