如何在FreeSWITCH开源软交换安装Sangoma-A400模拟卡
FreeSWITCH是目前非常流行的开源软交换平台，支持IPPBX，软交换调度，IVR系统，呼叫中心等等解决方案，同时支持PSTN的接入方式。Sangoma模拟语音卡可以通过FreeTDM模块和freeSWITCH实现通信。
准备工作
检测板卡配件，确认板卡的RJ11配线，sangoma附件配置包含了RJ11的窄头线。
如果支持FXS，板卡必须上电。如果A400无FXS也需要上电。并且检测12V电脑电源接口
插入模拟板卡，确认支持PCI-E或者PCI卡
通过系统命令 lspci检查系统是否检测到语音板卡，执行系统命令，lspci-vvv，可以看到如下结果：
05:04.0 Network controller: Sangoma Technologies Corp. A200/Remora FXO/FXS Analog AFT card
Subsystem: NEC Corporation Device 1300
Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx-
Status: Cap- 66MHz- UDF- FastB2B- ParErr- DEVSEL=medium>TAbort-<TAbort-<MAbort->SERR-<PERR- INTx-
Latency: 255(1250ns min, 3750ns max)
Interrupt: pin A routed to IRQ 185
Region 0: Memory at f7200000(32-bit, non-prefetchable) [size=64K]
解压压缩包
tar xfz wanpipe-current.tgz
cd wanpipe-<version>.tgz
编译板卡驱动和freetdm
执行编译安装命令
make freetdm
make install
下载安装配置FreeSWITCH
安装linux Centos支持包
yum install expat-devel openssl-devel libtiff-devel libX11-devel unixODBC-devel libssl-devel python-devel\
zlib-devel libzrtpcpp-devel alsa-lib-devel libogg-devel libvorbis-devel perl-libs gdbm-devel\
libdb-devel uuid-devel@development-tools
安装git以后，使用git安装 freeSWITCH
安装FreeSWITCH
git clone git://git.freeswitch.org/freeswitch.git
cd freeswitch
./bootstrap.sh
编译前，添加freetdm模块，编辑modules.conf文件，注释掉libs/freetdm/mod_freetdm模块，保存文件。执行
./configure
make
make install
make all install cd-sounds-install cd-moh-install//安装语音文件和语音等待文件
配置Sangoma板卡文件
执行/usr/sbin/wancfg_fs命令，启动配置脚本，通过选项来一步步配置板卡
[root@localhost sbin]# wancfg_fs

CentOS63264位安装AdobeFlashPlayer组件的方法
前几天一个网友在Linux CentOS6服务器中的某个需要远程操作的项目需要使用到Adobe Flash Player组件，直接通过YUM方式安装不了，于是通过强大的搜索，还是可以解决到安装方法的，通过重新加载安装Adobe RPM包后再YUM安装组件即可实现，这里就记录下来以便以后有需要。
第一、安装Adobe YUM RPM包
1、64位
复制代码代码如下:
rpm-ivh
rpm--import/etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
2、32位
复制代码代码如下:
rpm-ivh
rpm--import/etc/pki/rpm-gpg/RPM-GPG-KEY-adobe-linux
然后我们选择当前CENTOS6的版本执行。
第二、更新
复制代码代码如下:
yum check-update
第三、安装
复制代码代码如下:
yum install flash-plugin nspluginwrapper alsa-plugins-pulseaudio libcurl
执行命令安装，然后会有两处需要输入y回车。
最后，在安装完毕之后且没有报错基本就安装成功，然后登入我们的项目，比如浏览器可以看到Adobe Flash Player组件安装完毕。
CentOS使用MPlayer有图像无声音的解决方法
CentOS在安装完MPlayer后，有些人出现了有图像无声音的情况，而网上大部分都是Linux系统的解决方法，那么CentOS系统要如何解决呢？下面小编就给大家介绍下Linux使用MPlayer播放器无声音的解决方法。
步骤：
1.安装alsa相关的包，因为rhel6和centos6以上的版本使用声卡配置都是alsa了，所以声音可能与缺这个相关的包有关。
yum install-y*alsa*
2.下在解码包 all-xxxxx.tar.bz2
3.解压all-xxxxx.tar.bz2
tar-xf all-xxxxx.tar.bz2
4.创建一个文件夹
mkdir/usr/local/lib/codecs
5.进入all-xxxx
cd all-xxxxxx
6.将里面的所有文件移到第4部创建出来的文件夹中
mv-f/all-xxx/*/usr/local/lib/codecs
7.重新。/configure.这次加上参数--codecsdir=/usr/local/lib/codecs
。/configure--codecsdir=/usr/local/lib/codecs
8.make
9.make install
上面就是CentOS使用MPlayer无声音的解决方法的介绍了，MPlayer无声音很可能是缺少alsa包所导致，下载解码包解压，按照本文介绍的方法进行相关处理。
