dahdi安装笔记

一、使用fxstest

dahdi-linux-complete-2.11.1+2.11.1/tools

使用make && make install 生成的fxstest复制到/usr/sbin 目录下去

二、在astrtisk -r 后的界面module load chan_dahdi.so 错误

[Aug 24 10:47:12] WARNING[11919]: pbx.c:7074 ast_register_application2: Already have an application 'DAHDISendKeypadFacility'

[Aug 24 10:47:12] ERROR[11919]: chan_dahdi.c:12653 mkintf: Signalling requested on channel 1 is FXO Loopstart but line is in FXO Kewlstart signalling
[Aug 24 10:47:12] ERROR[11919]: chan_dahdi.c:17228 build_channels: Unable to register channel '1'

更改vim /etc/dahdi/system.conf的内容

fxsks=1
echocanceller=mg2,1
fxols=2
echocanceller=mg2,2
# channel 3, WCTDM/4/2, no module.
# channel 4, WCTDM/4/3, no module.

# Global data

loadzone        = cn
defaultzone     = cn

----------------
fxsks=1 改为 fxols=1
fxols=2 改为 fxsks=2
可以使用dahdi_cfg -vvv  
root@povodo:/etc/dahdi# dahdi_cfg -vvv
DAHDI Tools Version - 2.11.1


DAHDI Version: 2.11.1
Echo Canceller(s): 
Configuration
======================

Channel map:


Channel 01: FXO Loopstart (Default) (Echo Canceler: mg2) (Slaves: 01)
Channel 02: FXS Kewlstart (Default) (Echo Canceler: mg2) (Slaves: 02)


2 channels to configure.


Changing signalling on channel 1 from FXO Kewlstart to FXO Loopstart
Setting echocan for channel 1 to mg2
Setting echocan for channel 2 to mg2
可以看出来： channel 01是FXO Lookstart
channel 02是FXS Kewlstart
三、reload时出错
Error[4663]: chan_dahdi.c:10946 build_channels: Unable to reconfigure channel '2' 
Error[4663]: chan_dahdi.c:11970 reload: Reload of chan_dahdi.so is unsuccessful!
解决办法：

在chan_dahdi.conf关联dahdi-channels.conf（chan_dahdi.conf的最后一句是#include dahdi-channels.conf） 且这两个文件中有两份关于channel 2的配置（删除chan_dahdi.conf的channels 2的配置）

四、make all 是报错

make -C linux all
make[1]: Entering directory `/usr/local/src/dahdi-linux-complete-2.11.1+2.11.1/linux'

 yum install kernel-devel
