Bo GnuGk fully supports H.239 (most gatekeepers do) and can be used with H323plus to do H.239. You can do H.239 with or without a gatekeeper.

Thanks! Hello Simon, Thanks! could you also tell me if I want to make a H.239-enabled call with H323Plus terminal, do I also need a H.239-enabled gate-keeper? or I can use one H323Plus to make a H.239-enabled call to another H323plus directly? Thanks! also could you tell me if GnuGK supports H.239? Thanks!
