dotasterisk安装g729和g723编码都很简单，下面以安装g729编码为例进行说明。安装g723编码类似。
1）请先ssh登录到 dotasterisk 系统，使用 【cat /proc/cpuinfo 】 查看机器的cpu型号和指令集，查看dotasterisk的asterisk版本，以及dotasterisk操作系统的架构，详见下面的红色标记，如下:
[root@dotasterisk:~]#cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 158
model name : Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz
stepping : 9
cpu MHz : 3000.092
cache size : 6144 KB
fpu : yes
fpu_exception : yes
cpuid level : 22
wp : yes

[root@dotasterisk:~]#asterisk -V
Asterisk 1.8.32.3
[root@dotasterisk:~]#
[root@dotasterisk:~]#da-version
DotAsterisk 2.0 (built: Oct 24 2017 09:53:17)
Copyright (c) 2010-2015 DotAsterisk Technology Co. Ltd
Official website: http://www.enjoycti.com/
[root@dotasterisk:~]#
[root@dotasterisk:~]#uname -a
Linux dotasterisk 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
[root@dotasterisk:~]#
2）请到 http://asterisk.hosting.lv/ 下载 dotasterisk 对应的 asterisk版本的 g729编码模块。
由于DotAsterisk 2.0 呼叫中心系统是 采用 asterisk1.8 ，基于centos6.5 的 64位 系统，所以 应该选择 【gcc4-glibc-x86_64 】相关编译的库文件。另外，从上面的cpu信息可以看出，我的机器是采用 酷睿架构，而且支持 sse4指令集，所以我们选择下载如下这个库：
codec_g729-ast18-gcc4-glibc-x86_64-core2-sse4.so
也可以从 点星PBX官方论坛 下载该模块库，下载链接如下：
http://www.dotasterisk.cn/downlo ... 86_64-core2-sse4.so
3）请将下载的库 采用ssh客户端工具（secureCRT、WinSCP）等传到 dotasterisk 系统里面的 【/opt/asterisk/lib/asterisk/modules/】目录，并给与755权限，正确上传模块成功后，详见如下：
[root@dotasterisk:~]#cd /opt/asterisk/lib/asterisk/modules/
[root@dotasterisk:/opt/asterisk/lib/asterisk/modules]#
[root@dotasterisk:/opt/asterisk/lib/asterisk/modules]#ls codec_g729-ast18-gcc4-glibc-x86_64-core2-sse4.so
codec_g729-ast18-gcc4-glibc-x86_64-core2-sse4.so
[root@dotasterisk:/opt/asterisk/lib/asterisk/modules]#
[root@dotasterisk:/opt/asterisk/lib/asterisk/modules]#chmod 755 codec_g729-ast18-gcc4-glibc-x86_64-core2-sse4.so ##【很重要】千万别忘记修改权限
[root@dotasterisk:/opt/asterisk/lib/asterisk/modules]#
4）进入asterisk控制台，使用【module load】命令加载该模块
[root@dotasterisk:/opt/asterisk/lib/asterisk/modules]#asterisk -r

g722 - 2000 1001 1001 2999 1999 1000 1999 2000 - 4999 2000
5）在dotasterisk的sip和iax配置文件中启用g729编码。采用如下命令:
echo -e "disallow=all\nallow=g729" >> /opt/app/ast/asterisk/sip_general_custom.conf
echo -e "disallow=all\nallow=g729" >> /opt/app/ast/asterisk/iax_general_custom.conf
6）重启asterisk，使配置修改生效。
[root@laravel55:/opt/app/ast/asterisk]#/etc/init.d/asterisk restart
Stopping safe_asterisk: [ OK ]
Shutting down asterisk: [ OK ]
Starting asterisk: [ OK ]
[root@laravel55:/opt/app/ast/asterisk]#
