星号TDM410 [英] Asterisk TDM410

问题描述

这本身不是编程问题.我正在尝试构建一个包含以下内容的系统:

This is not a programming question per se. I am trying to build a system which consists of the following:

1. 用户使用常规座机拨打电话系统
2. 某些处理由星号完成
3. 呼叫被转接到一个外部号码(另一个座机/移动电话)

现在，我希望用户可以同时拨打至少2条线路.我想知道以下内容:

Now I would like atleast 2 simultaneous lines on which the user can call. I would like to know the following:

1. TDM410是否可以实现我想要达到的目标?
2. 由于我要进行电话转接，因此是否需要额外的线路?还是可以在同一条线上做?例如对于一个用户，我需要一条传入线路和一条传出线路，还是可以在同一条线路上同时进行接收和转发?

我都有两本星号书籍，但仍不清楚要购买哪张卡.带4 FXO的TDM410是正确的吗?我正在考虑TDM410，因为它有4条线，这样我就可以使用两条输入线路和两条输出线路.我对吗?有人可以指点我到链接/在线商店吗?

I have both asterisk books but am still unclear as to which card to purchase. Is the TDM410 with 4 FXO the right one? I am thinking of TDM410 because it has 4 lines so that I can use two for incoming and two for outgoing. Am I right? Can someone please point me to a link/online store?

非常感谢您的宝贵时间.

Thank you very much for your time.

PS-我不想使用SIP.我想使用POTS拨打所有电话(传入和传出)

PS- I do not wish to use SIP. I want to use POTS for all my calls (incoming and outgoing)

推荐答案

带有4个FXO模块的TDM400将满足您的需求.

The TDM400 with 4 FXO modules will work for what you need.

当您在一条线路上接到呼叫时，该线路正忙，您必须使用另一条线路转接呼叫(星号将桥接呼叫，但为此需要2条线路).您可以直接从Digium购买 .

When you receive a call on one line, then that line is busy and you must use a different line to forward the call (Asterisk will bridge the calls but it needs 2 lines for that). You can buy them directly from Digium.

如果您希望能够接收来自2条线路的呼叫，则至少需要3条固定电话；第三行将是您用来转接呼叫的那一行，但是一次只能转接一个呼叫，而另一个人则必须等待.如果您不希望这样做，则需要4条固定电话.

You need at least 3 landlines if you want to be able to receive calls from 2 lines; the third line will be the one you use to forward the calls, but only one call can be forwarded at at time and the other person will have to wait. If you don't want that then you need 4 landlines.
