使用.net的未接来电警报系统 [英] missed call alert system using .net

问题描述

我想开发一个未接来电警报系统。



系统应该拨打专用号码并在一响后拒绝接听电话，

将服务提供商的号码及其位置保存到数据库中，并回复谢谢你的短信。



i不希望有人为我这样做，我只是想知道如何开始这个。





谢谢

save the no and its location with service provider into database, and reply with the thank you sms.

i don't want someone do this for me, i just want to know the way how i can start this.


thank you

推荐答案

系统应该在专用号码上接听电话

the system should receive a call on dedicated no

所以你需要在电话线和PC之间使用调制解调器

So you need a modem between your phone line and PC

并在一次响铃后拒绝该呼叫

and reject the call after one ring

程序向调制解调器发送一个挂机消息

The program sends a hangup message to the modem

保存否

如果数字通过电话系统发送

If the number is sent via the phone system

及其与服务提供商在数据库中的位置

and its location with service provider into database

我不认为任何提供商提供此级别的详情

I do not think any providers offer this level of detail

并回复谢谢短信

创建短信并通过短信服务提供商发送

Create the SMS message and send it via your SMS service provider
