creating ports and initiating communication between client and server

Question

what i need is a server that listens to 5060 port , when the client sends data to that port the server should open up another port ( any port after 1250 i believe ) and forward the clients data to that port keeping 5060 idle so it can perform the same function for the next client

so basically i need the server to a) open up multiple ports one for each client b) get the voice data from the client and be able to send voice data to that client

i m looking into the hardware specs and other such details of the scenario so i dont have time to make such a program myself if theres a code that i can run directly ( both server and client side ) on visual studio .net 2010 that will perform these tasks then that would be extremely helpful

thanks alot in advance

Answer 1

Sounds like a typical TCP socket server implementation. I don't know C# but I'm sure there's a mapping in there of the Berkeley Sockets / Winsock listen() and accept() functions, which do just what you're looking for at the raw sockets API level. I imagine you should be looking for a TCPServer or TCPSocket class (or similar) in the .Net library.
