Subject: [asterisk-users] Explain "core show translation"

 

Hi,

I've read in http://www.voip-info.org/wiki/view/Asterisk+codecs but I still
have questions about "core show translation".

How are values replied by "core show translation" computed in the the first
place ?
I've got 2 machines using a 3GHz Intel CPU : 1 is a Xeon, 1 is a Pentium 4
(gathered with cat /proc/cpuinfo)

The Xeon machine is showing, for instance:
                   gsm
     ulaw     -  1601 

The other shows:
                   gsm
     ulaw     -  2 

Why are these values so different ?
Is it correct to say "if "core show translation" is showing a 4 digits value
in its matrix, then the translation path between corresponding codecs is
unusable.

Regards

 

Perhaps the Xeon machine needs some optimization since a "ulaw-to-gsm"
translation take 1.6 seconds for 1 second of data as opposed to .002 seconds
on the P4 machine.
