||||||
|
; entering into the bridge. Enabling this option will drastically
|
||||||
|
; improve performance and help remove the buildup of background
|
||||||
|
; noise from the conference. Highly recommended for large conferences
|
||||||
|
; due to its performance enhancements.
|
||||||
|
|
||||||
|
;dsp_talking_threshold=128 ; The time in milliseconds of sound above what the dsp has
|
||||||
|
; established as base line silence for a user before a user
|
||||||
|
; is considered to be talking. This value affects several
|
||||||
|
; operations and should not be changed unless the impact on
|
||||||
|
; call quality is fully understood.
|
||||||
|
;
|
||||||
|
; What this value affects internally:
|
||||||
|
;
|
||||||
|
; 1. Audio is only mixed out of a user's incoming audio stream
|
||||||
|
; if talking is detected. If this value is set too
|
||||||
|
; loose the user will hear themselves briefly each
|
||||||
|
; time they begin talking until the dsp has time to
|
||||||
|
; establish that they are in fact talking.
|
||||||
|
; 2. When talk detection AMI events are enabled, this value
|
||||||
|
; determines when talking has begun which results in
|
||||||
|
; an AMI event to fire. If this value is set too tight
|
||||||
|
; AMI events may be falsely triggered by variants in
|
||||||
|
; room noise.
|
||||||
|
; 3. The drop_silence option depends on this value to determine
|
||||||
|
; when the user's audio should be mixed into the bridge
|
||||||
|
; after periods of silence. If this value is too loose
|
||||||
|
; the beginning of a user's speech will get cut off as they
|
||||||
|
; transition from silence to talking.
|
||||||
|
;
|
||||||
|
; By default this value is 160 ms. Valid values are 1 through 2^31
|
||||||
|
|
||||||
|
;dsp_silence_threshold=2000 ; The time in milliseconds of sound falling within the what
|
||||||
|
; the dsp has established as baseline silence before a user
|
||||||
|
; is considered be silent. This value affects several
|
||||||
|
; operations and should not be changed unless the impact
|
||||||
|
; on call quality is fully understood.
|
||||||
|
;
|
||||||
|
; What this value affects internally:
|
||||||
|
;
|
||||||
|
; 1. When talk detection AMI events are enabled, this value
|
||||||
|
; determines when the user has stopped talking after a
|
||||||
|
; period of talking. If this value is set too low
|
||||||
|
; AMI events indicating the user has stopped talking
|
||||||
|
; may get falsely sent out when the user briefly pauses
|
||||||
|
; during mid sentence.
|
||||||
|
; 2. The drop_silence option depends on this value to
|
||||||
|
; determine when the user's audio should begin to be
|
||||||
|
; dropped from the conference bridge after the user
|
||||||
|
; stops talking. If this value is set too low the user's
|
||||||
|
; audio stream may sound choppy to the other participants.
|
||||||
|
; This is caused by the user transitioning constantly from
|
||||||
|
; silence to talking during mid sentence.
|
||||||
|
;
|
||||||
|
; The best way to approach this option is to set it slightly above
|
||||||
|
; the maximum amount of ms of silence a user may generate during
|
||||||
|
; natural speech.
|
||||||
|
;
|
||||||
|
; By default this value is 2500ms. Valid values are 1 through 2^31
|
||||||
|
|
||||||
|
;talk_detection_events=yes ; This option sets whether or not notifications of when a user
|
||||||
|
; begins and ends talking should be sent out as events over AMI.
|
||||||
|
; By default this option is off.
|
||||||
|
|
||||||
|
;denoise=yes ; Sets whether or not a denoise filter should be applied
|
||||||
|
; to the audio before mixing or not. Off by default. Requires
|
||||||
|
; codec_speex to be built and installed. Do not confuse this option
|
||||||
|
; with drop_silence. Denoise is useful if there is a lot of background
|
||||||
|
; noise for a user as it attempts to remove the noise while preserving
|
||||||
|
; the speech. This option does NOT remove silence from being mixed into
|
||||||
|
; the conference and does come at the cost of a slight performance hit.
