Call routing system

I have simple scenario based question.Basically, I would like to establish a system in which when I call my telephone line 1, it should prompt me to dial another number. Once I give it my number, then system should use telephone line 2 to dial the given number and Connect my call.
What kind of devices do I need for a very simple system. Sorry, If it is just too simple question. I googled but I could not get the exact results that I want. One expert advise is better than google results.
