Object

column r/w Integer32

This object contains the user configured preference for
each codec. Lower the number, higher the preference of the
codec.
              
If the call agent does not specify the preferred codec list
in CRCX(CreateConnection) request then the codec used 
will be the one of highest preference, as configured 
in this object.
              
The default preference based on the codec type is 
   G729ab will have preference 1
   G729a  will have preference 2
   G726 at rate 16 kbps will have preference 3
   G726 at rate 24 kbps will have preference 4 
   G726 at rate 32 kbps will have preference 5 
   G726 at rate 40 kbps will have preference 6 
   G.711u will have preference 7 for T1 and will have
                       preference 8 for E1 
   G.711a will have preference 7 for E1 card and will
                   have preference 8 for T1 
   clearChannel will have preference 9 
   G723H  will have preference 10
   G723AH will have preference 11
   G723L  will have preference 12
   G723AL will have preference 13
   Lossless will have preference 14
              
If the preference of a codec is zero then that codec
will not be used.
