Enter  which  codecs are to be  supported.  For  some  protocols (e.g.  SIP),  the  G711U  and  G711A 
protocols are always supported by default.  
 
Select which complex codec is to be supported. Due to memory limitations, it is not possible to 
select more than one complex codec. 
 
Select the packetization period to be used for each selected CODEC.  
 
Select whether Silence Suppression is to be supported for each CODEC. 
 
The  Jitter  Buffer  settings  apply  to  all  active  CODEC  decoders.  You  may  choose  between  an 
adaptive jitter  buffer  or  a  fixed jitter  buffer.  For  an  adaptive  jitter  buffer,  choose  the  maximum 
allowable playout delay (in milliseconds). For a fixed jitter buffer, choose the fixed playout delay 
(in milliseconds). 
 
Finally, select whether or not a decoder should automatically switch from an adaptive jitter buffer 
to  a  fixed  jitter  buffer  upon  fax/modem  tone  detection.  Adaptive  jitter  buffers  are  sometimes 
detrimental  to  fax  transmission  over  G711  CODECs  if  they  have  to  adapt  too  rapidly  or  too 
extensively  due  to  inconsistent  and  widespread  packet  delays.  In  these  adverse  network 
conditions,  a  fixed  jitter  buffer  provides  superior  performance  when  handling  incoming  fax 
transmissions over G711 CODECs.
