;定义两个电话客户端PHONE00和PHONE01
PHONE00=SIP/8000
PHONE01=SIP/8001


;下面定义了内线电话的拨号规则，当电话拨打80开头的4为号码（_80XX)就转接到PHONE（前面有定义)开头的电话上去，至于是PHONE00还是PHONE01则是将80XX的前两位去掉( EXTEN:2)

[internal] 
exten => _80XX,1,Dial(${PHONE${EXTEN:2}},${gtimeout},tr)
exten => _80XX,n,Hangup()


;下面这一段则是定义当公司或者朋友拨打联通wo-call号码时，转接到哪个内线上
;更高阶的做法是做一个轮循弄成call center

;下面定义拨打啥号码时才使用外线联通号码拨出
;这里我是定义了当拨打任意7位以上(注意XX后面有个小数点. 它代表无限长度)