|
||||||
|
|
||||||
|
;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
|
||||||
|
; dialplan function's default adaptive jitterbuffer. For a more fine tuned
|
||||||
|
; jitterbuffer, disable this option and use the JITTERBUFFER dialplan function
|
||||||
|
; on the user before entering the ConfBridge application.
|
||||||
|
|
||||||
|
;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
|
||||||
|
; name when entering the conference. After the name is
|
||||||
|
; recorded, it will be played as the user enters and exists
|
||||||
|
; the conference. This option is off by default.
|
||||||
|
;dtmf_passthrough=yes ; Sets whether or not DTMF should pass through the conference.
|
||||||
|
; This option is off by default.

; --- ConfBridge Bridge Profile Options ---
|
||||||
|
[default_bridge]
|
||||||
|
type=bridge
|
||||||
|
;max_members=50 ; This option limits the number of participants for a single
|
||||||
|
; conference to a specific number. By default conferences
|
||||||
|
; have no participant limit. After the limit is reached, the
|
||||||
|
; conference will be locked until someone leaves. Note however
|
||||||
|
; that an Admin user will always be alowed to join the conference
|
||||||
|
; regardless if this limit is reached or not.
|
||||||
|
|
||||||
|
;record_conference=yes ; Records the conference call starting when the first user
|
||||||
|
; enters the room, and ending when the last user exits the room.
|
||||||
|
; The default recorded filename is
|
||||||
|
; 'confbridge-<name of conference bridge>-<start time>.wav
|
||||||
|
; and the default format is 8khz slinear. This file will be
|
||||||
|
; located in the configured monitoring directory in asterisk.conf.
|
||||||
|
|
||||||
|
;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
|
||||||
|
; conferences may use the same bridge profile, this may cause issues
|
||||||
|
; depending on the configuration. It is recommended to only use this
|
||||||
|
; option dynamically with the CONFBRIDGE() dialplan function. This
|
||||||
|
; allows the record name to be specified and a unique name to be chosen.
|
||||||
|
; By default, the record_file is stored in Asterisk's spool/monitor directory
|
||||||
|
; with a unique filename starting with the 'confbridge' prefix.
|
||||||
|
|
||||||
|
;internal_sample_rate=auto ; Sets the internal native sample rate the
|
||||||
|
; conference is mixed at. This is set to automatically
|
||||||
|
; adjust the sample rate to the best quality by default.
|
||||||
|
; Other values can be anything from 8000-192000. If a
|
||||||
|
; sample rate is set that Asterisk does not support, the
|
||||||
|
; closest sample rate Asterisk does support to the one requested
|
||||||
|
; will be used.
|
||||||
|
|
||||||
|
;mixing_interval=40 ; Sets the internal mixing interval in milliseconds for the bridge. This
|
||||||
|
; number reflects how tight or loose the mixing will be for the conference.
|
||||||
|
; In order to improve performance a larger mixing interval such as 40ms may
|
||||||
|
; be chosen. Using a larger mixing interval comes at the cost of introducing
|
||||||
|
; larger amounts of delay into the bridge. Valid values here are 10, 20, 40,
|
||||||
|
; or 80. By default 20ms is used.
|
||||||
|
|
||||||
|
; All sounds in the conference are customizable using the bridge profile options below.
|
||||||
|
; Simply state the option followed by the filename or full path of the filename after
|
||||||
|
; the option. Example: sound_had_joined=conf-hasjoin This will play the conf-hasjoin
|
||||||
|
; sound file found in the sounds directory when announcing someone's name is joining the
|
||||||
|
; conference.
|
||||||
|
|
||||||
|
;sound_join ; The sound played to everyone when someone enters the conference.
|
||||||
|
;sound_leave ; The sound played to everyone when someone leaves the conference.
|
||||||
|
;sound_has_joined ; The sound played before announcing someone's name has
|
||||||
|
; joined the conference. This is used for user intros.
