dtmf dial recording for playback to bypass automated dial-in systems I'm looking for an app that would offer the ability to (among other things) record your dtmf key presses into a sort of recording or macro.  The reason behind this would be to go through calling a 1-800 number and pressing various sequences of:

1,3,0,# etc 


till you get a live person.  Obviously the ability to "pause" for a certain amount of time will also needed to be added.

Does something like this exist? If not how hard would it be to make an app that does this function?
The iOS Contacts app allows pauses and waits to be programmed into phone numbers. 

With the number input pad visible, press the special characters key on the lower left.

This will reveal options to input 2 second pauses (you can use multiple pauses to increase the time) or to wait until the dial key is pressed again.
