C# Listen TCP Port

Question

I want to listen a TCP port. The scenario: SIP server, and client-program. The SIP server may use port 5010 to listen and establish multiple connections. The client connects from his pc to the server via port 5010. When a packet is received on that port, an event must be triggered on the client PC. Any ideas where to start?

Accepted Answer

Assuming you're working in .NET, look at TcpClient and TcpListener.

Here's the MSDN documentation on TcpListener: https://msdn.microsoft.com/en-us/library/system.net.sockets.tcplistener(v=vs.110).aspx
