Hi, I'm new to FreeSwitch and starting to experiment with conferences. I've browsed the wiki and I'm half way through the ebook and I'm running into a few questions I'm hoping I might be able to get some help with. 1. How do I translate conference cli commands (e.g. "conference xxx mute yyy") into a dialplan xml actions? 2. The default behavior of the conference is to disable hold music and allow the participants to speak when there are two or more callers. How might I keep the conference on hold until a particular caller joins? Additionally when this special user leaves I'd like to place the conference back on hold. 3. Where might I find info regarding loading configuration information (particularly the user directory) from an external source (probably a database and probably via mod_python)? 4. I'd like to have some private conferences that only certain callers can join. I'll know the callers' ids before hand. I'm assuming a reasonable way to handle is with user groups. How would I test if a user is a member of a particular group? Thanks, -Matt
