[general]
; The general section of this config
; is not currently used, but reserved
; for future use.

;
; --- Default Information ---
; The default_user and default_bridge sections are applied
; automatically to all ConfBridge instances invoked without
; a user, or bridge argument.  No menu is applied by default.
;
; Note that while properties of the default_user or default_bridge
; profile can be overridden, if removed, they will be automatically
; added and made available to the dialplan upon module load.

;denoise=yes ; Sets whether or not a denoise filter should be applied

;jitterbuffer=yes  ; Enabling this option places a jitterbuffer on the user's audio stream
                   ; before audio mixing is performed.  This is highly recommended but will
                   ; add a slight delay to the audio.  This option is using the JITTERBUFFER

;pin=1234  ; Sets if this user must enter a PIN number before entering
           ; the conference.  The PIN will be prompted for.
;announce_join_leave=yes ; When enabled, this option will prompt the user for a

;dtmf_passthrough=yes  ; Sets whether or not DTMF should pass through the conference.

;record_file=</path/to/file>   ; When record_conference is set to yes, the specific name of the
                               ; record file can be set using this option.  Note that since multiple

                               ; depending on the configuration.  It is recommended to only use this
                               ; option dynamically with the CONFBRIDGE() dialplan function. This

                        ; larger amounts of delay into the bridge.  Valid values here are 10, 20, 40,
                        ; or 80.  By default 20ms is used.

;video_mode = follow_talker; Sets how confbridge handles video distribution to the conference participants.

                           ; with the video.  This is a result of the jitterbuffer only working on the audio
                           ; stream.  It is recommended to disable the jitterbuffer when video is used.

; --- ConfBridge Menu Options ---
; The ConfBridge application also has the ability to
; apply custom DTMF menus to each channel using the
; application.  Like the User and Bridge profiles
; a menu is passed in to ConfBridge as an argument in
; the dialplan.
;
; Below is a list of menu actions that can be assigned
; to a DTMF sequence.
;
; To have the first DTMF digit in a sequence be the '#' character, you need to
; escape it.  If it is not escaped then normal config file processing will
; think it is a directive like #include.  For example:
; \#1=toggle_mute                      ; Pressing #1 will toggle the mute setting.
;
; A single DTMF sequence can have multiple actions associated with it. This is
; accomplished by stringing the actions together and using a ',' as the delimiter.
; Example:  Both listening and talking volume is reset when '5' is pressed.
; 5=reset_talking_volume, reset_listening_volume
;
