[asterisk-users] Question on Codecs

[Nhadie]

Hi,

I'm testing using the free g723 codecs and i have successfully installed 
them.
          g723
    g723     -
     gsm     9
    ulaw     9
    alaw     9
    g726     9
   adpcm     9
    slin     8
   lpc10    10
    g729    10
   speex     -
    ilbc    10


i also set my pap2's to use G723. I'm sending the call to an AS5400 with 
multiple E1's on it. problem i noticed is that my CPU went up to 65% 
usage. From 4% when i was using ulaw. does asterisk still do codec 
translation even if the g723 codec is installed on it?

this is the result from top command:
                                           %CPU  %MEM
16829 asterisk  15   0 42500  22m 5520 S   65   2.6  91:21.93 asterisk

i have 55 simultaneous users testing it. as far as my understanding, 
when g723 is installed on the asterisk there should be no codec 
translation done on the server thus not utilizing that much CPU.
am i understanding it correctly? thanks in advanced

regards,
Ron
