Description
This value is used when the system flag
FORCE_SYSTEM_BROADCAST_VOLUME is set to YES.
Determines the default audio level with which the participants
connects and sends audio to the conference.
The volume scale is from 1 to 10, where 1 is the weakest and 10 is
the strongest. The default connection value is 5.
Each unit change represents an increase or decrease of 3 dB
(decibel).
Range: 1-10
Default: 5
This value is used when the system flag
FORCE_SYSTEM_LISTENING_VOLUME is set to YES.
Determines the default audio level with which the participants
connects and receives audio from the conference.
The volume scale is from 1 to 10, where 1 is the weakest and 10 is
the strongest. The default value is 5. Each unit change represents
an increase or decrease of 3 dB (decibel).
Range: 1-10
Default: 5
This flag regulates the Traffic Control buffer or maxburst size as a
percentage of the participant line rate.
Range: 1-30.
This flag limits the latency (in milliseconds) or the number of bytes
that can be present in a queue.
Range: 1-1000 (in milliseconds).
The number of seconds the server will wait for a TCP client to
answer a call before closing the connection.
Default = 5 (seconds)
Used for the MTU (Maximum transmitting Unit - the size of
transmitted packets) dynamic calculation:
New MTU = video bit rate / TRAFFIC_SHAPING_MTU_FACTOR
where the new MTU value is guaranteed to be a minimum of 410,
and a maximum of 1460 (MAX_MTU). The purpose of this
calculation is to match video rate in outgoing video to call rate, yet
force lower encoder bit rates to avoid overflow.
This flag is applicable only when traffic shaping is enabled (see
ENABLE_RTP_TRAFFIC_SHAPING).
Range: 0-5000, where 0 signifies no change in MTU
Default: 800
