验证电话号码 [英] Validating phone numbers

问题描述

我有一个电话号码列表，其中一些是有效的，而有些却不是.我必须编写一个简单的程序，该程序将检查哪个电话号码有效和哪个电话号码无效.
我曾想为此使用SerialPort，但是如何在第一次发出哔声后(有人接听电话之前)或从运营商处收到电话号码无效的消息后直接断开连接?
还是有其他解决方法?

在此先感谢

I have a list of phone numbers, some of them are valid and some of them aren''t. I have to write a simple program, which will check which phone number is valid and which isn''t.
I thought to use SerialPort for this, but how can I disconnect directly after the first beep (before somebody answers the phone) or after I got message from the carrier that the phone number isn''t valid?
Or may be there is some other way to solve it?

Thanks in advance

推荐答案

我不认为此处应使用串行端口.最好使用语音调制解调器并使用电话api为您进行呼叫.这还可以为您提供有关您正在进行的呼叫状态的反馈.

祝你好运！

I don''t think the serial port is what should be used here. It would be better to use a voice modem and use the telephone api to do the calling for you. This can also provide you with feedback about the status of the call you''re making.

Good luck!
