收听远程计算机发送的来电显示（C＃） [英] Listening to Caller ID sent by remote computer (C#)
问题描述
您好。我有一个VoIP调制解调器，我把它连接到我家的电脑。我用作服务器的程序是 YAC（又一个来电显示）。在我的笔记本电脑中，由于我使用Ethereal来收听来电显示信息，这里有一个示例文字：
Hi. I have a VoIP modem and I connect it to my family's computer. The program that I use which serves as a server is YAC (Yet Another Caller ID). In my laptop, since I used Ethereal to listen to the caller ID info, here's an example text:
.. k..h .....`..E..I9d @ ... .......... |？）。 .... Ey.YP ....... @ CALLYAC 测试电话〜（425）555-1212
..k..h.....`..E..I9d@...?..........|).....Ey.YP.......@CALLYAC Test Call ~(425) 555-1212
正如我所看到的那样在十六进制编辑器和分组信息中，MAC目的地与"... K..h"相关联，源与"....."相关联，类型（IP）与0x0800相关联。使用".."，接下来是Internet协议（E..I9d @ ..？.........），包含源端口，目标端口，seq，ack和len的传输控制协议（不知道seq和ack是什么但我打赌"len"代表"length"并且指的是如果我是正确的字节数），以及TCP Segment Data，它们有类似这样的& "@CALLYAC测试呼叫〜（425）555-1212"。
As I can tell by looking at the hex editor and packet information, the MAC Destination are associated with "..K..h", the source are associated with ".....`", a type (IP) with 0x0800 which is associated with "..", next is Internet Protocol (E..I9d@..?.........), Transmission Control Protocol that contains source port, destination port, seq, ack, and len (don't know what seq and ack is but I bet "len" stands for "length" and refers to number of bytes if I'm correct), and TCP Segment Data, which have something like this "@CALLYAC Test Call ~(425) 555-1212".
我真正感兴趣的一件事是@CALL，但我更倾向于具体，因为有两个端口：一个来源端口和目标端口。当然，它可能总是不是33个字节，因为来电显示中的某些文字可能是错误的。
One thing that really interest me is @CALL, but I'd rather be specific since there's two ports: a source port and destination port. Of course, it may always not be 33 bytes because some text in Caller ID can be wrong.
当我查看代码时：
< font face ="Courier New，Courier，Monospace"> TcpListener server = null ;
尝试
{
//在端口13000上设置TcpListener。
Int32 port = 13000;
IPAddress localAddr = IPAddress.Parse（" 127.0.0.1"）;
// TcpListener server = new TcpListener（port ）;
server = new TcpListener（localAddr，port）;
/ /开始侦听客户端请求。
server.Start（）;
//用于读取数据的缓冲区
字节[] bytes = new 字节[256];
字符串数据= null ;
< br> //输入监听循环。
while （ true ）
{
Console.Write（"Waiting a connection ..."）;
//执行阻止调用接受请求。
//您也可以在这里使用server.AcceptSocket（）。
TcpClient client = server.AcceptTcpClient （）;
Console.WriteLine（" Connected！"）;
data = null ;
//获取用于读写的流对象
NetworkStream stream = client.GetStream（）;
int i;
//循环接收客户端发送的所有数据。
while （（i = stream.Read（bytes，0，bytes.Length））！= 0）
{
//将数据字节转换为a ASCII字符串。
data = System.Text.Encoding.ASCII.GetString（bytes，0，i）;
Console.WriteLine（" Received：{0}"，data）; < br>
//处理客户端发送的数据。
data = data.ToUpper（）;
byte [] msg = System.Text.Encoding.ASCII.GetBytes（data）;
//发送回复。
stream.Write（msg，0，msg.Length）;
Console.WriteLine（" Sent：{0}"，data）;
}
//关闭和结束连接
client.Close（）;
}
catch （SocketException e）
{
Console.WriteLine（" SocketException：{0}"，e）;
}
最后
{
//停止侦听新客户端。
server.Stop （）;
}
Console.WriteLine（" \\\
Hit enter to continue ..."）;
Console.Read（）;
TcpListener server=null;
try
{
// Set the TcpListener on port 13000.
Int32 port = 13000;
IPAddress localAddr = IPAddress.Parse("127.0.0.1");
// TcpListener server = new TcpListener(port);
server = new TcpListener(localAddr, port);
// Start listening for client requests.
server.Start();
// Buffer for reading data
Byte[] bytes = new Byte[256];
String data = null;
// Enter the listening loop.
while(true)
{
Console.Write("Waiting for a connection... ");
// Perform a blocking call to accept requests.
// You could also user server.AcceptSocket() here.
