Silence Suppression Controls the silence suppression/VAD feature of the audio codec G.723
and G.729. If set to "Yes", when silence is detected, a small quantity of
VAD packets (instead of audio packets) will be sent during the period of
no talking. If set to "No", this feature is disabled. The default setting is
"No".
Voice Frames Per TX Configures the number of voice frames transmitted per packet. When
configuring this, it should be noted that the "ptime" value for the SDP will
change with different configurations here. This value is related to the
codec used and the actual frames transmitted during the in payload call.
For end users, it is recommended to use the default setting, as incorrect
settings may influence the audio quality.
Jitter Buffer Type Selects either Fixed or Adaptive based on network conditions. The
default setting is "Adaptive".
Jitter Buffer Length Selects Low, Medium, or High based on network conditions. The default
setting is "Medium".
