Set  the  jitter  buffer  adaptation 
mode: 
 
non-immediate—gradual; 
immediately—instant. 
Set  the  buffer  adaptation  mode. 
Defines  the  method  of  packet 
deletion  during  buffer  adaptation  to 
the lower limit. 
 
soft—the  device  uses  an  intelligent 
selection  pattern  to  delete  the 
packets,  which  exceed  the 
threshold; 
hard—the  packets,  which  delay 
exceeds  the  threshold,  are 
deleted immediately. 
jitter  deletion 
threshold 
Set  a  threshold  for  immediate 
deletion of  a  packet,  in  milliseconds. 
When  buffer  size  grows  and  packets 
delay  exceeds  this  threshold,  the 
packets are deleted immediately. 
Specify an initial value of an adaptive 
jitter buffer, in milliseconds
