How to automate the some dailing sequences when you dial customer care or any other computerized system

Yes , you heard me right you can simply automate most of your operations like talking to a customer care representative.
Lets first analyze what happened when you dial your customer care you want to directly talk to customer care representative and you want to cut out the crap that you have to listen and press the corresponding keys on your phone to go forward.
So when you dial number, +12345678, followed by “p” character, which means pause. The “p character will pause the dial sequence for 1 second“. If you find 1 second is not enough, you can enter more “p” characters
If you want to automate the call and don’t want to press the keys do it this way.
Lets assume that your customer care no is 1234 and the combination of keys you have to press is 1120
So to automate this process type 1234p1p1p2p0 and press the dial button you will be directly routed to the customer care representative ,you can use this procedure to answer any automated system.