|
||||||
|
; Example "_____ has joined the conference"
|
||||||
|
;sound_has_left ; The sound played when announcing someone's name has
|
||||||
|
; left the conference. This is used for user intros.
|
||||||
|
; Example "_____ has left the conference"
|
||||||
|
;sound_kicked ; The sound played to a user who has been kicked from the conference.
|
||||||
|
;sound_muted ; The sound played when the mute option it toggled on.
|
||||||
|
;sound_unmuted ; The sound played when the mute option it toggled off.
|
||||||
|
;sound_only_person ; The sound played when the user is the only person in the conference.

||||||
|
;sound_only_one ; The sound played to a user when there is only one other
|
||||||
|
; person is in the conference.
|
||||||
|
;sound_there_are ; The sound played when announcing how many users there
|
||||||
|
; are in a conference.
|
||||||
|
;sound_other_in_party; ; This file is used in conjunction with 'sound_there_are"
|
||||||
|
; when announcing how many users there are in the conference.
|
||||||
|
; The sounds are stringed together like this.
|

|
|
||||||
|
; --- 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.
|
||||||
|
;
|
||||||
|
; 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
|
||||||
|
;
|
||||||
|
; playback(<name of audio file>&<name of audio file>)
|
||||||
|
; Playback will play back an audio file to a channel
|
||||||
|
; and then immediately return to the conference.
|
||||||
|
; This file can not be interupted by DTMF.
|
||||||
|
; Mutliple files can be chained together using the
|
||||||
|
; '&' character.
|
||||||
|
; playback_and_continue(<name of playback prompt>&<name of playback prompt>)
|
||||||
|
; playback_and_continue will
|
||||||
|
; play back a prompt while continuing to
|
||||||
|
; collect the dtmf sequence. This is useful
|
||||||
|
; when using a menu prompt that describes all
|
||||||
|
; the menu options. Note however that any DTMF
|
||||||
|
; during this action will terminate the prompts
|
||||||
|
; playback. Prompt files can be chained together
|
||||||
|
; using the '&' character as a delimiter.
|
||||||
|
; toggle_mute ; Toggle turning on and off mute. Mute will make the user silent
|
||||||
|
; to everyone else, but the user will still be able to listen in.
|
||||||
|
; continue to collect the dtmf sequence.
|
||||||
|
; no_op ; This action does nothing (No Operation). Its only real purpose exists for
|
||||||
|
; being able to reserve a sequence in the config as a menu exit sequence.
|
||||||
|
; decrease_listening_volume ; Decreases the channel's listening volume.
|
||||||
|
; increase_listening_volume ; Increases the channel's listening volume.
|
||||||
|
; reset_listening_volume ; Reset channel's listening volume to default level.
|
||||||
|
|
||||||
|
; decrease_talking_volume ; Decreases the channel's talking volume.
|
||||||
|
; increase_talking_volume ; Icreases the channel's talking volume.
|
||||||
|
; reset_talking_volume ; Reset channel's talking volume to default level.
|
||||||
|
;
|
||||||
|
; dialplan_exec(context,exten,priority) ; The dialplan_exec action allows a user
|
||||||
|
; to escape from the conference and execute
|
||||||
|
; commands in the dialplan. Once the dialplan
|
||||||
|
; exits the user will be put back into the
|
||||||
|
; conference. The possibilities are endless!
|
||||||
|
; leave_conference ; This action allows a user to exit the conference and continue
|
||||||
|
; execution in the dialplan.
|
||||||
|
;
|
||||||
|
; admin_kick_last ; This action allows an Admin to kick the last participant from the
|
||||||
|
; conference. This action will only work for admins which allows
|
||||||
|
; a single menu to be used for both users and admins.
|
||||||
|
;
|
||||||
|
; admin_toggle_conference_lock ; This action allows an Admin to toggle locking and
|
||||||
|
; unlocking the conference. Non admins can not use
|
||||||
|
; this action even if it is in their menu.
