                    This option drops what Asterisk detects as silence from
                    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.

                        operations and should not be changed unless the impact on call
                        quality is fully understood.

                        <para>What this value affects internally:
                        </para>
                        <para>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.
                        </para>
                        <para>2. The <replaceable>drop_silence</replaceable> 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.
                        </para>
                        <para>The best way to approach this option is to set it slightly
                        above the maximum amount of milliseconds of silence a user may
                        generate during natural speech.

                        this level is considered silence.  This value affects several
                        operations and should not be changed unless the impact on call

                        </para>
                        <para>1. Audio is only mixed out of a user's incoming audio
                        stream if talking is detected.  If this value is set too
                        high the user will hear himself talking.
                        </para>
                        <para>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 low
                        AMI events may be falsely triggered by variants in
                        room noise.
                        </para>
                        <para>3. The <replaceable>drop_silence</replaceable> 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 high the user's speech will get discarded as they will
                        be considered silent.

                        Enabling this option places a jitterbuffer on the user's audio stream

                        directly after the check the bridge can be destroyed before the new caller
                        enters (creating a new bridge), for example, and the "first member" actions
                        could thus be missed.

                        Sets the interval in milliseconds that a combined REMB frame will be sent
                        to video sources. This is done by taking all REMB frames that have been
                        received since the last REMB frame was sent, making a combined value,
                        and sending it to the source. A REMB frame contains receiver estimated
                        maximum bitrate information. By creating a combined REMB frame the
                        sender of video can be influenced on the bitrate they choose, allowing
                        better quality for all receivers.

                    <para>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.</para>
                    <para>Below is a list of menu actions that can be assigned to a DTMF sequence.</para>
                    <note><para>
                        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: The mute setting is
                        toggled when <literal>#1</literal> is pressed.</para>
                        <para><literal>\#1=toggle_mute</literal></para>

                    <note><para>
                    A single DTMF sequence can have multiple actions associated with it. This is
                    accomplished by stringing the actions together and using a <literal>,</literal> as the
                    delimiter.  Example:  Both listening and talking volume is reset when <literal>5</literal> is
                    pressed.  <literal>5=reset_talking_volume, reset_listening_volume</literal></para></note>
