為什麼我要安裝比較老的asterisk-1.8.10.1，而不是更加新的穩定版本？

因為我還要加AMR-NB audio codec。

CentOS使用者準備：useradd asterisk

1.下載CentOS 5.8

國內高速下載

http://mirrors.163.com/centos/5.8/isos/i386/CentOS-5.8-i386-bin-DVD-1of2.isohttp://mirrors.163.com/centos/5.8/isos/i386/CentOS-5.8-i386-bin-DVD-2of2.iso

2.Windows XP上用Vmware Player安裝CentOS虛擬機器

3.Download Asterisk , DAHDI, libpri, libSRTP. First got to /usr/src/ directorysu -cd /usr/src

4.wget http://downloads.asterisk.org/pub/telephony/asterisk/releases/asterisk-1.8.10.1.tar.gz

可能是因為我的CentOS比較新，所以要高於2.4版本的dahdi

5.wget http://downloads.Asterisk.org/pub/telephony/dahdi-linux-complete/releases/dahdi-linux-complete-2.5.0.2+2.5.0.2.tar.gz

6.wget http://downloads.Asterisk.org/pub/telephony/libpri/releases/libpri-1.4.11.4.tar.gz

7.wget http://sourceforge.net/projects/srtp/files/srtp/1.4.4/srtp-1.4.4.tgz/download

8.yum -y install kernel-devel gcc make gcc-c++ libxml2-devel pkgconfig zlib-devel yum -y install openssl-devel ncurses-devel autoconf automake libtool zip unzipExtract Asterisk & DAHDi & libpri & libsrtp9.tar -xzvf asterisk-1.8.10.1.tar.gz10.tar -xzvf  dahdi-linux-complete-2.5.0.2+2.5.0.2.tar.gz11.tar -xzvf libpri-1.4.11.4.tar.gz12.tar -xzvf srtp-1.4.4.tgzCompile srtp, dahdi , libpri and Asterisk (the compilations order is important)13. cd /usr/src/srtp14.

Time to compile dahdi23. cd ../dahdi-linux-complete-2.5.0.2+2.5.0.2

24. make all

出錯處理：You do not appear to have the sources for the 2.6.18-308.el5 kernel installed.

uname -r

2.6.18-308.el5

cd /lib/modules/

看到下面有 2.6.18-308.11.1.el5  2.6.18-308.el5

cd /lib/modules/2.6.18-308.el5

重新建立build link

rm build

 ln -s  ../../../usr/src/kernels/2.6.18-308.11.1.el5-i686/ build

解決辦法2：

#  yum -y install kernel-devel-`uname -r`

25. make install26. make config

螢幕提示：

/sbin/chkconfig --add dahdiDAHDI has been configured.List of detected DAHDI devices:pci:0000:03:0c.0     wcfxo-       1057:5608 Wildcard X100Prun 'dahdi_genconf modules' to load support for onlythe DAHDI hardware installed in this system.  Bydefault support for all DAHDI hardware is loaded atDAHDI start.

Time to compile libpri

27. cd ../libpri-1.4.11.4 

(now we are in /usr/src/libpri-1.4.11.4)

28. make29. make install

30.Time to copmpile Asterisk

注：yum install ncurses-devel（make menuconfig要這個包）

cd asterisk-1.8.10.1

contrib/scripts/install_prereq install

注意：如要mp3，需要執行下面操作yum install subversion contrib/scripts/get_mp3_source.sh

注意：如要ilbc codec，需要執行下面操作contrib/scripts/get_ilbc_source.sh

cd codec/ilbc/

看到裡面只有幾個檔案

extract-cfile.awk rfc3951.txt

內容到extract-cfile.awk

awk -f extract-cfile.awk rfc3951.txt

這將在這個目錄下面產生幾十個檔案。

參考：

31.  cd ../../

./configure --with-bluetooth

32. make menuconfig    (add-on 選擇chan_mobile, format_mp3, res_config_mysql,  EXTRAS-SOUNDS-EN-GSM )Running this command will be show the following menu :

Add AMR codec supportBefore start to configure Asterisk, we would like to add one more tool, we reallly need to use ARM-NB codec (AdaptiveMultirate-Codec Ultra Narrow Band) in conjunction with PrivateGSM Enterprise on a mobile phone to get the best voice qualityusing mobile internet connections.Please consider that G.729 codec does not work for mobile network connections in a reliable way, for example it does not workover GPRS or in degraded network conditions (that on a mobile, means often).Be sure to read notes on licensing at the end of this howto in order to properly license the AMR codec.
