TDM400P PSTN-In and PSTN-out Settings

角色

假如我们有两个FXO ports，分别插入TDM400P的slot-1 and -2。

1）把 /etc/asterisk/dahdi-channels.conf的context=from-pstn更改

在dahdi-channels.conf，为什么有两个context呢？

原来第一context是我们平时用的context，就是有人打电话进来时，去哪里。第二个context，如果在第一个context在extensions.conf找不到的时候，就会找这个default（在extensions.conf 里的default context）。
