星号如何在拨号前检查一个号码是否占线 [英] Asterisk how check if a number is busy before dialing it

问题描述

作为刚刚安装了他的第一台 asterix 服务器的初学者，我遇到了一个小问题.我想在实际拨打之前检查我拨打的号码是否占线.

As a beginner that just installed his first asterix server I came across a small issue. i want to check if a number that i dial is busy or not before actually dialing it.

例如我会拨打 0904 => 号码忙 => 重定向到 0905

So for example I would call 0904 => number busy => redirect to 0905

但是，我不希望它在忙时先拨 0904，而是立即将其重定向到 0905.

However I don't want it to dial 0904 first if its busy but just instantly redirect it to 0905 instead.

我有一个非常基本的设置，只有 3 个用户.其中 2 个在支持"队列中，其中一个在管理员"队列中

I have a very basic setup with just 3 users. 2 of them are in a queue "support" one of them is in the queue "admin"

我已经看到并阅读了一些关于检查频道是否可用的内容，但我并不完全理解这一点，我不确定是否可以更轻松地完成.

I have seen and read a little about checking if a channel is available but i didn't fully understand that and I'm not sure if it could be done easier.

这是我的简单拨号计划，如果我调用 *12，我的简单 python 脚本将只对 0904 执行拨号命令.

Here is my simple dialplan, if i call *12 my simple python script will just execute the Dial command to the 0904.

exten => *12,1,Answer()
same => n,set(PHONE_EXTEN=0904)
same => n,AGI(test-agi.py,${PHONE_EXTEN})
same => n,Hangup()

推荐答案

没有办法知道外部号码是否忙.

There is no way know if external number is busy.

如果 number 是您的分机，您可以使用 GROUP/GROUP_COUNT 计算呼叫次数，或者您可以检查分机状态和提示，如文档中所述

If number is your extension, you can count calls using GROUP/GROUP_COUNT or you can check extensions states and hints, like described in docs
