Create a phone simulation- dial a number

Hi,

Had a look and dont think this question has been asked before.

I am creating some learning on what staff should do if the encounter a fire. Rather than just telling them to dial '3333' I want this to be simulated using a phone key image that they can dial numbers on.

I have added several 'states' to the keypad to give the illusion of it being pressed, but am not sure how I can get the functionality that allows a learner to press the 3 button four times to then generate a message such as 'hello swtichboard'. I would if possible like the other buttons to work, so that if any other key is pressed an incorrect message would be generated.

Thanks in advance for any suggestions, solutions or ideas.
