You'll need a recent modem that supports Caller ID and is supported by Windows. 您需要一个支持来电显示的最新调制解调器，并且受Windows支持。 Windows provides an API for talking to the modem called Telephony Application Programming Interface, aka TAPI. Windows提供了一个用于与调制解调器通信的API，称为电话应用程序编程接口，即TAPI。 Unfortunately, this API cannot easily be accessed from managed code . 遗憾的是，无法从托管代码轻松访问此API。

Your best bet for getting access to Caller ID in managed code would be to use one of the free or shareware TAPI OCX controls that sit on top of the TAPI API, most of them should have a simple API that would give you the incoming number. 在托管代码中访问来电显示的最佳选择是使用位于TAPI API之上的免费或共享软件TAPI OCX控件之一，其中大多数应该有一个简单的API，可以为您提供传入的号码。 Google for something like 'TAPI OCX' or 'TAPI Caller ID' to see what's available. Google可以使用“TAPI OCX”或“TAPI来电显示”来查看可用的内容。

If it's a landline you're talking about, all you would need would be a standard analog modem and a serial port to connect it to. 如果它是你正在谈论的固定电话，你所需要的只是一个标准的模拟调制解调器和一个连接它的串口。 You'd use standard AT-style commands to control the modem and monitor incoming data. 您将使用标准AT样式命令来控制调制解调器并监视传入数据。

If you have a VOIP system, your system provider may have an API available to do this. 如果您有VOIP系统，您的系统提供商可能有一个API可用于执行此操作。 Based on my experience, it will cost extra and be buggy. 根据我的经验，这将花费额外的成本和错误。
