Asterisk - case study
Hello, dear LQers.
After discovering, that your responses are often very helpful I decided to ask you for a help with a bigger problem.
Recently, I've been playing with Asterisk and VoIP, doing some simple "use of" examples. Now, I came up with an idea, but I don't know how to start implementing it.
Let's imagine a simple authentication system. User gets an incoming call from IVR. All he needs to do is to provide a proper password using a DTMF keyboard. If password is wrong, conversation ends, but in some time interval there is another call, and so on... till proper password is provided.
My question is: could you give me some hints, keywords, places where I can find comprehensive information connected with this particular situation?
