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      : 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

fpu             : yes
fpu_exception   : yes

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.
