为什么我要安装比较老的asterisk-1.8.10.1,而不是更加新的稳定版本?
因为我还要加AMR-NB audio codec。
参考文档:http://www.venturevoip.com/How-to-asterisk.1.8_SRTPTLS_snom300_pgsm.pdf
CentOS用户准备:
useradd asterisk
1.下载CentOS 5.8
国内高速下载
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安装CentOS虚拟机
3.Download Asterisk , DAHDI, libpri, libSRTP. First got to /usr/src/ directory
su -
cd /usr/src
4.wget http://downloads.asterisk.org/pub/telephony/asterisk/releases/asterisk-1.8.10.1.tar.gz
可能是因为我的CentOS比较新,所以要高于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.gz6.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 unzip
Extract Asterisk & DAHDi & libpri & libsrtp
9.
tar -xzvf asterisk-1.8.10.1.tar.gz
10.
tar -xzvf dahdi-linux-complete-2.5.0.2+2.5.0.2.tar.gz
11.
tar -xzvf libpri-1.4.11.4.tar.gz
12.
tar -xzvf srtp-1.4.4.tgz
Compile srtp, dahdi , libpri and Asterisk (the compilations order is important)
13. cd /usr/src/srtp
14.
CFLAGS="-Wall -O4 -fexpensive-optimizations -funroll-loops -fPIC"
./configure --prefix=/usr15. make
16.
vi /root/.bash_profile
修改PATH=$PATH:$HOME/bin
为 PATH=$PATH:$HOME/bin:.
su -
cd /usr/src/srtp
-否则make runtest报错: rtpw_test.sh: line 27: rtpw: command not found
make runtest
17. make install
18. make clean
--------------------------------------------------
23. cd ../dahdi-linux-complete-2.5.0.2+2.5.0.2
24. make all
出错处理: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
重新创建build link
rm build
ln -s ../../../usr/src/kernels/2.6.18-308.11.1.el5-i686/ build
解决办法2:
# yum -y install kernel-devel-`uname -r`
26. make config
屏幕提示:
/sbin/chkconfig --add dahdi
DAHDI has been configured.
List of detected DAHDI devices:
pci:0000:03:0c.0 wcfxo- 1057:5608 Wildcard X100P
run 'dahdi_genconf modules' to load support for only
the DAHDI hardware installed in this system. By
default support for all DAHDI hardware is loaded at
DAHDI 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要这个包)
cd asterisk-1.8.10.1
contrib/scripts/install_prereq install
注意:如要mp3,需要执行下面操作
yum install subversion
contrib/scripts/get_mp3_source.sh
注意:如要ilbc codec,需要执行下面操作
contrib/scripts/get_ilbc_source.sh
cd codec/ilbc/
看到里面只有几个文件
extract-cfile.awk rfc3951.txt
拷贝 http://ilbcfreeware.org/documentation/extract-cfile.txt
内容到extract-cfile.awk
awk -f extract-cfile.awk rfc3951.txt
这将在这个目录下面产生几十个文件。

31. cd ../../
./configure --with-bluetooth
32. make menuconfig (add-on 选择chan_mobile, format_mp3, res_config_mysql, EXTRAS-SOUNDS-EN-GSM )
Running this command will be show the following menu :
33. make
34. make install
35. make config36. make samples (this command will generate sample configuration files for Asterisk, under /etc/Asterisk/ folder)
37. service dahdi restart
38. service asterisk restart
netstat -na|grep 506
udp 0 0 0.0.0.0:5060 0.0.0.0:*
Add AMR codec support
Before 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 quality
using 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 work
over 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.
Stop Asterisk
39. service asterisk stopWe go back to /usr/src/ folder,download the Asterisk-amr patch.
40. cd /usr/src/
Download Asterisk-amr patch
41. wget http://sourceforge.net/projects/asterisk-amr/files/1.8.0-rc2_asterisk_amr_patch.diff/download
Apply the patch for AMR codec
42. cd asterisk-1.8.10.1/ && patch -p2 < ../1.8.0-rc2_asterisk_amr_patch.diff
Go to asterisk-1.8.0-rc2/codecs/amr/ folder
43. cd ../asterisk-1.8.10.1/codecs/amr/
Download AMR codec from 3GPP site
44. wget http://www.3gpp.org/ftp/Specs/archive/26_series/26.104/26104-700.zip
45. unzip -j 26104-700.zip
46. unzip -j 26104-700_ANSI_C_source_code.zip
go back to Asterisk folder /usr/src/asterisk-1.8.0-rc2
47. cd ../.. /..
48. wget http://sourceforge.net/projects/asterisk-amr/files/1.8.0-rc2_crypto_offer.diff/download
Apply the patch
49. cd asterisk-1.8.10.1/ && patch -p2 < ../1.8.0-rc2_crypto_offer.diff
Go to asterisk-1.8.0-rc2/ folder
50.
50. cd asterisk-1.8.10.1
Recompile Asterisk ,
51. make ; make install
52. asterisk -rvvvvvvvvvvv

================================
CentOS后记:
设置runlevel 3
编辑/etc/inittab
id:3:initdefault:
安装vncserver
yum install vnc
================================
每小时reboot一次:
cd /etc/cron.hourly/
touch reboot
chmod 777 reboot
#!/bin/sh
/sbin/reboot
================================
# service iptables save
# service iptables stop
# chkconfig iptables off
================================
启用amr codec
vi sip_general_additional.conf
修改
disallow=all
allow=ulaw
allow=alaw
为
allow=all
重新启动Asterisk
