Hello list, I am trying to set up our conferencing system to pull some preferences from a database. In the conference.conf.xml file, I have a few profiles that cover pretty much all the bases, but I want to be able to set the music on hold sound differently for each conference, without reloading XML. I tried using ${hold_music} as the moh_sound in the config file, but this doesn't seem to expand. Is there a way to dynamically set conference profile options with a channel variable? I read a bit on generating config with LUA. The wiki talks about dialplan and directory, but doesn't really say much about other module configs. Can I bind a lua script to mod_conference? Can someone give me a snippet of that binding if that's possible? Thanks for the help! -Tim
