CPU Type

First of all you need to know your CPU type. Do:

cat /proc/cpuinfo

It will show CPU info and you will see a lot of info. Most crucial is:

model name      : Intel(R) Core(TM)2 Duo CPU     E4500  @ 2.20GHz

NOTE: this will vary on different servers, but from this line you can see what kind of CPU is on this particular machine.

Here as example we see that we have Intel(R) Core(TM)2 Duo CPU.

x86_64?

Then we need to know if our server is x86_64. For that we do:

uname -a

And we see that it is:

Linux xxxx #1 SMP Fri Nov 30 00:45:55 EST 2007 x86_64 x86_64 x86_64 GNU/Linux

Codec installation

Now go to: http://kvin.lv/pub/Linux/Asterisk/ and from the section: Asterisk 1.4 (if you use Asterisk 1.4) select the most appropriate codec.

For our example CPU we will choose:

codec_g723-ast14-gcc4-glibc-x86_64-pentium4.so
codec_g729-ast14-gcc4-glibc-x86_64-pentium4.so

Now download these files to your server:

cd /usr/src/
wget http://asterisk.hosting.lv/bin/codec_g723-ast14-gcc4-glibc-x86_64-pentium4.so
wget http://asterisk.hosting.lv/bin/codec_g729-ast14-gcc4-glibc-x86_64-pentium4.so

Rename them to:

mv /usr/src/codec_g723-ast14-gcc4-glibc-x86_64-pentium4.so /usr/src/codec_g723.so
mv /usr/src/codec_g729-ast14-gcc4-glibc-x86_64-pentium4.so /usr/src/codec_g729.so

CHMOD both of them to 777:

chmod 777 codec_g72*.so

And copy to Asterisk modules:

cp codec_g72*.so /usr/lib/asterisk/modules


Testing

Restart Asterisk and execute in CLI:

show translation

It should show something like this:

CLI> show translation
        Translation times between formats (in milliseconds) for one second of data
         Source Format (Rows) Destination Format (Columns)
