Install G729 Codec on Asterisk Based SIP Server

Note : You might have to pay license fees to the Digium for using their G729 codecs.

Installation Steps ;

1. Find your CPU architecture with following command;

cat /proc/cpuinfo

2. Go to http://asterisk.hosting.lv/ and choose correct Asterisk version and CPU version.

3. Navigate the codec directory;

 cd /usr/lib/asterisk/modules

4. Download proper codec;

wget http://asterisk.hosting.lv/bin/codec_g729-ast14-gcc4-glibc-pentium.so

5. Change file permissions as 755

chmod 755 codec_g729-ast14-gcc4-glibc-pentium.so

6. Rename codec file name ;

mv codec_g729-ast14-gcc4-glibc-pentium.so codec_g729.so 

7. Add g729 codec support over the Asterisk SIP Settings on Freepbx Tools menu.
