HOW TO: Install the Free G729 Codec for Asterisk (ViciDial and GoAutodial)

 Installing the Free G729 Codec for Asterisk



This tutorial will let you install the G729 Codec on an Asterisk installation in under 5 minutes.


1. Login to your SSH and go Navigate to the codecs directory:

cd /usr/lib/asterisk/modules


2. Download the codec


A. Codecs are provided as binary .so files, you can find the archive at http://asterisk.hosting.lv/#bin
B. Take care of the following when picking up one of the files, they depend on your hardware/software:
Processor Architecture: Check the kernel type installed on your system (using “uname -a” )
Asterisk Version: As you can see there is codecs for Asterisk 1.2, 1.4 and also 1.6
The most used ones are the following:

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

http://asterisk.hosting.lv/bin/codec_g729-ast14-gcc4-glibc-x86_64-core2.so

C. Download Command:

[root@Machine modules]# wget http://asterisk.hosting.lv/bin/codec_g729-ast14-gcc4-glibc-pentium.so

NOTE: Notice that we are in the modules directory
3. Rename the codec file

mv codec_g729-ast14-gcc4-glibc-pentium4.so codec_g729.so


4. Install Codec:

Connect to Asterisk

asterisk -r

Then Type

Machine*CLI> module load codec_g729.so


5. Restart Asterisk:

/etc/init.d/asterisk restart


6. Check your work ( Be sure to double check and see if G729 was already installed)

Connect to Asterisk

asterisk -r
