Question

我在Ubuntu 12.04.2 LTS上安装了dahdi 2.7和asterisk 11。我很难配置DAHDI通道。我有一张Digium的AEX 808卡，我的电话线上有8个FXO端口的卡插在卡的端口1上。

我按照http://www.voip-info.org/wiki/view/DAHDI中完全相同的步骤操作在示例安装部分下，除了我编辑dahdi_channels.conf指向与2-8频道的频道号相同的组号，因为我认为星号试图从频道1以外的频道拨打电话，因为它们都是以前在基团= O。

以下是我的配置文件：

chan_dahdi.conf：

[trunkgroups]

; No trunk groups are needed in this configuration.

[channels]
#include /etc/asterisk/dahdi-channels.conf
; The channels context is used when defining channels using the
; older deprecated method.  Don't use this as a section name.

;[phone](!)
;
; A template to hold common options for all phones.
;
usecallerid = yes
hidecallerid = no
callwaiting = no
;threewaycalling = yes
transfer = yes
echocancel = yes
echotraining = yes
immediate = no

使用这些配置文件，当我启动星号时，我收到以下与DAHDI相关的错误：

[Aug  8 15:56:26] WARNING[25198] chan_dahdi.c: Unable to specify channel 1: Device or resource busy
[Aug  8 15:56:26] ERROR[25198] chan_dahdi.c: Unable to open channel 1: Device or resource busy
[Aug  8 15:56:26] ERROR[25198] chan_dahdi.c: Unable to register channel '1'

这是来自unix终端的lsdahdi的结果：

### Span  1: WCTDM/0 "Wildcard AEX800" (MASTER) 
  1 FXO        FXSKS       (In use) (EC: VPMOCT032 - INACTIVE)

  8 FXO        FXSKS       (In use) (EC: VPMOCT032 - INACTIVE)  RED

我不确定为什么会说“正在使用”，因为目前没有正在处理的电话。我不确定这是否是AEX808卡的默认输出。如何让我的DAHDI使用星号？我做错了什么？

dahdi显示状态的结果在星号中：

 astersik*CLI> dahdi show status
 No such command 'dahdi show status' (type 'core show help dahdi show' for other possible commands)

输出dahdi_cfg -vvvv：

Answer 1

检查输出：

dahdi_cfg -vvvvv

Answer 2

经过多次调查，我意识到DAHDI安装不正确。我从系统中删除了DAHDI和星号，然后重新安装了所有内容以使其正常工作。
