i need an automated system

Okay, I will do my best to explain. We want you to build a system where you call the phone number from a lead sheet we give you, the call should be done at night so you have the most chance of getting an automated system. When this automated system starts playing it's recorded message we press (star)7 and by hearing a particular response we know what type of brand is the phone. We have the key sheet with the 10 recorded messages that you should hear after pressing (star)7 and what phone brand they represent.
