无法创建'DAHDI‘类型的通道(原因17 -用户正忙)

Question

我的电脑里有6个带有TDM2400p的红色FXO。我已经安装了asterisk和dahdi驱动。场景是

jitsi-> asterisk服务器->模拟PBX ->座机

我对此场景进行了如下配置

在chan_dahdi.conf文件中

; General options
[channels]
usecallerid=yes
hidecallerid=no
callwaiting=yes
threewaycalling=yes 
transfer=yes
echocancel=yes
echocancelwhenbridged=yes
rxgain=0.0 
txgain=0.0
;FXO Modules
group=2
echocancel=yes
signalling=fxs_ks
context=Incoming
channel=1-20

在astrisk中加载模块后，给出了下面的o/p

module load chan_dahdi.so

在我的extension.conf文件中，我为用户编写了拨号计划，因此sandeep是jitsi用户，81和88是座机号码。

clearglobalvars=no

加载分机和dahdi后，我从jitsi拨打了81，但asterisk给出了o/p，如下所示，jitsi上出现忙音

-- Executing [81@myphones:1] Dial("SIP/sandeep-00000000", "DAHDI/1,20,rt") in new stack
-- Called 1

== Spawn extension (myphones, 81, 2) exited non-zero on 'SIP/sandeep-00000000'

解决这个问题的任何帮助。

谢谢

Answer 1

看起来FXO端口没有插入(或者电池电量不足)。它显示红色警报，在模拟FXO端口上，表示卡无法检测到电话公司提供的电池电压的存在。

此外，通常情况下，当您通过FXO端口拨出时，您需要提供要拨出的数字。如Dial(DAHDI/1/xxxx)。

Answer 2

我的问题解决了。电池电压不正确。非常感谢
