From this information we can see that it is a Pentium III processor and it is using sse.  These are the 2 bits of required information we need.  If you don’t see sse in your flags settings then the file you need must contain the words no-sse
From this information we can see that it is a Pentium D processor.  These are the 2 bits of required information we need.  If you don’t see sse in your flags settings then the file you need must contain the words no-sse


Now go to http://asterisk.hosting.lv/ and select the appropriate Asterisk version.
Now go to http://asterisk.hosting.lv/ and select the appropriate Asterisk version.
The files are named as codec_g72x-???-pentiumx.so
So from the information above to obtain the G729 codec we need to get the file codec_g729-gcc-pentium3.so and for the G723 codec we need to get the file g723-gcc-pentium3.so
The gcc represents the way the module was compiled.  This is your most likely choice.  To view the different type of compiled version look at this file http://kvin.lv/pub/Linux/Asterisk/README
Now that we know what file we need you can now download the appropriate file.


Change folders to /usr/lib/asterisk/modules

If Asterisk does not start then you may need to try icc files instead of gcc.
If Asterisk does not start then you will need to use a different version of the codec files.

G729 and G723 Codec Install
Before downloading the codec module you need to verify what your processor type is, as to get a compatible compiled codec.

From the Linux command type in:

cat /proc/cpuinfo

Look specifically at the model name and the flags. The following is an example of the process that I am using.

processor       : 0
vendor_id       : GenuineIntel
cpu family      : 15
model           : 6
model name      : Intel(R) Pentium(R) D CPU 3.00GHz
stepping        : 5
microcode       : 0x7
cpu MHz         : 3000.249
cache size      : 2048 KB
physical id     : 0
siblings        : 2
core id         : 0
cpu cores       : 2
apicid          : 0
initial apicid  : 0
fpu             : yes
fpu_exception   : yes
cpuid level     : 6
wp              : yes
flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe syscall nx lm constant_tsc pebs bts nopl pni dtes64 monitor ds_cpl est cid cx16 xtpr pdcm lahf_lm
bogomips        : 6000.49
clflush size    : 64
cache_alignment : 128
address sizes   : 36 bits physical, 48 bits virtual
power management:

From this information we can see that it is a Pentium D processor. These are the 2 bits of required information we need. If you don’t see sse in your flags settings then the file you need must contain the words no-sse

Now go to http://asterisk.hosting.lv/ and select the appropriate Asterisk version.

Change folders to /usr/lib/asterisk/modules

cd /usr/lib/asterisk/modules

Download the required file(s)

For the G729 codec with a Pentium 4 sse chip:

wget http://asterisk.hosting.lv/bin/codec_g729-ast120-gcc4-glibc-x86_64-pentium4.so

For the G723 codec with a Pentium 4 sse chip:

wget http://asterisk.hosting.lv/bin/codec_g723-ast120-gcc4-glibc-x86_64-pentium4.so

Restart asterisk and you are done.

If Asterisk does not start then you will need to use a different version of the codec files.
