I lay out instructions for assembling and installing the G729 and G723 codecs for Asterisk from source code, test assembly was performed on a thin HP client and on a 64-bit server.
Codec. G729 One of the best codecs in terms of quality to audio stream compression. It is used in most cases if there are restrictions on the bandwidth of traffic. For its use in industrial use, a license is required. The License Agreement can be read on page of the license agreement. The G729 uses a compression rate of 8 Kbps, which is 8 times less than the standard alaw G711 codec.
To calculate the bandwidth, you can use calculator.
Dano:
Asterisk 1.8 is installed according to the instructions: Install Asterisk 1.8 in Debian Squeeze or Ubuntu Linux, build from VOIP Asterisk source
or:
Asterisk 1.8 is installed according to the instructions: Installing Asterisk PBX 11 on Debian or Ubuntu Linux
Go to the folder where we have the source code installed Asterisk, dahdi, libpri, If there is no folder, we will create it by completing the command:
mkdir -p /usr/src/asterisk-src/ && cd /usr/src/asterisk-src/
Download the source codecs on the official website team:
wget http://asterisk.hosting.lv/src/asterisk-g72x-1.1.tar.bz2
If the official site does not have this archive, or the site is not available, then you can download this archive from my website by following the command:
wget http://softnastroy.com/downloads/asterisk/asterisk-g72x-1.1.tar.bz2
Unpack the downloaded archive, go to the unpacked folder and start configuring the codec by executing the commands:
tar xvf asterisk-g72x-1.1.tar.bz2 cd asterisk-g72x-1.1 ./configure --with-ipp=ipp/
Modifying the file. build-itu.sh
vi build-itu.sh
For Asterisk 1.8:
was:
# Asterisk 1.8 inc=/home/arkadi/opt/asterisk-1.8.0/include def=-DG72X_ASTERISK=18
became:
inc=/usr/src/asterisk-src/asterisk-1.8.28.2/include def=-DG72X_ASTERISK=18
For Asterisk 11:
was:
# Asterisk 10.0 inc=/home/arkadi/opt/asterisk-10.0/include def=-DG72X_ASTERISK=10
became:
# Asterisk 11.0 inc=/usr/src/asterisk-src/asterisk-11.20.0/include/ def=-DG72X_ASTERISK=110
By the way, to install on Asterisk versions not 1.8, but for example Asterisk 1.4, Asterisk 1.6 or Asterisk 10, you need to comment on the unnecessary and decomment the desired version of Asterisk, as well as correct the path of finding the source installed Asterisk in the file. build-itu.sh
Run the edited file with the command:
sh build-itu.sh
After assembling the codecs, copy the G723 and G729 codecs with the command:
cp codec_g72*.so /usr/lib/asterisk/modules/
Reboot Asterisk with the command:
/etc/init.d/asterisk restart
Check if the codecs are connected using the console asterisk launcher rasterisk either asterisk -r and running a command in the console. core show translation:

voip*CLI>We see our connected codecs on the list. G729 and G723.
To connect codecs to Asterisk, you need to enter data into sip.conf
was:
disallow=all ; First disallow all codecs allow=alaw ; Allow codecs in order of preference
became:
disallow=all ; First disallow all codecs allow=g729 allow=alaw ; Allow codecs in order of preference
If you each client is prescribed how to use a codec, then he needs to prescribe the same and codec. g729 file-based sip.conf
In order to see what codecs are used at a given time, you need to execute the command in the Asterisk console. sip show channels And watch the column. Format:
rasterisk voip*CLI> sip show channels Peer User/ANR Call ID Format Hold Last Message Expiry 192.168.XXX.XXX XXXXXXXXXX XXXXXXXXXXXXX 0x100 (g729) No Rx: ACK 192.168.XXX.XXX XXXXXXXXXX XXXXXXXXXXXXX 0x8 (alaw) No Rx: ACK 192.168.XXX.XXX XXX XXXXXXXXXXXXX 0x8 (alaw) No Init: INVITE 192.168.XXX.XXX XXX XXXXXXXXXXXXX 0x100 (g729) No Rx: ACK 192.168.XXX.XXX XXX XXXXXXXXXXXXX 0x8 (alaw) No Init: INVITE 192.168.XXX.XXX XXX XXXXXXXXXXXXX 0x100 (g729) No Tx: ACK 6 active SIP dialogs
The task is accomplished, the G723 and G729 codecs are assembled and installed, and the G729 codec is connected to Asterisk.
