G729

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	: 6
model		: 8
model name	: Pentium III (Coppermine)
stepping	: 3
cpu MHz	        : 648.110
cache size	: 256 KB
fdiv_bug	: no
hlt_bug	        : no
f00f_bug	: no
coma_bug	: no
fpu		: yes
fpu_exception	: yes
cpuid level	: 2
wp		: yes
flags		: fpu vme de pse tsc msr pae mce cx8 mtrr pge mca cmov pat pse36 mmx fxsr sse
bogomips	: 1297.41

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

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

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-ast18-icc-glibc-pentium4.so

For the G723 codec with a Pentium 4 sse chip:

wget http://asterisk.hosting.lv/bin/codec_g723-ast18-icc-glibc-pentium4.so

Restart asterisk and you are done.

If Asterisk does not start then you may need to try icc files instead of gcc.
