篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了如何在FreeSWITCH开源软交换安装Sangoma-A400模拟卡相关的知识，希望对你有一定的参考价值。
参考技术A 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

在默认的FreeSWITCH 启动模块中添加添加freetdm 模块
编辑文件 vi /usr/local/freeswitch/conf/autoload_configs/modules.conf.xml 删除注释，确认freetdm 模块已经被添加
<load module="mod_freetdm"/>
检查ftdm 模块加载状态
运行 fs_cli 命令，进入到freeSWITCH CLI
