asterisk+Libss7的配置

转自：http://wanchengbuyi.blog.163.com/blog/static/16646183120106217357502/

Libss7的安装过程很简单，一般的步骤如下：

1. dahdi kernel install
2. dahdi tool install
3. libss7
4. asterisk

libss7安装后再编译asterisk。

这里就不再详述安装过程了。只说一下配置。

最开始dialplan是这样写的

exten => 1,1,Dial(dahdi/g1/10086)

结果一直打不通电话

控制台显示如下信息
===============================================
-- Executing [1@from-in:1] Dial("SIP/100-00000001", "dahdi/g1/10086") in new stack
-- Called g1/10086

== Spawn extension (from-in, 1, 2) exited non-zero on 'SIP/100-00000001'

===============================================

因为此线路打不通10086，最后把dialplan改为：

exten => 1,1,Dial(dahdi/g1/97xxxxxx)

问题解决了。
