I need to create a voice chat application .
My preference is to use QT to develop client program as well as the server.
The Clients are identified by a particular no.
So when each client try to communicate with other client's , they should first get the connection details for the client to which it needs to be connected from the server.
Server has a database , which stores the client's connection details ..
When i searched in Google i found that SIP Protocol can be used for this purpose.
Can anyone give me some idea , how to use this sip protocol in this scenario , as well as what all tools i can use along with QT to code this easily ..
I don't have much idea about sip..