TcpClient client = server.AcceptTcpClient();
Console.WriteLine("Connected!");
data = null;
// Get a stream object for reading and writing
NetworkStream stream = client.GetStream();
int i;
// Loop to receive all the data sent by the client.
while((i = stream.Read(bytes, 0, bytes.Length))!=0)
{
// Translate data bytes to a ASCII string.
data = System.Text.Encoding.ASCII.GetString(bytes, 0, i);
Console.WriteLine("Received: {0}", data);
// Process the data sent by the client.
data = data.ToUpper();
byte[] msg = System.Text.Encoding.ASCII.GetBytes(data);
// Send back a response.
stream.Write(msg, 0, msg.Length);
Console.WriteLine("Sent: {0}", data);
}
// Shutdown and end connection
client.Close();
}
}
catch(SocketException e)
{
Console.WriteLine("SocketException: {0}", e);
}
finally
{
// Stop listening for new clients.
server.Stop();
}
Console.WriteLine("\nHit enter to continue...");
Console.Read();
我注意到它只侦听特定的IP地址，但我想要一个程序来监听任何IP地址（好的，私有IP地址，但它不一定是C类私有IP地址） ，特别是192.168.xx）。因此，当我使用来电显示信息检测到数据包时，我可以提取来电者姓名和来电号码。此外，由于TTY（电传打字机;用于聋/听力诅咒）无法听到（它只闪一盏灯），我可以播放音频文件让我知道我接到了一个电话，没有购买一个在TTY电话响铃时发出声音的电话报警器，我将自己编码。
I noticed that it only listens to specific IP address but I wanted a program to listen to any IP address (well, private IP address but it doeesn't have to be a Class C Private IP Address, notably 192.168.x.x). So when I detect the packet with Caller ID information, I can be able to extract the caller name and caller phone number. Plus, since the TTY (teletypewriter; used for the deaf/hearing imparied) can't be audible (it only flashes a light), I can be able to play an audio file to let me know that I got a phone call, without purchasing a phone alerter that makes sound when TTY phone rings, which I'll do coding by my own.
偏离主题：对于那些想要质疑我使用我的TTY而不是VoIP的人（Vonage，我目前正在与Comcast一起使用），我首先使用有线调制解调器，第二个连接到电缆调制解调器的Motorola VT2142电话适配器，以及连接到我的电话适配器的第三个路由器。我的信号非常清晰，没有任何乱码。 TTY，以及我的电话适配器和路由器在楼下，而我的笔记本电脑位于楼上，所以由于我一直使用笔记本电脑，我无法知道是谁打电话给我，但即使我已经下载了YAC（还记得我提供的链接吗？）并运行YAC Listener，它没有能够播放音频文件让我知道，所以如果我能帮助检测我想要的数据包将会很棒获取来电显示信息，我不必错过任何一个电话。我的路由器是D-Link DI-524。
Off-topic: For those who want to question me about using my TTY over VoIP (Vonage, which I'm currently using with Comcast), I have the cable modem first, Motorola VT2142 phone adapter second that connects to cable modem, and router third which connects to my phone adapter. I get very clear signal without any garbled text. The TTY, along with my phone adapter and router are downstairs, whereas my laptop are located upstairs, so since I use my laptop all the time, I can't be able to know who calls me, but even though I have downloaded YAC (remember the link that I've provided?) and run a YAC Listener, it doesn't have the ability to play audio files to let me know, so it will be great if I could help detect the packet that I wanted to get when getting caller ID information and that I don't have to miss a phone call. The router that I have is D-Link DI-524.
推荐答案
好的。我有一个关于从我的笔记本电脑分配到192.168.0.2的TCP端口的后续问题。
OK. I have a follow-up question about listening to TCP port from 192.168.0.2 that my laptop's assigned to.
IPAddress ip = IPAddress .Parse（ " 192.168.0.2" ）;
IPAddress ip = IPAddress.Parse ( "192.168.0.2" );
TcpListener 服务器;
TcpListener server;
//
TcpClient client;
TcpClient client;
NetworkStream stm;
NetworkStream stm;
public Form1（）
public Form1 ( )
{
InitializeComponent（）;
InitializeComponent ( );
尝试
try
{
server = new TcpListener （ip，10629）;
server = new TcpListener ( ip , 10629 );
server.Start（）;
server.Start ( );
labelListener.Text =
labelListener.Text =
"听取连接..." ;
"Listening for a connection...";
bool pending = server.Pending（）;
bool pending = server.Pending ( );
而 （！server.Pending（））
while ( !server.Pending ( ) )
{
pending = server.Pending（）;
pending = server.Pending ( );
if （server.Pending（））
if(server.Pending())
client = server.AcceptTcpClient（）;
client = server.AcceptTcpClient ( );
}
labelListener.Text = " Connected！\ n" ;
labelListener.Text = "Connected!\n";
}
catch （ SocketException ex）
catch ( SocketException ex )
{
MessageBox .Show（ex.ToString（））;
MessageBox.Show ( ex.ToString ( ) );
}
}
当我调试代码时，" client = server.AcceptTcpClient（）;"因为"服务器"而没有被执行不接受待处理的连接。有办法吗？
As I've debugged the code, "client = server.AcceptTcpClient ( );" doesn't get executed because the "server" doesn't accept pending connections. Is there a way around it?
