G.723 and G.729 for Asterisk 11

You should compile Asterisk 11, so prepare your PC/server for it. Install development packages, get Asterisk 11 source, compile and install it.

Suppose you don’t want to install Asterisk 11 in your PC/server. You can configure and compile Asterisk 11, but don’t need to install it. After that you can continue compile the codec.

Now, assumed you have compiled Asterisk 11 and install it in /opt/asterisk on your PC/server.

Follow below steps to compile codec g723 and g729:

wget -c http://asterisk.hosting.lv/src/asterisk-g72x-1.1.tar.bz2
tar -jxf asterisk-g72x-1.1.tar.bz2
cd asterisk-g72x-1.1/
./configure --with-asterisk-includes=/opt/asterisk/include --with-asterisk100 --enable-pentium4 --with-itu
make
cd .libs
ls -l *.so

Copy codec_g723.so and codec_g729.so to your Asterisk 11 modules directory.

Should you use not a Pentium 4 compatible just replace –enable-pentium4 with your PC/server architecture. Get options by running ./configure –help in the codec source directory asterisk-g72x-1.1.

These are complete steps when you don’t want to install Asterisk 11 but need to compile the codec.

apt-get install build-essential
wget -c http://downloads.asterisk.org/pub/telephony/asterisk/asterisk-11-current.tar.gz
tar -zxf asterisk-11-current.tar.gz
cd asterisk-11.4.0
./configure --disable-xmldoc
make
cd ../
wget -c http://asterisk.hosting.lv/src/asterisk-g72x-1.1.tar.bz2
tar -jxf asterisk-g72x-1.1.tar.bz2
cd asterisk-g72x-1.1/
./configure --with-asterisk-includes=../asterisk-11.4.0/include --with-asterisk100 --enable-pentium4 --with-itu
make
cd .libs
ls -l *.so

G729 for ARM Processor

apt-get install build-essential checkinstall cvs subversion git-core mercurial

cd /usr/src
wget http://download-mirror.savannah.gnu.org/releases/linphone/plugins/sources/bcg729-1.0.0.tar.gz
tar xzf bcg729-1.0.0.tar.gz
cd bcg729-1.0.0/
./configure
make && make install
ldconfig

cd /usr/src
hg clone http://bitbucket.org/arkadi/asterisk-g72x
cd asterisk-g72x/
vi configure.ac

在 case "${host}" in 這行下方

  armv7l-unknown-linux-gnueabihf*)
    cflags="-O3 -funroll-loops -marm -mtune=cortex-a7 -Wall"
    march="armv7-a"
    ;;

NOTE:

以上修改適合 Raspberry Pi 與 Cubieboard v1

開始編譯

./autogen.sh
./configure --with-asterisk-includes=/usr/src/asterisk-12.4.0/include/ --with-bcg729
make
make install
ldconfig 

NOTE:

* 必須先下載 Asterisk 安裝原始檔

*  執行 autogen.sh 後才會有 configure 指令，如果遇到錯誤，必須先安裝 autoconf , automake 套件。

* --with-asterisk-includes Asterisk 原始安裝檔目錄內的 include 目錄

* --with-bcg729 會自動偵測 bcg729 函式庫，如果想指定特定目錄，直接改成 --with-bcg729=/path/to/lib
