Step 1
------
Download the code from Intel

cd /tmp
wget ftp://download.intel.com/software/products/ipp/downloads/samples/l_ipp-sample-speech-coding_p_4.1.008.tgz
wget ftp://download.intel.com/software/products/ipp/downloads/l_ipp_ia32_itanium_p_4_1.tar

Step 2
------

Install IPP libraries.

mkdir /tmp/ipp-tmp
cd /tmp/ipp-tmp
tar xf /tmp/l_ipp_ia32_itanium_p_4_1.tar

Follow Intel's instructions to install IPP.  If using Debian, the Intel
installed will stop half way, leaving a .rpm file sitting in a subdirectory
of /tmp.  You can install the .rpm file using `alien' and then proceed.

Once you've installed IPP and agreed to the license terms, you may need to
copy the libraries from one PC to another (eg, from your development machine
to a production server).  You just need to copy the contents of the following
directory:

/opt/intel/ipp41/ia32_itanium/sharedlib/

without re-running the install process.

Step 3
------

Install IPP sample code

cd /usr/local/src
tar xzf /tmp/l_ipp-sample-speech-coding_p_4.1.008.tgz

Step 4
------

Apply my patch

cd intel1/ipp_sample/speech-coding/G729-float/
patch -p2 < /tmp/g729.diff

Step 5
------

Build

./build.sh

Step 6
------

Deploy

cp bin/codec_g729.so /usr/lib/asterisk/modules   (this location depends
							on your system)

Insert the following into /etc/init.d/asterisk:

export LD_LIBRARY_PATH=/opt/intel/ipp41/ia32_itanium/sharedlib:/opt/intel/ipp41/ia32_itanium/sharedlib/linux32:$LD_LIBRARY_PATH

You may need to insert the following into your sip.conf:

allow=g729

Now restart Asterisk

/etc/init.d/asterisk restart

Step 7
------

Verify install

At the shell prompt:
# asterisk -r

At the Asterisk prompt:
>show translation

If the G.729 column has -'s instead of numbers, then the codec is not
working properly.
