[Freeswitch-users] Conference members variable

Hi Everybody I am building a conferencing service, and I was wondering if there is a system variable that I can use, that holds the number of members in a specific conference. Is there a variable I can read (in java, or anywhere) that tells me this ? If there is, is there a list of FreeSWITCH variables anywhere ? I can read the members (and the total) via CLI (conference <conference> list), but I don't know how to "import" this figure to my (java)script. Thank you very much for your time Torstein
