This parameter allows for setting member-specific flags or parameters on individual conference members. These options include whether a participant is a moderator, whether to be wasteful with packet mixing (that is, send audio to individuals even when no speaking is happening in the conference), whether or not a specific member is the leader of a conference (and thus, the conference should terminate when they leave), and so on. Options should be separated by a pipe | character.

Parameter syntax: <param name="member-flags" value="waste|endconf"/>

Some of the options for the member-flags parameter follows. For a full list, and extended explanations, please consult our documentation online on http://freeswitch.org/confluence, searching for "mod_conference"

• moderator: Member has a different set of caller-controls, and can manage the conference: mute and unmute participants, etc
• deaf: Prevents the members from listening to other members in the conference by default (this can be changed after the conference has begun).
• waste: Sends audio to channels even when no conversation is occurring.
• dist-dtmf: Distributes DTMF signals to each channel. When someone sends a DTMF tone, it is normally absorbed and processed by FreeSWITCH. This option prevents that from happening and instead echoes the DTMF tone to all other members.
• endconf: Specifies that the conference should end when this
  member exits.
